SAFE RECYCLING OF BIOSOLIDS TO FARMLAND (UK)

Cambi cake is at the crossroads of strategic planning of biosolids

Capital expenditure and operating costs directly linked

to cost of tonne of water evaporation (tWE)/disposal

Drying makes no sense for agriculture at most transport

costs –only if agriculture option is not available

Digested cake to agriculture based on stackable safe, non smelly , low volume product –

it’s a transport business

Digested cake

No agriculture

Landfill – normally much more

expensive than agriculture

Top 4 Reasons for Cambi

• Reduced Capital Cost • Cambi is less expensive than new

digesters

• Cambi likely less expensive than digester

refurbishment

• Reduced Operating Cost • Dramatic decrease in biosolids leaving

the plant + Class A

• Integrates well with on-site power and

use of heat from engines

• Reduces GHG emissions • DC Water 40% reduction in GHG

• Provides Security for Solids

Handling and Cost (Reduces

Risk) • Known and predictable capital and

operating cost

• Reduced volume of solids

• Class A product allows for more options

• Eliminates the risk of rapid (e-coli)

regrowth and odors

CAMBI ORGANIZATION

Founded in Norway in 1989, Cambi has today more

than 125 employees and representatives, local

offices in 9 countries.

Cambi’s headquarter is in Asker, (Oslo), Norway.

Cambi’s manufacturing site is in, Congleton,

(Manchester),UK

PRINCIPLES OF CAMBI HYDROLYSIS

Batch heat sterilization

Meets all known safety standards worldwide, USEPA alternate 1 time/temp Class A batch – no reactivation

Destruction of Extra Cellular Polymer – ECP

Sludge becomes compressible for dewatering (10% DS% gain) and less viscous (10% hydrolysed =~ 5% conventional)

Hydrolysis of insoluble COD

30-50% solubilisation enables very rapid digestion, 10 days HRT, 60% VSR

Steam disintegration of particulate matter

Increases digestion rate and reduces viscosity further

THE CAMBI VALUE PROPOSITION FOR MUNICIPAL SLUDGE AND ORGANIC WASTE

Reduce or eliminate residual

waste disposal. Recover nutrients and

produce Class A Fertilizer.

Generate clean,

renewable energy from

waste.

Cut greenhouse emissions

dramatically.

Save millions in annual costs for the

cities.

THE GREAT CITIES OF THE PRESENT WERE

BUILT AROUND NATURAL RESOURCES

THE GREAT CITIES OF THE FUTURE ARE

BUILT AROUND HUMAN RESOURCES

H U M A N R E S O U R C E S D E M A N D

C L E A N C I T I E S

For a City to remain great, it

needs to attract Human

Resources.

As cities attract more and

more people, a strategy is

needed for dealing with

Human Waste.

The sewer is the conscience

of the city

PEOPLE DEMAND CLEAN

WATER, AIR, AND CITIES.

THE CHALLENGE IS THAT PEOPLE GENERATE WASTE AND

REQUIRE INCREASING AMOUNTS OF WATER AND ENERGY.
