In our modern world, there is one thing that we certainly do not lack. Asphalt, everywhere we look. Roads, highways, parking lots - it is everywhere. ‘Asphalt’ has become the synonymous term for everything grey, mass-built, enormous, and ominous at the same time. Now, there is one company looking to repair this somewhat damaged image of asphalt - by recycling old tar Asphalt and turning it into useful building materials, heat, and electricity. Unique In The World:  100% Recycling A 100% recycling process is unique in and of itself. Pretty much all recycling processes do leave some kind of waste behind. Not this one, as designed by the Dutch company Recycling Kombinatie REKO BV. Back in 2018, construction began on its second thermal cleaning installation (REKO II-plant) in the Rotterdam port area. This cleaning installation is slated to convert up to 1.2 million tonnes of residual materials, which is a mix of tar-bearing asphalt, and roofing felt. Instead, will be turned into primary resources, including sand, gravel, electricity, and heat. 'The REKO crew'. To build a 'machine' this big you need courage, imagination, and the right decision taking! REKO is a producer of sand, gravel, and fillers for mineral-based residuals (urban mining). Asphalt is its main resource and therefore invaluable in its value chain. This asphalt is largely sourced from road construction projects and can no longer be used due to its tar-holding contents, something that is forbidden in construction. It can, however, still be used for its mineral residuals. At the start of the 21st century, REKO BV worked hard on a brand new, highly innovative process, meant as a thermal cleaning of these mineral residuals. Eventually, this research project paid off and led to the very first thermal cleaning installation for Tar Asphalt, built back in 2006 (REKO I-plant). Ever since this installation has had no problems converting up to 600,000 tonnes of mineral residuals per year. This means that over its lifetime, the installation has produced nearly 7,5 million tonnes of sand and gravel for the Dutch building industry. Recommended:  Waste: The Netherlands Creates New Material From Sewage Burning Up Damaging Components The process is fascinating. The asphalt is thermally cleaned in a rotating kiln, at temperatures of 1000 degrees Celsius. This means that all the damaging organic components in the asphalt - including tar - fully burn up. Eventually, this thermal cleaning process leads to clean sand, gravel, and filler, ready for its second life in the construction industry. The other product of this process is the extremely hot waste gas, that allows for a re-capture of energy in the form of steam with the use of a steam boiler, that is subsequently converted to electricity in a steam turbine. Inside the 'tube' - the rotating kiln - where the asphalt is thermally cleaned Each year, the existing installation (REKO I) produces some 30,000 megawatts of electricity - the rough equivalent of the amount of power used by 7,500 households on an annual basis. A significant amount, but it could be even more efficient. This is what the new installation (REKO II) in the Port of Rotterdam is cut out to do. It uses more modern techniques, while also benefiting from the 12+ years of experience that REKO now gained in the field of thermal cleaning. Not only does it use less energy, but it also generates more: it can generate sufficient electricity to power at least 50,000 households for a year. A significant improvement over the previous version that is. Recommended:  Circular-Economy Gets Game-Changer Ioniqua: PET Poster Child Of The Circular Economy This processing technique is the poster child of the circular economy, where residual materials are fully converted, and the chain is genuinely closed. No waste of any kind, only clean sand and gravel and energy and heat. It merely takes the polluting tar-bearing asphalt and processes it in a way that all the polluting and dangerous components are destroyed. That is what REKO does and hopes to do for a much larger market. In the past, only the Netherlands explicitly ruled that tar-bearing asphalt could no longer be used in construction. By now, Belgium has followed, and the rest of Europe is not far behind. This development in the international market makes the new installation even more attractive. Because of the size of the installation, combined with the large-scale reclaiming of the released energy, REKO can decrease the costs to it's customers   According to David Heijkoop, director at REKO: “ Because of the size of our installation, combined with the large-scale reclaiming of the released energy, we can decrease the costs to our customers. Combined with the very favorable location of REKO in the Port of Rotterdam, in a region where is a great lack of sand and gravel which is normally imported from Belgium and Germany – and the possibility that we can transport tar-bearing asphalt over water -, gives us an excellent starting point for the rest of Europe ." World’s Largest Recycling Factory The