Now techknow investigates the problem with plastic. They throw in the street or throw it in the ocean. We have the technology. I cant touch it . No you cant. So why dont we use it . So you dont know what happens to the plastics you recover . Dr shini somara is a mechanical engineer. Dr. Crystal dilworth is a neuroscientist. Were standing by a pipe marked heated sludge. And im phil torres, im an entomologist. Thats our team. It smells very organic. Now lets do some science. Hey guys, welcome to techknow. Im phil torres and today we are going to be talking trash and a ton of it. Joining me with this trash talk dr. Crystal dilworth, dr. Shini somara. Now first up the water bottle, by some estimates here in the u. S. We use 50 billion of these every year and myth number one is that this is going to be recycled. Correct, actually its probably not going to be recycled. A lot of Water Bottles that we think are headed for recycling facilities end up in landfills and those landfills can have some really negative impacts on the surrounding communities. Its actually quite shocking that a material that is designed to be used over and over again actually only gets used once and what weve done is take a water bottle just like this and follow its journey after its been blue binned to see exactly what happens. The world is addicted to plastic. It was sold to us as the product of the future. Plastic. Plastic. Plastic. This educational video from the 1940s celebrates the convenience of plastic. Here they are in our homes, augmenting our comforts. Back then it was a symbol of the modern times to come. 6decades later, the reality is, the earth is choking on it. According to the United StatesEnvironmental Protection agency, only 9 percent of plastic is making its way into the recycling stream. Thats a people problem, they throw on the street, or throw it in the ocean, unfortunately thats a habit that has to be stopped. Its our addiction to single use plastic for fast food, storage and packaging convenience thats at the root of the problem. Were guilty ah, and we should just admit it. Dr. Steven nutt is a professor of Materials Science at usc. He studies the physics and chemistry of materials like plastic. It seems to have been a material that was developed for convenience but were now, you know, almost a hundred years later paying the price. If you look at the population as a whole, probably the majority have not yet realized the magnitude of the problem. And nothing symbolizes the problem like the omnipresent plastic water bottle. Americans consume water from about 50billion bottles a year. Made from whats called pet, or polyethylene terephthalate. Two monomers. Ethylene glycol and purified terephthalic acid. Are combined to create a polymer. Resulting in a lightweight but strong material. Why then does it last almost to infinity in a landfill . These essentially are the same type of bonds that hold together a diamond. If youre conscientious enough to throw a water bottle into a blue recycle bin, like we do here at techknow, then you probably think that water bottle is gonna be turned into another water bottle. But that may not necessarily be the case. Techknow wanted to find out what happens next. So we followed the water bottle. This is the massive puente facility near los angeles california. Located near a large metropolis, it can take a lot of trash. If you take a football field from post to post 10 feet high uh, fill it up with trash about a third of that or a quarter of that comes over here every day. Three thousand tons a day. This facility offers a glimpse into the world of single stream recycling, because all the recycled material it receives comes from a Single Source bin like this. Convenient, because all recyclables end up in one basket but theres a price. You cant unscramble an egg. Susan collins is a manufacturing engineer who heads up a non profit recycling institute. Once materials get mixed together too much, like glass shards ending up in paper, or plastic bottles ending up in the paper stream or aluminum cans ending up in the plastic stream, all of that is detrimental to recycling. Sorting seems to be a massive component. There are multiple compositions of plastic. When these different plastics are blended together then the recycling becomes difficult to impossible. That is exactly whats happening at the puente plant. That means a bottle wont be turned back into another bottle. But instead it will go on another journey, into the secondary plastic market. One of the myths is that once you place a water bottle in a blue recycle bin it can actually be made back into a water bottle again the technology is there, why isnt it being done more . I cant really speak to the industry of what happens after, you know, the water bottle leaves our facility we just make sure that the containers that come in here are recovered as much as possible. So you dont know what happens to the plastic that you recover once youve given it to the broker . Well no, but from what we understand there is a local market for that but for the most part a lot of the material is shipped overseas mostly to the asian pacific. In 