Technology

Alterra Energy is the developer and operator of a continuous, thermochemical liquefaction process technology.
The best materials for the process are polyethylene and polypropylene, delivered in a shredded and dry state.
PVC and PET are not candidates for this process.
Preferred waste material is shredded/granulated to 2″ plastic piece size or smaller.
Chemistry must be such that the expected oil yield will be greater than 55%.
Waste will have a paper/cellulose component no greater than 20% – less is better.
Less moisture is better.

Feedstock that is not ready for the process comprises:

• #1 PET
• #3 PVC or any Chlorinated Resin, Chlorinated Polyethylene (CPE)
• Any Thermoset or Cross-Linked Polymers
• Any Fluoropolymers or Teflon
• Any Polyesters
• Chlorobutyl
• Fluoroelastomers
• Hydrogenated Nitrile Rubber
• Nitrile Rubber, Nylon.
