Dewatering Food Waste with RUNI Screw Compactor

The installation of RUNI SK370 as a food waste compactor or as a machine for depackaging food waste reduces water content significantly, reducing the weight of the waste by more than 50%. Furthermore, a few extra percent of the organic material is collected from the waste and can be added to the "energy soup" for the biogas.

Producers of biopulp from food waste optimize their plants significantly with this solution, as they can reuse the dewatered water in their system and save money on transport and disposal of the remaining waste. Dewatering food waste also reduces both the volume and weight of rejects, saving you money on transportation and disposal.

The RUNI Solution for Food Waste

The RUNI SK370 screw compactor has proved to be a strong and reliable machine for many years. It is designed to work 24/7 with a capacity of processing 2000 kg of food waste rejects per hour. When dewatering rejects from food waste, RUNI typically achieves up to 50-65 % of dry matter.

FAQ

How does a food waste compactor work?

When handling food waste, the compactor squeezes the bio-liquid out of the reject to gain as much biogas as possible from the food waste. In the process, it significantly reduces water content, cutting the weight by over 50%. Operating continuously, it processes up to 2000 kg of food waste rejects per hour, optimizing biogas plant efficiency by minimizing water content, waste weight, and associated costs while maximizing bio-pulp output.

Is there any food waste you can not put in a compactor?

The food waste compactor handles liquefied food waste, usually together with packaging or plastic bags.