new installation is set to become the world’s largest recycling factory for polluted building materials. And while you might correctly assume that the burning of the asphalt requires quite a bit of energy, the materials that burn - including the forbidden tar - release up to four or five times more power than that goes in. Plus, the new installation has the added feature of providing heat as well as electricity. This heat can be transported as hot water to the district heating in the surrounding area. A nice extra is that there is a choice between the amount of electricity and heat generated: meaning, if the city of Rotterdam requires more heat, REKO can deliver this. If it is not needed, for instance, during hot summer months, then it can all be converted into electricity. Once again, a genius move that many will benefit from. To check the whole process of the world’s largest recycling factory you need a state to the art control room! The installation does, therefore, not only serve the company by producing the sand, gravel, and filler that it sells but also the environment and the surrounding area—triple win. “ REKO can produce about one and a half million tonnes of clean sand and gravel. This also means that a lot less sand and gravel has to be dug up, which means that the landscape will be impacted much less—finally, nothing of what REKO processes have to be disposed of. None of the harmful elements will end up in the environment—another good thing for the landscape and nature. Ships will no longer be transporting imported sand and gravel that has been dug up in other countries. Instead, they will bring tar-bearing asphalt that we will convert into clean sand and gravel, which can be put to good use in the Dutch construction industry. It is the circular economy. ” If everything goes according to plan, the installation is set to become operational in a few months, by September 2020. Then it will start to turn old tar containing roads into new building materials, electricity, and heat - without any harmful emissions or residuals. Now that’s the kind of thinking that we need to save the world. Before you go!

Dumpster diving. The term alone is guaranteed to put a smile on your face - whether it is one of actual enjoyment or disbelief, I am not sure.  Dumpster Diving: Food Perfectly Good Thrown Away Yet this phenomenon, where people sometimes quite literally ‘dive’ in the dumpsters in their neighborhood to hunt for thrown-away treasures, is seeing an uptake after some of its most famous proponents recently made headlines again. When was the dumpster invented? The word "dumpster", first used commercially in 1936, came from the Dempster-Dumpster system of mechanically loading the contents of standardized containers onto garbage trucks, which was patented by Dempster Brothers in 1935. Recommended:  Vegan Food You Need To Develop Your Muscles: Protein Power With the loot varying from hundreds of left-over desserts to household equipment and sometimes even cash, it is not hard to see why some have turned this somewhat peculiar hobby into a way of life. A fact is that we, as the collective world population, are throwing away too many perfectly good things. From food to clothes and from electronics to toys: consumerism has taken a turn for the worse, now that we discard items once we are ‘done’ with them, rather than after they have been used thoroughly. {youtube}                                                    Dumpster diving: free food, free flowers, free fun  Take the issue of food waste. Every year, an average of one-third of the food that is produced in the world for human consumption is wasted. Simply thrown away. I don’t want to risk sounding too condescending, but the old mom-trick is painfully relevant here: "You should eat your dinner, poor children in Africa would kill for it."   And while it is a cliche of the worst kind, it, unfortunately, rings true. While some of us are having the luxury of discarding perfectly good food items, others are starving. The world’s wealth has always been distributed unequally - but so has the food supply. The billions and billions worth of food thrown out in the western world, simply because it is a day past the expiration date, is inexcusable.   Recommended:  Super Food Designed To Match Your Genome: Star Trek Reality Dumpsters? Can you take stuff from it? Is Dumpster Diving Illegal? It is generally considered legal for people to rummage through trash that has been left in a public area such as a curb for pickup. Once the garbage is placed in such a place, the person has basically forfeited their ownership rights to the items, as the property is now in the public domain Dumpster Diving: 'So Many People Are Struggling To Get By' Coming back to dumpster diving. A lot of people are claiming that they are doing it as a way of showing their outrage with consumerism and waste. Others just say that it is fun and addictive. There’s this Dutch guy, Theo Vreugdenhill, who claims that he merely tries to ' save perfectly good food from the trash.'  