2014, the secondary plastic market sent about half of californias plastic trash to china. Because its a mix of all the different types of plastics, it can only be melted down or repurposed, a process known as downcycling. It could be tshirts, it could be teddy bear stuffing, it could be carpets. Cuz downcycled products end up on landfill, dont they, eventually . Ya they just take a longer trip before they eventually end up in a landfill. And theres another inherent problem with single stream recycling. Half of the country has access to recycling, and the other half might have a drop off program that might be nearby or it might be 10 or 20 miles away. In the u. S. Were able to use about 5 to 7 percent Recycled Content in pet beverage bottles in the United States. The number in germany, is 25 to 35 percent. In the us, bottle bills are rare. California is only one of six states that places a redemption value on noncarbonated pet bottles. Why dont we have a National Bottle bill, because it seems to be so successful . Sure, its purely for political reasons. But when plastic bottles are purchased in california, consumers pay anywhere from a nickel to a dime deposit on them at check out. We see about a million and a half customers a month. Canadian based company replanet with 700 locations in the u. S. , offers a plastic buy back program. Theyre a sort of middle man in the plastics trade. They redeem bottles for deposit. The result is dramatic. The recycling rate in california is typically three times higher than that of the rest of the nation. Here at this replanet sorting facility they process over two million bottles a day. Packaging up the best quality pet. These mountains of plastic are pressed. Prepped and then bailed. Among the buyers for this bailed pet. Is carbonlite, a 220thousand square foot plant, where they transform used plastic into material for new bottles. As a mechanical engineer, i feel like a kid in a candy store. Its very hot you cant touch it. Bails brought here are broken and the plastics are separated from any debris and then washed in hot water. Our second stage washes it very clearly, separates the caps and labels from the pet bottles. Its then separated into clear pet. Green pet and non pet. The clear and colored pet is ground into flakes. And washed again. Heated. Then melted. And then becomes pellets. Its called 1to 1 or bottle to bottle recycling. The plastic from one bottle is used to make another. Nothing ends up in landfill. They even recycle the labels and caps. Nestle waters and pepsis naked juice are among the companies heavily vested in 1to1. So if we get the recycling rates high enough in the u. S. Its very easy to have 100 percent recycled material for our use. If you keep something in closed loop, youre replacing virgin resources over and over and over again, so the math catches up with you in a pretty awesome way and is responsible for avoiding a whole bunch of environmental consequences. Coming up, a controversial landfill. The whole milpitas is like a huge bathroom, you know, it so smells, just smells so bad. Could Swedish Technology have the answer . We want to hear what you think about these stories. Join the conversation by following us on twitter and at aljazeera. Com techknow. Throwaway living. A promise of liberation. Americans are free at last. This feature in life magazine from 1955 signaled the beginning of a throwaway society. If people only knew the problem that they were creating when they extolled the virtues of throwaway living. This is a monster in the creating right here. Hello. Hello. Hi, my name is jennifer. Do you know about the newby island dump. They want to expand it. Have you experienced odors . Oh constantly, for years. These neighbors are talking trash. As a group of milpitas, california, residents go door to door to fight the expansion of the newby island landfill. Located in the neighboring city of san jose. They hold weekly meetings. It stinks and they host town halls. There is a significant odor that comes from the newby island facility. Sometimes you know when i just go out and take a walk i just feel dizzy, and i feel like throwing up. The whole milpitas is like a huge bathroom, you know, it just so smells so bad. Milpitas, california. A sleepy Bedroom Community is the gateway to silicon valley. A bustling tech town of 70,000. Many citizens here say the garbage is taking over and ruining their quality of life. Im a Real Estate Broker and years ago, very few people would ask about odor. Now 100 percent of the people that are buyers within the community are asking about the odor. That is going to affect property values. Newby Island Resource Recovery park here in san jose, is a landfill operated by republic services, the nations second largest Waste Management company. Its been taking trash since 1930 and was scheduled to close in 2025. Instead today, the city of san jose is not only planning to keep it open until 2041. They want to grow it from 150 feet above sea level to 245feet. Increasing its capacity more than 15 million cubic yards. We failed and didnt stop this expansion, um, i want to move out of this area. Americans create