Biowaste ending up in mixed waste to be used to make road fuel – collaboration for new climate solutions

Finland generates an annual total of more than a million tonnes of mixed waste burnt at waste incineration plants. Mixed waste sent for incineration also contains significant amounts of biodegradable waste that is a valuable feedstock in biogas production. The use of renewable biogas can help achieve significant transport emission cuts. Together with the waste management company Lounais-Suomen Jätehuolto owned by 17 municipalities in Southwestern Finland and the waste-to-energy company Lounavoima, Gasum is looking for a solution on how biowaste included in incinerable waste sent to an upcoming waste-to-energy plant could be utilized in biogas production.

Mixed waste generated in homes typically contains 35-40% biodegradable waste such as food scraps and kitchen paper that is not of significant use at incineration plants in terms of energy production. A larger proportion of waste can be recovered for energy by utilizing biodegradable fractions in biogas production.

Gasum, Lounais-Suomen Jätehuolto and Lounavoima are partnering in a joint project to explore the opportunity to build a waste pre-processing system that will enable the utilization of biodegradable fractions in biogas production to make fuel for transport.  The pre-processing equipment would also enable the removal of other waste fractions such as recyclable metal from waste suitable for incineration.

The separation of biodegradable fractions from mixed waste will not eliminate the need for separate collection of biowaste. Instead, it will supplement existing solutions.

"The best alternative would be no biowaste ending up in mixed waste and all biowaste being delivered via separate collection directly to biogas plants.  However, the separate collection of biowaste does not make that much sense in areas with mainly detached and semi-detached homes or in sparsely populated areas as the volumes per household are low in relation to the collection costs. For as long as there is biodegradable waste ending up in mixed waste, it is important to find solutions on how to utilize it," says Ari Suomilammi, Director, Circular Economy Finland, Gasum.

Increased biogas production plays a major role in action to reach transport emission reduction targets

Reaching the climate targets set requires significant increases in renewable energy production and, consequently, new collaboration models and solutions. Biogas is a local and renewable fuel that can help cut greenhouse gas emissions from transport by up to 85%.

"The Waste-to-Energy plant’s annual volume of 120,000 tonnes of incinerable waste could provide feedstock for the production of more than 40 GWh of biogas – enough to fuel around 4,000 cars for a year,” says Ari Suomilammi.

Gasum has made a strong commitment to transport emission reduction targets by building the Nordic filling station network for heavy-duty road vehicles and offering consumers biogas at Gasum's filling stations in Finland.

A biogas plant is being planned in conjunction with the project, but no construction investment decision has yet been made and the type of collaboration between the partners involved in the project will be specified further later on this year. The feasibility study involves a comparison of the suitability of the Topinoja, Turku, and Korvenmäki, Salo, waste treatment centers for waste pre-processing and biogas production. Gasum will continue the planning of similar projects with other eco-power plants, too.

Gasum's biogas plant in Lohja to increase Finnish biogas production significantly

Gasum’s Lohja biogas plant project is moving ahead as progress is made in design and procurement. To be constructed in conjunction with the Lohja Munkkaa waste management center, the plant will process an annual total of 60,000 tonnes of biowaste. The plant is expected to produce more than 40 GWh of biogas and 50,000 tonnes of organic fertilizers per year. The commissioning of the plant is scheduled for 2020.

The project will enhance the growth of the Finnish biogas market and strongly promote the transport fuel use of biogas. Project construction work is due to begin in April and be completed during 2020. The job-creation impact of the Lohja project will be around 170 full-time equivalents of employment during the con-struction phase, while the permanent employment effect will be around 32 full-time equivalents.

”It’s great that work on our biogas plant project is starting as progress is made in the planning phase. Developing the biogas market and the transport use of biogas as well as increasing the biogas production capacity are essential elements of the Gasum strategy,” says Matti Oksanen, Director, Business Development, Biogas, Gasum.

The investment is significant for Gasum. The Ministry of Economic Affairs and Employment has granted Gasum €7.83million in ’Bioeconomy and clean solutions' key project support for increased biogas production.

Gasum’s current biogas capacity is around 650 GWh per year. At its 12 biogas plants in Finland and Swe-den, the company processes around 800,000 tonnes of biomass per year. Gasum is the leading processer of biodegradable waste and supplier of biogas in the Nordic countries. The company’s biogas plant devel-opment projects are underway in locations such as Turku and Oulu, Finland and Nymölla, Sweden.

Biogas retail sales to Suomen Kaasuenergia

Biogas distribution sales agreements will be transferred to Suomen Kaasuenergia. Gasum Ltd has sold its biogas distribution sales agreements to Suomen Kaasuenergia Oy on June 1, 2018. The arrangement will result in Gasum selling biogas to Suomen Kaasuenergia, which will offer biogas directly to biogas distribution customers. Gasum will still continue to supply biogas to its wholesale customers and gas distribution sellers in Finland.

In addition to the agreement between Gasum and Suomen Kaasuenergia on biogas distribution, the companies will promote the awareness of biogas and the Biogas Label and the sales of biogas. The companies have also set the objective increasing the share of biogas in Suomen Kaasuenergia gas networks.

The Gasum strategy is to expand the gas market and build a bridge towards a carbon-neutral society on land and at sea in the changing operating environment together with its partners.