As he says, “I simply cannot stand by idly if good food is thrown away, only because there is a tiny dent in it, happens to be slightly damaged, or is nearing its expiration date. Especially when I look around and see how many people are struggling to get by. ” He is not doing it for himself, quite the contrary. He is a preacher in a local church and takes two full crates with him to service on Sunday, for those who are unable to provide in their own needs. The products that he finds? Quite diverse, actually: from cheese to beer, butter, yogurt, fruit drinks, feta cheese, salads, and fruit. Although he has also come across perfectly good vacuum cleaners and laptops in the past, which just goes to show how careless we are in what we throw away. Not everything can be found in the dumpster: most divers will agree that it is mostly perishable items, such as vegetables, fruit, and bread. So you probably should not entirely be ready to give up the day job and spent your days as a full-time dumpster diver: products like rice, peanut butter, soda, dish soap, and detergent are pretty hard to come by.   Would you still want to try and find your inner dumpster diver and fill your fridge with leftovers? Then you can quite literally take the dive and plunge in the bins headfirst, although you could also try to talk to some shop owners yourself. Especially if your good cause stretches beyond feeding your immediate family, they might be very willing to hold on to that day’s excess for you and hand it to you in a bag instead of making you scour for it. What is a freegan lifestyle? Freeganism is a practice and ideology of limited participation in the conventional economy and minimal consumption of resources, particularly through recovering wasted goods like food through dumpster diving. The word 'freegan' is a portmanteau of 'free' and 'vegan'. Dumpster Diving. Hints, Shared By Experienced Dumpster Divers: Do not wear your Sunday’s best for the dumpster diving part - while it is not nearly as gross as many people suspect, it is not something that you want to do in your favorite shirt and jeans either. Only go dumpster diving at night, preferably after the shops are closed. This way, you avoid awkward situations with shoppers walking out of the store while you are digging around in the trash. Do not climb any fences or force open gates when dumpster diving. Trespassing is not appreciated nor legal, so stay off private property. Stick to the curb-side. Always clean up after yourself. Leaving behind a mess of torn apart bags and scattered trash is bad taste and will most likely set some bad blood. Be a good neighbor and make sure that the people whose trash you are raiding do not mind. Be open about what it is that you are doing: you might get some funny looks from passerby's, who might even think of you as some homeless person. Talk to people who spotted you and explain what you are doing and what you have found.   Very practical: use a headlight when dumpster diving, so that you can freely use your hands while digging; and make sure to bring plenty of bags and boxes and, preferably, a way of transporting your newfound treasures. Recommended:  Superfood! Murnong Gets Back To Our Plates: Australia Not quite ready to go out and dig in your community’s trash bins yet? Then you can do other things to cut back on your food waste. To actively encourage you to do so, you will be happy to find that there are quite a few apps that remind you to do so and give helpful hints. One of those apps is Too Good To Go , designed explicitly for bargain hunters: businesses can post their leftovers in the app at steep discounts (adding up to at least 50-75%), after which shoppers can come in to collect the relatively fresh food at a great price.   Recommended:  Helpful tools and supplies for Dumpster Divers Combat Food Waste: Apps Another popular app is Olio , which allows you to share food with your local community. Handy if you are going on holiday, for instance. Your leftover food can be listed, along with a preferred pick-up point and pick-up time, and people in your community will be able to take it off your hands.   Unsung kind of does the same as Olio, except that it works with volunteers, in a charitable set-up. After posting your ‘offer,’ one of the Unsung volunteers will come to pick it up and deliver it to a local food bank or homeless shelter. The volunteers are the delivery guys who pick up your food and drop it off with people who need it the most. Finally, Eat Me prevents your food from going bad: it creates a timer for all the food that you have in your fridge. Scan the food as you put it in the refrigerator, after which it will alert you if it is about to go bad. A fun fact: this app was the idea of two teenage girls, who are still involved in the company. Look, I don’t care if you are digging through trashcans or donating your leftovers through one of the apps listed above. The essence remains the same: avoiding a situation where you have to throw away food while someone else in your community might be going hungry.

