Compost Screening Equipment in California


Greenrock Equipment stores various trommel screens and vibrating deck style pieces of compost screening equipment.

Our EDGE Trommel Screen is the market leader in Southern California and is fully adjustable to screen various sizes of organics material. The radial fines conveyor allows for the stockpiling of large volumes of compost. This allows the producer to market quality compost to farms and various growers.

Small scale producers providing for specialty markets, like Cannabis composting, can utilize our smaller EDGE TRT516.

If you are in California and you would like a resource to keep up with compliance with the SB1383 mandate, this is a valuable resource.

In a nutshell, the regulation sets out that:

“In September 2016, Governor Edmund Brown set methane emissions reduction targets for California (SB 1383 Lara, Chapter 395, Statutes of 2016) in a statewide effort to reduce emissions of short-lived climate pollutants (SLCP). The targets must:

Reduce organic waste disposal 50% by 2020 and 75% by 2025.

Rescue for people to eat at least 20% of currently disposed surplus food by 2025.”

This legislation has driven growth in compost production and redirected material away from the landfills.

Every facility producing compost needs reliable compost screening equipment. Thats where Greenrock come in. This is what we do. No compost is too wet for our industry leading screens and we will do our very best to keep your machines running so you can keep production consistent.
