Anaerobic digestion: Waste to energy for wastewater

Municipal wastewater treatment plants benefit from using anaerobic digestion (AD) to manage mixed waste streams and generate their own renewable natural gas (RNG) for heat and power generation (CHP). Excess RNG can be sold for injection into the gas grid to generate additional revenue.

Treatment of mixed waste streams in RNG production

Producing biogas through AD for wastewater treatment provides a long-term reliable solution to the treatment of mixed waste streams. Biogas for on-site electricity generation helps plants with energy self-sufficiency or provides back-up power resilience.

Support operational efficiency and decarbonisation

Anaerobic digestion for municipal wastewater treatment plants enables management of waste and generates renewable natural gas for power generation through CHP, for upgrading to biomethane for grid injection or liquefaction for transport use.

01

Desulphurisation of biogas

To prevent damage and ensure long life, H₂S must be removed from biogas for use in CHP engines. Biogasclean DS-BTR and DS-MBR desulfurization solutions are self-adapting with reliable H₂S removal. Biological in nature, the solutions operate with minimal supervision at a fraction of the cost of alternatives and provide further polishing for VOC and siloxane removal.

02

Biogas membrane upgrading technology

UPG-MS membrane systems are designed to produce high-quality biomethane for injection into the grid, liquefaction or CHP engines. Flexible modular system for use with CNG and LNG systems.

03

Bio-CNG and bio-LNG production

Compressing biomethane (bio-CNG) enables the storage and distribution of renewable natural gas for wider use. Biomethane may also be liquefied to bio-LNG for use in heavy road and maritime transport and industry.

Full gas value chain

Full renewable gas train solution covering biological desulphurisation, modular biogas upgrading to biomethane, CO₂ removal and liquefaction, biomethane to bio-CNG and bio-LNG systems, methanation, and gas polishing for fuel cell use to add maximum value. Fully supported by lifecycle management service and maintenance options.

Alcarràs Bioproductors

Working with Biogasclean has been a really strong partnership. They are strong on project execution, and they are strong on engineering.
Jeppe Baek

Project Innovation, Nature Energy.

Cycle0 was the best partner to carry out this project, especially due to its economic and technological scale.
Victor Toca Achurra

President, Toysal Group

What we have learnt is that responsible management of waste is possible. Here, we obtain clean energy that is directly injected into the grid, fertilizers that enrich the soil, all within a sustainable framework.
