Waste Plastic Pyrolysis Technology Contributes To The “Zero Waste City”

Waste plastic disposal is an important part to build “Zero Waste City”. Zero Waste City is a new model of urban development. It is launched according to the new development concept of innovation, coordination, green, openness and sharing. The purpose is to encourage people to establish green development methods and lifestyles, promote the resource utilization of solid waste, minimize the amount of landfill, and minimize the environmental impact of solid waste.

“Zero Waste City” does not mean that there is no solid waste generation, nor does it mean that solid waste can be completely recycled, but hopes to finally achieve the goal of minimizing the generation of urban solid waste, fully utilizing resources, and safely disposing of it. This requires our long-term exploration and practice.

How To Deal With Urban Waste Plastic Pollution?

Waste plastic pollution is present nearly in every city. The public is increasingly concerned about the ecological and health hazards posed by the accumulation of plastic waste in communities, parks and beaches.

The pollution of water and food by plastic is tend to be a blind spot in urban sanitation system and waste disposal that cannot be addressed in the short term. This has sparked thoughts on how to isolate this ubiquitous synthetic material from the environment .

At present, global plastics production is still growing at a relatively fast pace, while at the same time the negative impact of plastics on the environment is increasing. Our relationship with plastic needs to change fast.

To address the environmental problems caused by the development of plastics, many countries have proposed plastic reduction (including saving raw materials and reducing the amount of waste plastics) as the preferred way. Focusing on recycling as a priority orientation and degradation as a complement to recycling is driving the harmonization of plastics and the environment.

Since 1950s, 8.3 billion tons of plastic have been produced worldwide, among about 60% of which end up in landfills or exposed to natural environment. Plastics are playing an important role in packaging food, beverages and other products in a safe and secure manner. However, to protect the planet and meet the growing needs of humanity, we need institutional change. Of course, the key is release the reply on plastic and find more sustainable products.

Technical Analysis Of Waste Plastic Disposal Methods

The recycling of waste plastics is one of the topics that people have been concerned about. It can turn industrial waste into valuable industrial production raw materials and realize the recycling of resources, which is of great significance that cannot be ignored.

The recycling technology of waste plastics can be divided into three main categories, namely, mechanical recycling technology, chemical recycling pyrolysis technology and incineration recovery technology.

Mechanical recycling technology is to process and mold the recovered plastic products directly by identifying, sorting, cleaning, crushing or dissolving, and melting; or after chemical modification, then processing and molding. With the existing technology, i.e. mechanical recycling by crushing and remelting, it is not applicable to all plastics and there are limitations in the production of food grade recycled plastics.

In some cases, scientific chemical recycling is the best way. In chemical recycling of waste plastics, the development of waste plastic pyrolysis technology has solved many technical difficulties in the chemical recycling of waste plastics, and realized the large-scale industrial application of chemical recycling of waste plastics.

Unlike machanical recycling, chemical recycling transforms hard-to-recycle plastics (including post-consumer flexible plastic packaging and other mixed, degraded or contaminated polyethylene and polypropylene plastic waste) into new food-grade plastics that comply with European regulations. What this technology changes is molecular structure of plastics, which is broken down into molecular structural units. CGF has released a Chemical Recovery Life Cycle Assessment report that examines the positive environmental impacts of pyrolysis technology (the most mature chemical recovery technology) over a fixed time horizon.

A review by experts from the United Nations Environment Programme, research institutions and the private sector showed that in Europe, greenhouse gas emissions from chemical recycling are 43% lower than those from incineration.

Above all, the key to solving the plastic crisis lies in whether waste plastics can be properly disposed of by environmentally friendly, scientific and economical chemical means, enter the resource cycle and be reused.

The Development And Prospect Of Waste Plastic Pyrolysis Technology

Industrial continuous waste plastic pyrolysis production line is one of the most advanced chemical recycling equipments.

Generally speaking, it has the following four merits:

1. No need to sieve plastic mixtures of different materials.

This pyrolysis plant has wide adaptable of raw meterials, which can process mixed plastics, reducing the complexity and cost of sorting.

It can be will reflected in Thailand waste plastic pyrolysis projct of Niutech.The local level of waste disposal and sorting is still in its development stage. The pyrolysis technology is a good solution to this shortcoming, successfully converting waste plastics into high-value fuel oil.

2. Improve waste plastic recycling rate.

Waste plastic pyrolysis technology can handle waste plastics that are difficult to physically recycle, such as films, food packaging other small-sized industrial waste plastics. Relative to physical recycling, the plastic recycling rate is substantially increased.

3.  Achieving high quality recycling of waste plastics.

Pyrolysis process is to decompose the polymer in plastic into small molecules or monomer state, which in turn produces fuel oil, solid fuel, etc.

4. It can reduce greenhouse gas emission.

Plastic waste in the city has always been a difficult point for plastic recycling and disposal. And waste plastic pyrolysis technology and equipment developed by Niutech is a good solution to the problem of low-value waste plastic disposal. Some waste plastics that are difficult to physically recycle, including plastics containing food residues, multi-layer plastic packaging, and composite plastics used in the automotive and construction industries, can be effectively disposed of and achieve good economic and environmental benefits.

At present, the pyrolysis technology of Niutech has been widely cooperated with many regions around the world, such as BASF, Saudi Basic Industries and many other energy and environmental giants.  For the city’s plastic waste, if we can turn potential pollutants into higher value products, there is no doubt that this is also making a proper contribution to the environmental protection of the earth.
