Energy from wastewater
Unfolding the energy potential of wastewater and municipal sludge reducing grid dependency.
Energy recovery from organic pollution and sludge
We transform the challenge of wastewater into an opportunity for sustainable energy creation. Our state-of-the-art energy recovery solutions harness the untapped potential of organic pollution and sludge, converting them into valuable biogas. This innovative approach not only supports the environment by reducing greenhouse gas emissions and dependence on fossil fuels but also offers a cost-effective way to power your operations.
How does wastewater become energy?
Wastewater is converted into biogas, a clean, renewable energy source, through an eco-friendly and efficient process. Our technology harnesses the power of anaerobic digestion, where microorganisms break down organic matter in the absence of oxygen, producing methane-rich biogas.
This biogas is then captured, purified, and converted into electricity, heat, or biomethane, offering a versatile energy solution for industries and municipalities. Embrace sustainability, reduce greenhouse gas emissions, and achieve energy self-sufficiency with our innovative wastewater-to-energy systems.
Energy recovery from organic pollution and sludge
We are experts in recovering energy from the organic compounds in wastewater, organic waste, and municipal sludge.
In the food and beverage industry, we are the undisputed leader helping production sites to significantly cut down on the energy bill.
In the potato processing industry for instance, up to 60% of a potato processing plant's electricity needs is recovered from anaerobic digestion of wastewater and potato waste.
Recovering energy from wastewater
Diverse energy recovering systems are used to harness energy from wastewater, a cornerstone of sustainable environmental management. Our expertise lies in transforming wastewater into a valuable resource, not only safeguarding our precious water but also tapping into its latent energy potential.
Discover the various cutting-edge technologies and processes we employ to recover energy from wastewater, spotlighting the seamless blend of sustainability and efficiency that characterizes our solutions.

Energy from sludge: BIOTIM® Solids
Our BIOTIM® Solids sludge digester provides biogas while significantly reducing sludge volume. In the BIOTIM® Solids sludge digester, sludge is digested under mesophilic conditions. The recovered methane needs treatment before fueling the combined heat and power generation units.
Biogas desulphurization: BIOTIM® Scrubber
Biogas desulphurization is necessary to increase life duration of combustion engines. The BIOTIM® Scrubber uses activated sludge from biological wastewater treatment as a washing medium, omitting chemicals reducing costs for both water and chemicals.

Frequently asked questions
Why is energy recovery from wastewater important?
Energy recovery from wastewater is pivotal for several reasons.
It represents a sustainable method to generate energy, reducing reliance on fossil fuels and decreasing greenhouse gas emissions. This process not only contributes to energy self-sufficiency for wastewater treatment facilities but also aligns with global efforts to combat climate change.
By transforming waste into energy, facilities can mitigate operational costs and promote a circular economy where resources are reused and conserved. Energy recovery plays a crucial role in sustainable development, supporting industries in becoming more eco-friendly and resilient against energy scarcity.
What are potential environmental impacts of energy recovery from wastewater?
While energy recovery from wastewater significantly benefits the environment by providing a renewable energy source and reducing emissions, potential impacts must be managed. These include the need for careful handling of residuals from the energy recovery process, which could harm local ecosystems if not treated or disposed of properly.
Technologies used in energy recovery, such as anaerobic digestion, must be closely monitored to prevent any unintentional release of methane, a potent greenhouse gas.
Nevertheless, with appropriate management and technology, these impacts are minimal compared to the substantial environmental benefits.
Are energy recovery systems scalable?
Yes, energy recovery systems from wastewater are highly scalable. They can be adapted to serve facilities of varying sizes, from small community-based plants to large industrial operations.
The scalability allows for the customization of energy recovery solutions to fit specific needs and capacities, making it a viable option for diverse sectors including breweries, dairy, and textile industries.
This flexibility is crucial for broad adoption, enabling entities of all sizes to contribute to sustainability efforts and reduce their carbon footprint.
What are the Advantages of Using Biogas as an Energy Source?
Biogas, derived from wastewater treatment processes, offers several advantages as an energy source. It is renewable, reducing dependence on non-renewable energy sources and helping mitigate climate change.
Biogas production from wastewater treatment also contributes to waste reduction and the promotion of a circular economy. Furthermore, using biogas can lead to significant cost savings for industries and municipalities by providing a self-sustained energy supply, improving energy security, and reducing operational costs associated with waste disposal.
For which purposes can recovered energy be used?
Recovered energy from wastewater can be used for various purposes, enhancing the sustainability and efficiency of operations across sectors. It can power the operations of wastewater treatment plants, reducing their energy costs and reliance on the grid.
Additionally, the energy can be utilized for heating and cooling purposes within industrial processes or in nearby buildings, contributing to the reduction of overall energy consumption.
Recovered energy can also be converted into electricity or upgraded to biomethane, a renewable natural gas, offering a versatile energy source for industries, municipalities, and residential areas.
