General Contractor and Technology Integrator in Biogas and Biomethane

Cost-effective one-stop shop — from plant design to gas distribution

A biogas plant consists of many different components, and our priority is always to identify the technologies, that best meet the customer’s needs and to make them work seamlessly together. There is no one technology that suits all, and every case is different. We deliver plants on a turnkey basis, from engineering to commissioning and operation.

We work as general contractor in designing and managing biogas plant projects with specific feed stock and goals of profitability and sustainability. As an EPC Contractor we take care of engineering, procurement and construction of biogas plants. We also take care of the maintenance of the plant and helping in operation, as well as modernization the plants already in operation. Besides our home country Finland, we operate also in other Northern Europe countries such as Norway, Baltics and Poland.

Own technology for biomethane and biogas

We can also help you to upgrade your biogas plant. Biovoima has several own technology for biomethane and biogas production. Nevertheless, we are a technology- neutral operator, which means that we will always find the best equipment for your needs. Our experts will find the optimal solution from the profitability and sustainability point of view.

Biogas plants – a way to turn organic waste and side streams into revenue

Biogas plants have the ability to turn the organic waste and side streams into revenue by cost-effectively converting them into renewable energy and biofertilizers. The products can be used to generate electricity or heat or processed further to make biomethane, which can be used as a transportation fuel or as a substitute for fossil gas in natural gas networks. The opportunities for scaling are practically endless.

Profitability of a biogas plant

An investment in a biogas plant can pay itself back in a couple of years. There are, however, many factors at play, including the following:

Reception of the material to be fed, i.e. gate fees
Savings in processing costs
Gas-generating properties of the feedstocks
Applications for the end product and the revenue they generate
Revenue streams and/or savings from the use of the end product as a fertilizer
Choice of technology and energy efficiency of the plant
