Compost is organic matter that has been decomposed and may be made from single source material or blended for specific application performance. Green waste materials uses include: garden debris, kitchen scraps, manure, or yard and lawn waste.
Nutrient rich in composition, compost acts as a natural, healthy, organic fertilizer for your plants. It is typically a soil additive mixed prior to planting to provide nutrients and improve soil structure, but can also be used a protective mulch layer or top dressed to planted areas.

Screens are very useful with compost because it helps provide the most consistent end product for consumer use and higher profitability due to reduced waste.
