Power from waste and biomass | Renewal in Geneva


Kanadevia Inova has signed a contract with Services Industriels de Genève (SIG) for the renewal of the waste-to- energy (WtE) facility at the Cheneviers site in Aire-la-Ville near Geneva, which entered operation in 1993. As part of the Cheneviers IV project, Kanadevia Inova will supply the new facility with two waste treatment lines. The new plant will have a total annual waste treatment capacity of approximately 160 000 tonnes. Each line will be designed to process 10.5 tonnes of waste per hour.


Two new boilers will each provide about 35.8 MW of gross thermal capacity, with an additional 10 MW generated by flue gas heat pumps.


A total of around 30 MWt will be available for Geneva’s district heating network. The existing von Roll Inova combustion and flue


gas treatment systems, in service for more than 30 years, will now be replaced by new technology.

feeding chutes through to the stack, including the associated cabling works. The current steam turbine will continue to be used and is therefore not included in the contract. The project will be carried out while parts of the plant remain in operation, requiring careful planning of the different project phases and efficient use of the available space. The Cheneviers IV facility will be constructed on the site of the Cheneviers II plant, which will be dismantled. Cheneviers III will remain in operation during construction and will be dismantled after the new facility has been commissioned. This phased approach will allow waste treatment operations at the site to continue throughout the construction period. The project is expected to take approximately four and a half years to complete.


Wood gasification in Asia: Spanner Re2


shows how


With a 2 MW waste wood gasification facility now in operation in Asia, Spanner Re² GmbH says it has reached a significant technological and economic milestone, with the project able to demonstrate the capabilities of modern wood gasification technology.


The plant incorporates Spanner Re²‘s complete system technology – from fuel drying and fuel preparation to power generation via gasification using 6 x 325 HKA 300 Pro units. Because of the presence of possible contaminants, the fuel preparation system

has been specifically enhanced with additional contaminant removal stages. This ability to reliably process challenging fuels


. In many regions of Asia, waste wood still has only limited economic value and, in some cases, is still disposed of in landfills. Spanner Re² technology transforms this resource into a locally available energy source, “combining resource efficiency, energy security and renewable electricity generation within a single concept.” The newly commissioned plant creates an important reference for future projects in the megawatt range, suggests Spanner Re².

METLEN achieves first fire on waste at Protos


Metlen reports it has successfully conducted first fire on waste at the Protos Energy Recovery Facility, which it is developing for Encyclis in Cheshire, UK.


Protos ERF, once fully operational, will have the capacity to process 500 000 tonnes of non-recyclable waste per year, generating up to 49.9 MW of baseload electricity. The process supports the circular economy, says METLEN, by recovering resources from household and commercial waste that remains after recycling (residual waste). As well as generating baseload


electricity, bottom ash from the combustion process is turned into secondary aggregates for construction and ferrous and non-ferrous metals are extracted for reuse.


METLEN has been acting as a strategic turnkey partner at the project, undertaking the design and execution on behalf of Encyclis, and in partnership with Standardkessel Baumgarte GmbH. The project was METLEN’s first waste-to- energy project and involved multiple technical challenges and complexities, the company notes. The first fire on waste at this complex project confirms the benefits of bringing the

former M Renewables and M Power Projects together under the single M RESET platform, says METLEN.


In a particularly demanding environment for the European construction and energy infrastructure sector, marked in recent years by material cost inflation, supply-chain pressures and increased challenges in delivering complex projects, METLEN says it “reaffirms through M RESET” that “it is one of the few companies capable of delivering complex thermal power projects with discipline and perseverance despite adversity.”