The Fourth of July—also known as Independence Day or July 4th—has been a federal holiday in the United States since 1941. Festivities ranging from fireworks, parades and concerts to more casual family gatherings and barbecues. The Fourth Of July. History The tradition of Independence Day celebrations goes back to the 18th century and the American Revolution. On July 2nd, 1776, the Continental Congress voted in favor of independence, and two days later delegates from the 13 colonies adopted the Declaration of Independence, a historic document drafted by Thomas Jefferson. From 1776 to the present day, July 4th has been celebrated as the birth of American independence. Fireworks: Is It Still Ok? Fireworks are mesmerizing, dreamy, and very romantic. But at the same time, they are not exactly great for the environment. Whether you opt for looking out from behind the relative safety of your window, gawking at the professional show amidst thousands of others in a crowded square.  Recommended:  India’s CO2, Pollution, Artificial Rain: How To Survive?

Where did fireworks originally come from? Some think that fireworks first originated in China around 2,000 years ago. The most popular legend has it that fireworks were discovered by accident when a Chinese cook working in a field kitchen happened to mix charcoal, sulphur and saltpeter (which were all common kitchen items at the time). The fireworks colorful, artistic lights flickering in the sky, accompanied by rhythmic booms reverberating in our hearts, will fill us with joy. With happy and perhaps not so happy memories. It will fill us with love and with good intentions.  And with harmful particulates and elements. {youtube}                                                       Fourth of July Fireworks NYC 2019 from Brooklyn Bridge Park                                                            U nfortunately, all the things that make fireworks so pretty and attractive are exactly those things that make them so bad for us.

All of these elements are made up of carcinogenic and hormone-disrupting substances, that can make its way into our soil, air, and water. Recommended:  Climate Change Efforts On Reducing CO2 Why Not Recycle It? Fireworks and it's 'dirty' chemistry How are fireworks produced? When a firework explodes mid-air thanks to the bursting charge and the black powder, the gas and the heat that are produced ignite the stars. The atoms of the metal powders in the stars absorb that heat energy and their electrons rearrange from their lower-energy ground state to a higher-energy 'excited' state Some of those really bad guys that are present in commonly used fireworks include perchlorates. These are responsible for the explosion, as they feed oxygen in the charcoal-sulfur fuel that powers up the explosive, serving as the so-called oxidizers. The pyrotechnics industry is particularly looking at two types of perchlorates for this: potassium perchlorate and ammonium perchlorate.   Fancy names for something so inherently bad, as they can cause all kind of health problems, most significantly hypothyroidism: an illness that limits the thyroid’s ability to ingest iodine, which will lead to a lack of hormones in the human body - hindering all kind of bodily functions and potentially giving rise to all kind of disorders, especially in children.   Recommended:  Fossil Fuel Will Dominate Energy Use Through 2050: Globally Fireworks have bad effects on children's health Then there are particulates in fireworks. These can be found in the smoke resulting from the burned charcoal and sulfur and will make their way to our lungs. This could pose an instant danger for those suffering from asthma-related diseases. Merely looking at an air-quality monitor spiking out in the hours after a fireworks show should get you concerned about the air that you are breathing.   