Waste in - energy and fertilizer out
Cambi technology treats bio-material and produce renewable energy and fertilizer. With a thermal hydrolysis process prior to bacterial degradation, waste like sludge or bio-waste is desintegrated, sterilized and digested. The outcome is biogas that can be used to transportation or electricity, and fertilizer which can be used in agriculture.
BIOENERGY. Cambi technology treats bio-material and produce renewable energy and fertilizer.
Cambi's Thermal Hydrolysis Process (THP) is a proven and reliable technology that has been used around the world since 1995 in existing and “green field” projects to reduce both disposal quantities and the cost of building and operating digesters.
Improving the world’s ecological balance
The technology brings bio-material treatment to ecological balance. Cambi THP is a high-pressure steam pre-treatment for anaerobic digestion of municipal and industrial sludge and bio-waste. Applying THP technology results in doubled digester loading, increased biogas production, and a pathogen-free and stabilized bio-solids product with increased cake dewaterability. This saves both transport and energy costs, whether applying the end product directly in agriculture or drying it for fertilizer or bio-fuel.
The THP is highly energy-efficient with low operating costs. It also eliminates odour problems associated with the treatment of organic materials. The end product (digestate) – a pathogen free and pasteurized biosolids – can be applied to land directly, composted or dried.
Cambi THP plants can be combined with cogeneration plants, which produce green electricity and provide hot steam for the Thermal Hydrolysis Process. However, the biogas can also be cleaned to be used as vehicle fuel or as a replacement of natural gas.
Advantages
- Significantly increased biogas production
- Significant sludge cake volume reduction
- Higher digestion rate and 8 – 12% dry solids feed to digestion increases digester capacity two to three times
- Stable and reliable digester operation
- Highly energy-efficient process
- Eliminates foaming problems caused by filamentous bacteria (Nocardia, etc.)
- Sludge dewaterability improved up to 40% dry solids
- Pasteurized cake: Guarantee of pathogen kill (class A biosolids) with no regrowth or reactivation of bacteria
- All Cambi plants have closed systems to minimize all potential smell/odour.
Cambi creates value from
- Municipal and industrial sludge
- Bio-waste, including food waste and slaughterhouse residues
- By-products and waste from processing industry and agriculture activities
- Lignocellulosic feedstock
- Distiller's wet grains, thin and whole stillage