about 250 millions tons of trash a year. In 1988, there were about 8,000 landfills in america. Two decades later, that number dropped to below 2,000, spurred on by environmental and health concerns, heavily Populated Areas started closing landfills and shipping trash to more remote regions. San francisco hauls its trash about 50 miles across the bay. New york city trash is trucked out of state. To new jersey, pennsylvania. Even as far away as ohio, virginia and south carolina. And until recently, america was doing a brisk business, selling its scrap to china. But now, even china is leery. Times have changed. The awareness of the public is much greater about Health Issues now than it was when newby began. Newby is one of the largest active landfills on the shores of San Francisco bay. I dont think it should smell like this in america. The city of milpitas filed a lawsuit against san jose over environmental impacts caused by the landfill. The bay area air Quality Management district, which has received 2,000 newby landfill odor complaints has issued newby island five public nuisance violations related to odor issues. According to a district spokesman, they are still negotiating the fines. Trash is a big business and unfortunately its a smelly business too. Don litchfield, the Northern California environmental manager for republic services. The community itself seems to have some concerns about this site and the odor problem that theyre experiencing. Unfortunately weve been a little slow to address those concerns so wed like to apologize to the community for that. Here at the landfill weve had an odor mitigation plan that weve been working on for years. We get a lot of fresh refuse that comes in every day and we have odor misting stations set up in strategic locations throughout the landfill that can mitigate some of the fresh odors. In addition, republic says it invested heavily in this stateoftheart recycling facility to help divert Landfill Waste. All of the material that we accept, over a thousand tons a day from the bay area, in california, comes into this facility and we divert it from the landfill. So we process the material and remove everything that is recyclable. So what is the output of this facility . 200,000 tons a year are being diverted out of landfills. Our output is 400 tons of paper, 30 tons of plastic, 90 tons of glass and 30 tons of metal every day. Despite diverting nearly 50 percent of their annual waste, the landfill is still growing and that causes some to look toward another possible solution. In sweden, a country that boasts 33 incinerators, trash is burned to create fuel in whats known as waste to energy. About half of their waste is recycled, and the rest is burned. Less than one percent goes to landfill. Sweden is known as a world leader in wastetoenergy incinerators like this one, which utilizes modern technology to capture and control emissions. San francisco authorities tell us, they have no plans to build an incinerator in the bay area. Instead, they say, they plan to increase composting and to continue to ban what they call bad designs. What is your hope for San Francisco . What were trying to do is really break that addiction to plastic water. San francisco is the first city in the country to ban the single use water bottle from city property. In the case of our ban on single use plastic Water Bottles, the goal here is to establish a marker, to lay it down in San Francisco, to work with other cities to do the same. In the meantime, however, were still a consume and dump nation. Republics landfill manager, Augustin Moreno says he wants residents to know just one thing as someone that works in trash for a living, and you hear the concerns of the citizens of milpitas, what do you have to say to them . This is not a dump, you know, you hear that word very often and for us, you know, we work here every day, its not fair to call this a dump. This is a modern sanitary landfill. We take pride of what we do here. These residents say they just wish they were doing it somewhere else. So its not that im fighting for my backyard, im fighting for the entire bay areas backyard. Nobodys backyard is going to be spared. Coming up next. Were standing by a pipe thats labeled, heated sludge. Mountains of trash piled high as the eye can see at this landfill just outside San Francisco. But inside this mass, scientists see potential. Some of this waste is organic about 40 percent of Landfill Waste nationwide is from food, thats waste that doesnt have to be there. But innovators are tackling that waste. A program that takes food from restaurants, vineyards and farms in the area. Turns that waste into energy. Were finding new ways to reuse what we used to call waste. Right now, im at 90 percent of the Waste Recycling and composting. Gabriella lozano owns a small cafe in San Franciscos mission district. She composts everything. Im a strong believer that im doing what i can, and the best that i can. What shes doing here on a small scale. Is part of a much bigger picture. You look at what shes doing here in terms of diverting waste away from landfills and creating a recycling type of