Plastic waste solution- conversion

Plastic is one the greatest invention of human history. It brings us benefits of low cost, durability and easy formation, meanwhile it causes us problems of climate impact by generating carbon emissions and pollution to our environment due to its durability.

The plastic waste problem has long been one of the most critical concerns for many countries. Some may have restrictions for production and importation, and others may propose incentives for the recycling, reusing and conversion of plastic products.

Trend

The production and use of traditional building materials contribute to environmental pollution and natural resource depletion. Besides, disposal of agricultural, industrial, and construction waste and other solid wastes is a significant contemporary for both developing and developed countries.
Developing conversion technology of turning waste into construction materials is getting more and more attention nowadays.
With many years experiences and special development team with all elites from many different countries. We have significant breakthrough in constructions material with recycled plastics composite.

* The 3 million tons of plastic waste discarded in Canada every year includes single-use plastic bags, containers, bottles, etc. .These plastic wastes may cause harm to wildlife and contribute to ocean pollution. Governments and environmental groups are working hard to promote recycling policies to reduce the amount of plastic waste .

* The Canadian government has officially banned companies from importing or producing plastic bags and takeout boxes starting in December 2022 .
In addition , starting from the end of 2023 , these plastic products will no longer be sold in the country

By the end of 2025 , not only will they not be produced or imported, but all of these plastic products in Canada will not be exported to other places .

* Canada ’s goal is to achieve “ zero plastic entering landfills, beaches, rivers, wetlands, and forests ” by 2030 , so that plastic disappears from nature . . In addition to plastic bags and takeaway boxes, the ban also applies to single-use plastic straws, stirring sticks and knives, and six- pack cans or water bottle holders .

Canadian government aims to reduce plastic pollution and protect the natural environment and wildlife .

Although some plastic manufacturers have expressed opposition to the case, the policy is seen as an important milestone .

Plastic Recycling

Common plastic recycling sources

PCR-Post-Consumer Recycled
consumer recycling / end of life cycle

PIR-Post-Industrial Recycled
Industrial waste / leftovers / NG material

Wood plastic composite

Wood ( wood powder ) + Plastic = Composite

Plastic wood composite materials are made by grinding waste wood raw materials into powder .
The waste plastic ( thermoplastic plastic ) raw materials are then pulverized and kneaded to form a composite material .Usually called WPC (Wood Plastic Composite) .

Common type of material compounds application in construction material

1.Wood powder + plastic

2. Fiberglass + plastic

3.Stone powder + plastic

4. Metal + Plastic

When the two materials are mixed , it will not be recycled and reused, which is not in line with the ESG spirit .
