THE GREEN LOOPBio-waste in – energy and ertiliser out

- recycling energy



The Ecopro plant

– converting bio-waste to energy & high-class biosolids

Cambi is a Norwegian

company specialising in

biological waste treatment

We design and build plants or treating biological waste

Every plant we deliver is based on our patented Thermal Hydrolysis Process (THP), a highly efcientand cost effective treatment process.

Cambi plants feed on organic waste, both from households and industry. And our plants are hungry:

High digestion rate and high dry solids improves the digester capacity.

Our projects comprise the whole range from preliminary studies and design to commissioning and start up.

In addition to turnkey plants, we also offer nanced projects (build, own, operate, transfer - BOOT, etc)and operation & maintenance contracts.



Bio-waste to energy and highclass biosolids/ertiliser

Cambi provides bio-waste plants,focused on maximising biogas production

and minimising nal product mass. Becausewaste quality can vary a lot, our systems aredesigned to handle most variations.

Our patented process meets all knownenvironmental requirements, including theAnimal By Products Regulation (ABPR,1774/2002/EC) category II & III materials.



The Cambi® Thermal Hydrolysis Process (THP)Cambi’s patented Thermal Hydrolysis Process (THP) treats municipal and industrial waste prior to anaerobicdigestion. Most conventional biogas technologies operates with 70°C. The Cambi process treats the organicmatter at 165-170°C, dissolving it into an easily digestible feed for biogas production by anaerobic digestion,while destroying any harmful organisms (pathogens).

The THP is highly energy-efcient with low operating costs. It also eliminates odour problems associatedwith the treatment of organic materials. The end product (digestate) – a pathogen free and pasteurised biosolids

– can be applied to land directly, composted or dried.



Signifcantly increased biogas production

All Cambi plants have closed systems to minimize allpotential smell/odour. The biogas can be used to producegreen electricity in turbines/engines, where exhaust heatis used to provide all or most of the steam needed in theTHP process. The biogas can also be upgraded and usedas renewable vehicle fuel. Higher digestion rate and highdry solids digestion (10-12% DS feed).

We know biological waste treatment

Cambi’s THP is designed to handle almost all types ofbio-waste. The process can also treat a wide variety ofbiological wastes, including categories II and III animalby-products. Cambi has already delivered a plant forhousehold waste and industrial food waste, and havesigned a contract for another one to be completed in 2008,both located in Norway. The thermal hydrolysis process isalso operating in 11 commercial sludge treatment plantsaround the world.

The main advantages o Cambi THP over

conventional anaerobic digestion



Material to be treated

Biodegradable municipal solid waste (source - separated household waste)

Organic residues from food processing industry



Slaughterhouse waste Other biological waste (agriculture)

Final productsPathogen-free nutritious fertiliser produced from biowaste can beused as a fertiliser in agriculture, or as an organic soil improver.

Project: Lillehammer-GLØR (www.glor.no)

Input/material to be treated:

Source – separated household waste and food waste from industrial sector.

Capacity: 14,000 t/a

Energy data: For every 1000 kg input, there is approx. 380 kg reject and 150 kg

of digestate. The plant makes about 300 kWh of electricity per 1000 kg of post-reject waste.COD conversion 68 % and VS conversion 70%.
