What is The Best Compost Screening Equipment?
TROMMEL SCREEN VS VIBRATING DECK SCREEN?
Which piece of equipment is best when it comes to screening compost?

TROMMEL SCREEN FOR 2 PRODUCT SEPARATION
The trommel screen is the most popular equipment for screening compost. With a trommel screen, you will get 2 product separation – fines & overs.
VIBRATING DECK SCREEN FOR 3 PRODUCT SEPARATION
The vibrating deck screen is our suggested equipment for screening compost if 3 products are required. With a shaker deck screen, you will get 3 product separation – fines, mids & overs.

Our EDGE Trommel Screen is the market leader in Southern California and is fully adjustable to screen various sizes of organics material.

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.
