The method of turning plastic waste into electricity surprises the world

Scientists at the University of Chester (UK) have devised the first method in the world to turn plastic waste into fuel for cars and homes.

Breakthrough technology

According to Dailymail, they focus on non-recyclable materials such as food covers or plastic items thrown away on the beach.

They hope to turn these resins into eco-friendly electricity and hydrogen fuel without leaving any plastic behind during the conversion.

The scientists claim this is the first time they have found a recycling method that can be applied to any dirty plastic and leaves no residue behind.

The process involves gathering mixed, dirty plastics into strips of 5cm length, then melting in a 1,000 degree Celsius furnace. This furnace will immediately melt the plastic and gasify them. The gas produced in this process is called synthetic gas. This gas has very low CO2 content. The amount of gas is transferred into an industry standard system called pressure-transfer converter (PSA) to separate hydrogen with a capacity of 2 tons / day. The rest of the gas is used to generate electricity by generators. Electricity in this process will be a byproduct of hydrogen.

Scientists hope the patented technology will soon be able to power not only the 21-hectare plastic recycling plant in Ellesmere Port (Cheshire) but also 7,000 homes in a day, while simultaneously providing Hydrogen fueling 7,000 cars in two weeks in the UK.

University of Chester scientists collaborated with British company PowerHouse Energy to launch this plastic recycling initiative across Asia to remove plastic from oceans and beaches around the world. PowerHouse Energy said the Japanese Government was very interested in this initiative.

Professor Joe Howe, Executive Director of Thornton Energy Research Institute at Chester University said: “This technology converts all plastic waste into high quality, low CO2 gas that can be used to power generators. . The byproduct of the process is electricity, which means that waste plastics not only provide fuel for cars but also help to light up homes. Certainly the world will be surprised with this technology. It will make plastic waste valuable because it can supply electricity to towns and cities around the world. And most importantly, it can help wipe out waste plastic in the oceans. ”The process involves gathering dirty, dirty resins into 5cm long strips, then melting in a 1,000 degree Celsius furnace. will immediately melt the plastic and gasify them.

For the past two years, this innovative method has been tested through a sample furnace at Chester University. Next spring, scientists will build a large incinerator at the Protos factory in Thornton Science Park, Ellesmere Port.

This efficient conversion system will then be deployed throughout China, India, Japan, South Korea and Southeast Asia to clean up waste plastic. The plant will buy cheap plastic waste for $ 50 / ton.

Mr. Howard White, Vice President of Waste2Tricity, the exclusive licensee to develop this technology in the UK, Japan, Korea, China and Southeast Asia, said: “We will find solutions for the problem. world plastic problem when we can end the plastic source in China, India and Asia – the region that releases 90% of the plastic into the ocean. Clearing the ocean is great, but we need to prevent plastic waste from entering the ecosystem. The University of Chester team of scientists helped us develop this technology and it will soon be applied on a large scale to eliminate huge amounts of plastic in the oceans, and produce cheap hydrogen, low CO2 to as fuel for the future ”.

Plastic waste problem

According to the United Nations Environment Program Report 2018, every year the world uses 500 billion plastic bags and about 40% of the plastic produced for packaging. The amount of plastic waste is enough to surround the Earth 4 times.

Globally, about 5,000 billion plastic bags are used every year, with 1 million plastic bottles every minute being purchased and 90% of plastic bottles containing plastic particles. It is estimated that in the next 10-15 years, total global plastic production is expected to double. It takes hundreds of years, even thousands of years, the waste from plastic and plastic to decompose.

In those hundreds of years, they hindered the growth and development of plants and animals, clogged the infrastructure for people’s livelihood, narrowed the living space of the organism and poisoned the environment. Waste plastic and plastic when burning will create emissions containing Dioxins and Furans, which are toxic substances, lasting in the environment, directly affecting human health.

Plastic is an integral part of the economy, low cost, outstanding performance and durability; used in all industries, mainly in packaging and packaging industries with 40%, construction 20%, cars 9%, electricity and electronics 6%, agriculture 3%.

Total plastic production has increased from 1.5 million tons / year in the 1950s to over 380 million tons / year today. Global plastic waste management remains poor with only 9% recycled, 12% incinerated and nearly 70% buried or disposed.

Plastic waste causes waste of materials and energy loss due to the cost of 80-120 billion USD / year of value of plastic / plastic packaging materials; 6% of global oil consumption is used to make plastic products and will increase to 20% by 2050. More than 150 million tons of plastic exist in the ocean.

Each year 8 million plastic waste from the land is dumped into the ocean. Without action, the total amount of plastic poured into the oceans would probably double by 2025.

Losses of more than US $ 13 million per year for marine ecosystems, over 600 marine species have been affected, 15% are threatened; impact on tourism, fisheries, transportation, livelihoods and the threat to human health.
