Nexus is the first company to offer a truly turnkey modular anaerobic digestion appliance for the agriculture, food and beverage industry. Our Bio1 process digests solid waste in a compact footprint with no waste water produced. Since there is no cost to dispose digester wastewater, the Bio1 systems have significantly lower operating costs compared to competition.

Nexus offers zero-wastewater anaerobic digesters in formats for a full range of applications for organic waste processing. Standard anaerobic digesters require lengthy on-site construction with significant project risk. Nexus's turnkey design is delivered as a preassembled unit that is ready to produce biogas in just a few weeks.
The Nexus Bio1 system can accept most types of solid waste including
- Dairy, cattle manure
- Poultry house droppings and bedding
- Meat processing waste including paunch
- Food waste
CUSTOMER BENEFITS
For food processing plants the Nexus Bio1 systems provide 10-20% operational savings through
- On-site generation of renewable power
- Elimination of off-site trucking and disposal charges or
- Elimination of on-site composting labor
- Revenue from fertilizer and compost sales
The Bio1 system is a full solution to implement sustainability and environmental compliance. Waste can be loaded into the modules as soon as it is produced where it is processed in a enclosed, air-tight container. This minimizes odor and nutrient run-off and improves compliance with state and federal regulations.

Biogas from the Bio1 process is combusted in a turbine to generate electricity and steam or hot water from the turbine exhaust (cogeneration). This combined system is highly efficient and captures 60-70% of the heat content of the biogas.
For commercial and industrial customers the Nexus system takes advantage of net metering laws in most states. Customers can generate on site power (from any source) and push the excess power into the grid and to draw from it when their own power capacity dips. Unlike solar panels, the Nexus system generates renewable energy at a constant rate 24/7.
