OUR TECH
Patented Thermochemical Liquefaction Process
Advanced recycling of plastic waste into petrochemical products which can be further refined into fuels, waxes, and new plastic production.
Receiving
A wide variety of plastic waste arrives from industrial and recycling factories ready to be fed into the system. Alterra has developed a large database of plastic waste material and process characteristics, which along with our thermodynamic and kinetic models, predict key system parameters and product quality.
Normalization
The plastic waste is fed into the pre-pyrolysis processor where it is heated, mixed with an additive and densified. This ensures the waste plastic is consistent for processing.
Depolymerization
The plastic waste is heated in the absence of oxygen until it breaks down into a condensable hydrocarbon vapor and noncondensable gas. Alterra’s pyrolysis vessel ensures predictable outcomes achieved under a controlled environment within the reactor system.
Condensing
The hydrocarbon vapor is then cooled into a liquid petrochemical product which can be further refined into fuels, waxes and feedstock for new plastic production. Noncondensable gas is routed back to the system for energy recovery.
Shipping
The product is shipped to customers, thus enabling the circular economy.