Do fireworks make it rain? Nonetheless, fireworks are not found to be an actual cause for rain. The concentration of chemicals during even the busiest of firework nights alone are not enough to open the floodgates of the sky. The problem with the argument is that fireworks won't go high enough to introduce the particles into the clouds Fireworks which have been exploded There are even more rather ominous-sounding elements that can be found in your firecrackers, flares, and Roman candles. Strontium, aluminum, copper, barium, rubidium, cadmium: terms that you might remember from your chem class as being rather delicate and dangerous substances, yet that are freely used to color our fireworks. All of them carry nasty side-effects when ingested in high doses, including impairment of bone growth, mental disorders, Alzheimer’s, cancer, skin diseases, paralysis, heart problems, and - in the worst case - death.   Is the smoke from fireworks toxic? Depending on the effect sought, fireworks produce smoke and dust that contain various heavy metals, sulfur-coal compounds, and other noxious chemicals. Barium, for instance, is used to produce brilliant green colors in fireworks displays, despite Fireworks: You Will Be Breathing Highly Toxic Particles Some will object at this point, claiming that it cannot be that bad. Fireworks are, after all, not an everyday event (that is unless you work in Disney World). And are those one or two days per year that we shoot all kinds of garbage up in the atmosphere really something worth worrying over? Especially as the industrial sector keeps on regurgitating substances that are seemingly identical on a daily basis?   Admittedly, the chances of attracting any of the diseases given above for the volumes going up in the air on the fourth of July are so small that they could be considered insignificant. Yet we should not just think about ourselves but consider the impact on our environment as well. Some cities will experience more smog and air pollution on the fourth of July alone than in the previous year as a whole. That is a fact.   Recommended:  Sustainable Polluting Eating Tree Is Cleaning Cities Air Fireworks, distribution case These toxins will get in the atmosphere, in the soil, in the water.

The majority of these chemicals are persistent, which means that they will not break down in nature, but stay in our ecosystems indefinitely.   Are fireworks bad for animals? Research studies show that the loud sounds of fireworks do have an adverse effect on wild animals as well as domestic animals. ... This fear often causes them to flee into roadways which results in more vehicle damage (from large animals such as deer) and an increase in dead animals.

People are trying to live a more durable life, so it is not a surprise that green death is a more discussed topic. More than 80 percent of the British choose cremation over funerals, due to the premiums of space. But they have to know that with each cremation, about 250 kg of carbon dioxide emits into the atmosphere. Become Plant Food We all work towards a greener life. People have been searching online for green burials or natural funerals. New innovators and companies rise to meet this demand. Take an example from Beverly Hills star Luke Perry. He died in 2019 and got buried in a so-called mushroom suit. A mushroom suit burial is a remarkable eco-friendly gift to nature. The suit is made of organic cotton and lined with specialist mushroom spores. The person wearing it will soon be covered with growing mushrooms. Their remains will feed the fungi which rapidly decompose organic matter and remove toxic substances from the environment, in turn providing nutrients to the soil and surrounding plants. Become A Coral Reef In the late 1980s, artificial reefs, made of natural concrete, became an option for cremation. In the United States of America, you have Eternal Reefs, living legacies that memorialize our loved ones. Cremated remains of our loved ones are mixed with concrete to create a so-called 'pearl.' Loved ones can engrave the pearl with plaquettes and inscriptions, while the concrete is still wet. Then, the pearl is left at the bottom of the ocean, to be a new habit for fish and other sea life.

