OSCA 75 — Compact, Flow-Through On-Site Composter
Turn everyday organic waste into nutrient-rich compost in 10–14 days with a small-footprint system designed for schools, cafés/restaurants, resorts and facilities that want lower disposal costs and greener operations.
Small footprint, serious performance.
The OSCA 75 is a continuous, flow-through composter that converts mixed organic waste into high-quality compost on site.

How it works
