Getliņi EKO, the largest municipal solid waste landfill in the Baltic region, has developed a flagship example of internal industrial symbiosis by transforming landfill gas into a renewable energy source for modern greenhouse cultivation. By integrating waste management, energy production, and agriculture, Getliņi EKO demonstrates how circular economy principles can reduce environmental impacts while creating new economic and social value.
As a major landfill managing thousands of tonnes of municipal waste each year, Getliņi EKO faced the challenge of controlling methane emissions generated during waste decomposition. Methane is a potent greenhouse gas, and unmanaged emissions pose serious environmental risks. At the same time, the landfill needed to find productive uses for waste byproducts and respond to growing demand for locally produced, year-round vegetables in Latvia, ideally without increasing fossil energy use.
Getliņi EKO’s solution is based on capturing and utilizing landfill gas as a renewable energy source. Methane-rich gas is collected from the landfill body and fed into cogeneration units, where it is converted into heat and electricity. Instead of being flared or released into the atmosphere, this energy is redirected to support productive activities on-site.
A key application of the recovered energy is the operation of advanced greenhouses located adjacent to the landfill. These greenhouses use the heat and electricity generated from landfill gas to maintain controlled growing conditions, enabling the year-round cultivation of tomatoes and cucumbers. This creates a closed-loop system in which waste decomposition directly supports food production, linking environmental management with local agriculture.
The strength of the Getliņi EKO model lies in its circular integration. Waste management, energy recovery, and greenhouse farming are combined into one synergistic system, maximizing the value extracted from waste while minimizing emissions and resource losses. This integrated approach demonstrates how large-scale waste facilities can evolve into multifunctional hubs within a circular economy.
The impacts of this model are significant. Environmentally, methane emissions are substantially reduced through capture and reuse, while reliance on fossil fuels is lowered by substituting renewable landfill gas for conventional energy sources. From an energy perspective, continuous gas production enables self-sufficient heating and electricity supply for greenhouse operations. In terms of food security, local and sustainable vegetable production reduces dependence on imports and ensures a stable, year-round regional food supply. Operationally, the integration of waste management and agriculture improves efficiency and long-term sustainability. Publicly, Getliņi EKO is increasingly recognized as a leader in circular innovation, strengthening its credibility with citizens, policymakers, and institutions.
Key lessons from the Getliņi EKO case show that waste-to-energy systems can provide reliable inputs for energy-intensive agricultural activities. Integrated systems that connect waste, energy, and food production maximize circular value and resilience. The case also illustrates how visible green innovation can enhance public trust and policy support, while efficient resource use simultaneously reduces emissions and operational costs.
