Maserati Energia biomethane-to-grid plant begins operations

In Italy, Maserati Energia Srl a new constructed biomethane-to-grid plant jointly owned by Maserati Srl and Sebigas Srl has begun commercial operations. Located close to Piacenza, the new plant is designed to treat 50 000 tonnes per annum of organic fraction of municipal solid waste (OFMSW) and 5 000 tonnes annually of green waste to produce up to 5.1 million Nm3 biomethane for the gas grid.

Maserati Energia, a new constructed biomethane-to-grid plant built by Sebigas and jointly owned by Maserati and Sebigas has begun commercial operations. Located close to Piacenza, the new plant is designed to treat 50 000 tonnes per annum of organic fraction of municipal solid waste (OFMSW) and 5 000 tonnes annually of green waste to produce up to 5.1 million Nm3 biomethane for injection into the Italian gas grid (photo courtesy Sebigas).

According to a statement, the plant began receiving feedstock at the end of April 2019. Located on a 35 000 sq.m site, it has been designed and constructed by Sebigas Srl, a subsidiary of Italy-headed Maccaferri Industrial Group that is specialized in the design, construction, and management of biogas plants around the world in the 100 kW to 3 MW scale.

The heart of the plant, where the wet anaerobic digestion (AD) process takes place, is composed of five tanks – one pre-treatment tank, three digesters, and one final post-digestion tank. The raw biogas produced from the AD process is then treated in the specific upgrading system that separates the carbon dioxide (CO2) from the methane, to produce up to 5.1 million Nm3 of biomethane every year to use for transportation.

The different treatment phases optimize the entire process and thus reduce the final waste output. In fact, only 7 percent of the received waste at Maserati Energia – plastics, metals, and other non-organic materials – are not treated. In addition, the plant will produce around 10 000 tonnes of digestate annually that will be composted and used as fertiliser in agriculture. Around 36 000 m3 clean liquid effluent will be discharged

We are extremely proud of this project that not only demonstrates our deep knowledge of the market and its dynamics but most of all confirm our full trust in the use of OFMSW as a resource for the production of electrical energy and methane. Sebigas can guarantee to its clients, the same efficient project development, but most of all the deep know-how acquired from the cooperation with Maserati, from the initial phases of project financing to the operation assistance, maintenance, biological service and after sales, said Marco Bonvini, General Manager, Sebigas.

Novel Italian partnership

Founded in 2017, Maserati Energia represents a first-of-its-kind 100 percent Italian partnership between Maserati – a historic company specialized in composting since 1980 – and Sebigas – a leader in the supply of biogas and biomethane plants – specialized in the complete management of OFMSW: from disposal to valorization for the production of renewable energy.

The Maserati Energia plant transforms the organic waste produced by about 600 000 citizens in one year. Moreover, the plant allows local management of the collected waste, minimizing transports and thus reducing the environmental impact of the entire process, generating high-value economics and incentivizing circular economy and renewables.

The Maserati Energia plant is a very important step towards the future for us. The company is now enriched with cutting edge technology, among the first in Italy, that completes and enhances the transformation process of OFMSW, in which the company has trusted since the beginning. Moreover, this also valorizes the technical know-how that Maserati has gained in the years, remarked Paolo Maserati, CEO, Maserati.