circuit here with everything that happens at ls and thats what we have to look to. Inspired by western europe, San Francisco offers owners like lozano financial incentives to compost. A lot of these Small Business are actually doing it for economic reasons. It lowers their bill for recycling, their garbage bill over all. Money is a way to motivate people. But its not the only motivator. When the food waste is in the landfill it decomposes, and it generates methane gas and methane is a very potent greenhouse gas. John hake is a Civil Engineer who runs the Resource Recovery program in the east bay, where they combine solid food waste with liquid wastewater to create fuel. It has an odor it smells very organic. Yes, thats the term we use to describe the smell. Its like a black gold. Black gold . The process works like this food waste from throughout the bay area is trucked here to the east bay municipal utility district, or east bay mud, a Sewage Treatment plant and a pioneer of green power. Were the first plant in north america to become energy neutral and ultimately energy positive. When we started the truck waste program, east bay mud produced about 40 percent of the energy we needed to run the plant, and thats pretty typical for a waste Water Treatment plant. Today, were at 130 percent of our demand and that allows us to sell that excess Renewable Energy to the port of oakland, our neighbors next door. Im a little apprehensive, were standing by a pipe thats labeled heated sludge. The heated sludge is going into an anaerobic digester. A digester is like the human stomach, so organic material goes into the digester and in there its biodegraded by bacteria and they feed on the solid material and that solid material is being converted into biogas and that biogas is a great Renewable Energy source and its a fuel that we use to run our engines and turbine to generate electricity. Let me this get straight i eat a bunch of food, and i take the energy and fuel that i can from that and then it goes into the sewer system and you collect that and youre giving it to bacteria thatre turning it into energy. Thats correct. Each digester here is about two million gallons and we have 11 of them so thats 22 million gallons of capacity. East bay mud shared the technology and now other Water Treatment facilities in brooklyn, new york, and in california cities of marin, thousand oaks, fresno and san diego are using it. Most of us dont think about the waste whether its flushing the toilet or throwing things in the garbage. It just kind of disappears and i think as a society weve been very successful at sort of hiding where the waste goes and i think as time goes on and population grows and waste generation grows, then weve become more aware of waste generation and the things that we need to do to handle it. For me, i feel its a great responsibility not to leave such a big impact in the city, and in the world for the next generation. So through all of this its clear there is a problem out there with recycling, with way too much trash so what can we do as consumers . Some people think its an individual choice. We just need to get better at sorting our trash and sorting our recyclables and actually following through. Others think that we need to be taking a legislative approach. I mean San Francisco, theyve banned Water Bottles on Government Property and maybe we can do more things like that. When i work in latin america, glass bottles are the norm there. That is what you use whenever you get a soda from a restaurant or something but the difference there is you are expected to return that glass bottle to the person and they recycle it. Lots of times theyll give you a quarter in return but if you dont return that glass bottle, you are being very rude. Its like a societal norm that you are breaking. I think as consumers we need to be extremely mindful of not using plastic once so just try and increase the times you use packaging and then just make sure you trash it in a blue bin once you finish with it. When it comes to responsible use, i mean, also you think about whether or not you are putting it in the blue bin at all. I mean a lot of people just have this idea, im gonna throw it in the trash, im gonna throw it in this bin and then whatever it is is just going to disappear into the ether and then im absolved of all responsibility but it has to go somewhere, i mean conservation of mass if nothing else. It really did make me more aware of how much plastic im actually using, when i use a plastic straw or plastic cup. Any of those things because it seems there are so many of them we just use them once and throw them away and thats the end of it. Absolutely, there is nothing like standing at the open face of a landfill and going through your head of like well i threw away that yogurt container and then i had a water bottle this morning and my cups probably in there and you really start to realize how much of this waste you generate in a day. I am sure you can see it and you can smell it. Yes, it doesnt smell too great. Well guys it was certainly a dirty job but an important one to tell so thank you for bringing it to us.
