How pyrolysis solutions fight ocean plastic pollution?

Ocean plastic pollution is one of the most pressing environmental challenges of our time. Every year, over 8 million tons of plastic waste enter the oceans, harming marine life, contaminating the food chain, and contributing to long-term ecological damage.

Pyrolysis is a thermal decomposition process. The plastic pyrolysis equipment designed by DOING R&D decomposes plastic polymers (such as polyethylene, polypropylene, and polystyrene) at high temperatures (typically 300-500°C) in the absence of oxygen into valuable products such as liquid hydrocarbons, solid residue (carbon-rich char or wax) and non-condensable gases.

DOING plastic pyrolysis technology

Here’s how DOING plastic pyrolysis equipment helps with ocean plastic pollution:

1.Stop plastic at the source

A significant portion of ocean plastic originates from land-based waste—mismanaged plastic trash that leaks into rivers, drains, and eventually the sea. DOING plastic pyrolysis equipment converts non-recyclable plastics (e.g., mixed plastics, degraded items) into valuable products. Instead of letting plastic waste pile up in dumps (where it can be swept into waterways) or burning it (which releases toxic fumes).

2.Environmental protection

Compared with landfill and incineration, pyrolysis technology minimizes the risk of ocean pollution:

No leakage: Landfills often leak toxic chemicals and microplastics into the soil and groundwater, and eventually into the ocean. DOING plastic pyrolysis equipment eliminates leakage by completely converting plastics into materials.

Environmental device of DOING plastic pyrolysis equipment

Low Emissions: Incineration releases greenhouse gases and toxic pollutants (such as dioxins) into the air, some of which settle into the ocean. DOING plastic pyrolysis equipment only produces exhaust gas, which is also equipped with an environmental purification device to ensure that emissions meet environmental standards.

3.Turn “unrecyclable” plastics into value

Only 15–20 % of collected plastic is mechanically recycled; the rest is too contaminated for conventional plants. DOING plastic pyrolysis equipment can process dirty, mixed or filmy waste (excluding PET and PVC) and convert it into pyrolysis oil that provides a lower carbon footprint for industrial boilers, generators, industrial feedstock, and renewable diesel; carbon black for construction or as filter media; and non-condensable gases for fuel.

4.Creating Economic Incentives for Cleanup

Input 1,000 kg of plastic to DOING plastic pyrolysis equipment, and output approximately 800–900 kg of pyrolysis oil, 100–150 kg of carbon black and 50–100 kg of non-condensable gas. These products generate a substantial profit, providing an incentive for cleaners and relevant departments to recycle ocean plastic waste. Here is a profit analysis chart from DOING research for your reference.

All in all, pyrolysis offers an effective method for recycling plastic waste. By converting waste into valuable products, it reduces ocean pollution, lowers carbon emissions, meets energy needs, and promotes environmental protection.
