Reduced waste handling and disposal costs
By eliminating food waste storage and transportation, the LFC biodigester helps commercial kitchens reduce their carbon footprint, improve kitchen hygiene, and comply with modern sustainability and ESG requirements. It supports zero-waste kitchen concepts, lowers operational costs, and enables long-term sustainable catering operations.
A food waste processing system (biodigester) helps eliminate bad smells by processing food waste continuously on-site instead of storing it in bins or containers. By breaking down organic waste in a controlled, enclosed system, it prevents food from decomposing in open air, which is the primary cause of unpleasant odours in kitchens and back-of-house areas. This leads to a cleaner working environment, improved hygiene standards, and fewer complaints from staff, guests, and neighbouring businesses. For professional kitchens, it also supports better compliance with health and environmental regulations while maintaining a more pleasant and professional atmosphere.
Restaurants should manage waste food in a way that minimizes environmental impact, maintains hygiene, and complies with local waste regulations. Best practice includes separating organic food waste, reducing storage time in bins, and using on-site food waste processing systems that safely handle organic waste as it is produced. This approach helps reduce odours, pests and waste collection frequency while supporting sustainable and environmentally responsible restaurant operations. With LFC bio-digester you can turn your waste food to environment friendly gray water.
The LFC food waste processing system (biodigester) is designed to handle most common types of organic food waste generated in professional kitchens. This includes fruit and vegetable scraps, cooked and uncooked food, meat, fish, dairy products, bread, rice, pasta and plate waste. Processing food waste on-site helps reduce storage, odours and pest attraction while supporting environmentally friendly and sustainable kitchen operations.
It can decompose most food waste within about 24 hours, depending on the type and volume of waste being loaded.
Yes. LFC biodigesters are commonly used in high-volume facilities such as hotels/resorts and healthcare food service where hygiene, compliance and sustainability matter.
The system is designed for continuous operation where decomposed material exits as grey water, reducing the need for handling full food-waste bins. The output is grey water that is intended to be safely discharged to the sewage/drain system.
Choosing the right size food waste processing system (biodigester) depends primarily on the daily amount of food waste generated, the number of meals prepared, and the operating hours of your professional kitchen. Hotels, large restaurants, catering facilities, and hospitals typically require higher-capacity systems that can handle continuous loading during peak service periods.

The LFC biodigester uses a series of processes in which microorganisms break down biodegradable material in the presence of oxygen.
A medium inside the LFC biodigester — Powerchips — houses the microorganisms. In combination with our proprietary mixture of microorganisms and enzymes — Powerzyme — the digestion of food products is accelerated. The output is grey water that is environmentally safe. You discharge this down the drain or use it to enrich your landscape.
The process operates aerobically — in the presence of oxygen — so there are no smells. A motor turns arms inside the LFC drum to mix the waste with oxygen and microorganisms. That turning is only a quarter of the time and is slow to ensure that the waste is not macerated and allows the microbes to digest the waste.
A food waste processing system (biodigester) helps significantly reduce pest problems in back alleys by eliminating the need to store food waste in bins or containers outdoors. When food waste is processed on-site and continuously broken down, there is no accumulation of organic waste that attracts rodents, insects, or birds. This reduces odors, spills, and overflow that commonly occur around waste areas, improving overall hygiene and compliance with health regulations. For restaurants and hospitality venues, this results in a cleaner back-of-house environment, fewer pest control interventions, and a more professional appearance of service areas.
Supporting Green & Zero-Waste Kitchens
By processing food waste continuously with microbial digestion and oxygen enrichment, the LFC biodigester helps hospitality businesses achieve sustainability goals, lower carbon footprint, and comply with green waste management regulations — all while improving overall kitchen cleanliness and hygiene.
The effect of this on global warming is huge, because the largest part of garbage from catering and hospitality industry is waste food. Further, the decomposition smells and can cause health problems. Discarding 100 kg of waste food per day causes the equivalent of 153 tonnes of CO2 per year to be sent to the atmosphere.
Ideal for large-scale catering, hotel kitchens, and hospital food service operations, the LFC biodigester supports zero-waste initiatives, reduces waste handling costs, and enhances operational efficiency through uninterrupted food waste breakdown and real-time waste reporting.