The energy sector has gone through a drastic change, and the gradual transition to renewable energy sources is more than visible. But what may look durable, does not stay that way. This is at least the most occurring concern concerning photovoltaic (PV) solar panels. The Lifetime of Solar Panels Solar panels glimmering in the sun are an icon of all that is green. But while generating electricity through photovoltaics is indeed better for the environment than burning fossil fuels, several incidents have linked the manufacture of these shining symbols of environmental virtue to a trail of chemical pollution. And it turns out that the time it takes to compensate for the energy used and the greenhouse gases emitted in photovoltaic panel production varies substantially by technology and geography. Recommended:  Tiny House WikiHouse With Solar Panels On Roof And Walls They are a long-lasting source of energy, only dependent on solar radiation, and able to supply electricity to our homes. But what happens to solar panels if they don't work efficiently? Discover their journey through the process of recycling in the infographic below: What is the lifespan of solar panels? A lot of people ask this question when they consider solar panels. Research has shown that the lifespan of solar panels is about 30 years before they are dismantled. A 20 percent reduction in power can occur during the lifespan of photovoltaic panels. The maximum reduction is 10 percent between the first 10 and 12 years. This would be 20 percent when the PV panels reach 25 years. In reality, the efficiency of solar panels will decrease by only 6 to 8 percent. So, the lifespan of solar panels could be longer than officially stated. Disposal of Solar Panels From a regulatory point of view, PV panel waste still falls under the general waste classification. At the EU level, there is a single exception, where PV panels are defined as e-waste in the Directive on Waste Electrical and Electronic Equipment (WEEE). The management of waste from photovoltaic panels is regulated by this Directive, as a complement to other regulatory frameworks. Photo by: Ricardo Arduengo. Solar panel debris lies scattered in the aftermath of Hurricane Maria in Humacao, Puerto Rico Manufacturers of solar cells are legally obliged to fulfill specific legal requirements and recycling standards to ensure that solar panels are not becoming a burden to the environment. Photovoltaic manufacturers have been working with government agencies and have thought of several ways to deal with the waste from solar energy. Solar Panel Waste We need to recycle because otherwise, there would be 60 million tons of Photovoltaic panels waste lying in landfills by 2050. The solar cells contain a specific amount of toxic substances, and that would not be a sustainable way to generate energy. {youtube}                                                                Will renewables end up as more landfills? It is a myth that solar panels are not recyclable. It needs time and research to see the full potential of adequate recycling of all solar panel parts. This is why it is necessary for recycling and designing work closely together so that the ability to recycle is guaranteed by using mindful eco-designs. Recommended:  Waste: The Netherlands Creates New Material From Sewage Solar Panel Recycling Processes There are two different main types of solar panels. They both need a different recycling approach. You have solar panels bases on silicon and based on thin-film. At this moment, solar panels based on silicon occurs more often, but that would not imply that the materials of thin-film cells would not be of significant value Research has shown that there are a lot of technologies in recycling solar panels. Some of them show a result of 96% recycling efficiency. They strive to do better in the future. Recommended:  Wind Turbines: Waste From These Blade Runners? Silicon-Based Solar Panel Recycling The process of recycling silicon-based PV panels starts with the disassembly of the actual product to split the aluminum and glass parts. You can reuse almost every piece (95%) of the glass, while all the exterior metal parts are used for the repainting of cell frames. The other materials are heated at 500°C in a thermal processing unit to facilitate bonding between the cell elements. Due to the extreme heat, the embedded plastic evaporates, making the silicon cells ready for further processing. The supported technology makes sure that even plastic is not wasted and is therefore reused as a heat source for further thermal processing. Thin-Film Based Solar Panel Recycling Thin-film based panels are processed more drastically in comparison to silicon panels. First, you need to place them in a shredder. That ensures that the particles are no bigger than 4-5mm. At this size, the lamination holds the inner materials together, breaks, and can, therefore, be removed. The remaining material exists of both liquid and solid substances. A rotating screw is used to separate these remaining materials. Recommended:  Designing Business Models: Reciprocity And Circularity Liquids undergo a dewatering and precipitation process to guarantee their purity. The resulting material goes through metal processing to completely separate the different semiconductor components. However, on average, 95% of the semiconductor material is reused. Solids are polluted with so-called interlayers, which are lighter in weight and can be eliminated by a vibrating surface. The Future Benefits of Solar Waste Management We know now solar panels are recyclable. But are there any other benefits for the economy? Recycling Photovoltaic panels will create more green jobs. PV recycling will recover around £11 billion in recoverable value by 2050. This makes it possible to produce 2 billion new panels, without investing in raw materials. As a result of the ongoing price reductions of solar energy, more households and companies are choosing to invest in solar energy systems. This will create even more economic opportunities in the solar cell recycling sector. Before you go!
