CAMBI

THE FOUNDER Odd Egil Solheim

Still testing out new ideas!

Biosolids:

Plants for enhanced biogas production from municipal & industrial

sludge

Biowaste:

Plants for biogas from source-separated organic waste

Biorenewables: • Biogas production from organic residues• Ligno-cellulosic biomass pre-treatment for bio-ethanol & biogas

Operations:

Cambi Operations provides support and operation services to

maximize plant performance

CAMBI’S BUSINESS AREAS

………………….TO A BRIGHTER FUTURE – WITH BIOGAS

(First prototype)

CAMBI THP PROCESS

BIOGAS PRODUCTION

The Dublin THP digestion plant ... can produce 3.5m³/day of biogas per m³ of digester

capacity, which is 350% of the normal situation.”

Dublin, Ireland

Conventional treatment CAMBI THP

CAMBI SIGNIFICANTLY REDUCES CARBON FOOTPRINT

”… installation of anaerobic digestion … significantly reduces carbon foot print, especially if dewaterability is improved” (Auty and Blake, 2008, Barber, 2009)

“… [The] thermal hydrolysis pretreatmentsystem at … Davyhulme … will reduce [United Utilities’] carbon footprint by 8% - the equivalent of removing 270,000 cars off the road for 30 years.”, March-April 2009, Worldwater

Benefits from the Cambi process

• Higher breakdown of material - produces more biogas

• Higher dewaterability – less cake with higher fertilizer value

• Higher digester load – smaller plant – smaller investment

• Sterilized sludge – can be spread on farmland

General project information• Employer:

– Vilniaus Vandenys, the municipal Water and Wastewater Company of Vilnius

• Contractor– Consortium WTE Wassertechnik GmbH/Cambi AS– Regarding the internal relations in the Consortium Cambi in reality acts as a subcontractor to

WTE

• Localisation of plant: Vilnius, Lithuania• Existing sludge treatment plant, will be modified and extended

• Total Project value: App 58 mill EUR

• Cambi Project value: 5.9 mill EUR

• Key dates:• Contract award: 03.11.2008• Detailed engineering completed: 30.06.2009• Restart of project: 01.10.2010• Start Cambi installation: April 2011• Construction complete:15.11.2011• Start up of THP: 15.01.2012

Scope of work- Consortium

• Develop and modernize the sludge treatment systems at Vilnius Waste Water Treatment Plant (WWTP)

• Sludge thickening, digestion, sludge dewatering and low-temperature drying as well as the utilization of the produced biogas in a combined heat and power station.

• After modernisation, plant will treat sludge from Vilnius WWTP and surrounding water treatments plants

• New sludge treatment system will be integrated in existing buildings

• Turn Key delivery

Scope of work - CambiTurn key supply of Thermal Hydrolysis Plant (THP) which includes:

• Thermal Hydrolysis Plant (THP)– 1 pulper, 5 reactors, 1 flashtank and integrated control system

• 3 sludge coolers– Heat exchanger and fin-fan coolers

• Design and engineering related to the supplied plant

• Installation of supplied equipment

• Commissioning of all supplied plant on water

• Training of operators

• Operating and maintenance manual

Experience from cooperation with Lithuanian companies

• Local company (RIFAS) is used for detailed design and installation of Control system and MCC.– Experience so far is good. (We do not know the conclusion until the plant has

started.)– Communication might sometimes be challenging due to missing English skills

among some of the employees.

• Local site representative hired through company Evikta– Evikta was engaged by WTE for construction application process– Experience is good– He is fluent in Lithuanian and English– Knowledge about local regulations– Personal/company authorisation is required for approval of installation work– Evikta is also used for minor mechanical modifications. Experience is good

with respect to quality and costs.

Experience from cooperation with Innovation Norway

• Innovation Norway was used for engaging the site representative

• Suggested potential companies that could offer the site representative service in addition to evaluation of companies suggested by Cambi.

• Prepared an evaluation of potential candidates

• Support during interwiev

• Support for writing the contract

Challenges related to the project in Vilnius

• Process for construction application– Detailed engineering (Technical design) had to be

completed for construction application.– A Lithuanian company (Evikta) prepared the

documentation for the application. – 5 months approval period for evaluation of the

application for Litianianian authorities was indcated at project start.

– The evaluation period was extended due to internal processes inside Lithuanian authorities

Future possibilities

• Sludge centers

• Biowaste plants

• Farm residuals
