Waste-to-Energy plant planned in Acone, Latvia
A planned modern facility to reduce landfill waste and support national energy independence
Gren provides district heating and cooling, renewable energy solutions, and industrial energy services. We have waste-to-energy experience, with a strong track record of delivering large projects and operating them with high efficiency, availability, and reliability. We provide reliable and affordable energy using local resources and work closely with communities and governments to support long-term energy resilience.
In Gren’s waste-to-energy plants, the remaining non-hazardous municipal and industrial waste that cannot be further recycled is used as fuel to produce electricity and heat in a controlled incineration process.
Our experience in Lithuania:
We have been supplying heat to the district heating company in Klaipėda since 2013, and in Kaunas since 2020. The heat is generated in our waste-to-energy plants using non-hazardous municipal and industrial waste. These plants recover energy for both heat and electricity production while diverting waste from landfill.
Waste-to-energy contributes to:
-
reduced volumes of waste sent to landfill, for waste that cannot be further recycled;
-
local infrastructure development;
-
competitive heat tariffs;
-
energy independence and security;
-
investment in the national economy.
A modern waste-to-energy plant developed by Gren, a Northern European energy company with experience in building and operating such facilities.
Location: Acone
Annual processing capacity: 150–200 thousand tonnes
Energy source: Sorted, non-hazardous waste that cannot be recycled; low-quality wood residues; other biomass residues
Origin of energy sources: Latvia
Thermal capacity: 50–70 MW
Electrical capacity: 15–20 MW
Heat produced: Equivalent to the annual needs of ~40,000 households
Project Timeline
The planned Waste-to-Energy plant will be located in an industrial development area in Acone close to Riga city.
Benefits for society
The planned Waste-to-Energy plant in Acone is expected to deliver the following benefits for society and environmental protection:
- A reduction of waste sent to Latvia’s landfills, with its energy content instead recovered for energy production.
- Energy production using sorted, non-hazardous municipal and industrial waste and biomass that cannot be recycled and would otherwise end up in landfills.
- Improved infrastructure and new jobs for the local community.
- Reduced landfilling and treatment of emissions in line with applicable environmental permits, once operational.
Economic benefits
- The investment project is expected to stimulate economic growth, create new jobs, and strengthen the country’s energy security and independence.
- Gren is committed to investing in the development of local industrial infrastructure.
- The Gren waste-to-energy plant in Acone is a private investment project that does not require additional state or municipal funding.
Development of Waste-to-Energy plants in Europe
According to CEWEP, in 2023 Europe had 499 waste-to-energy plants that convert non-hazardous municipal and industrial waste into electricity and heat. Every year, these facilities supply electricity to nearly 20 million people and heat to approximately 17 million residents.
