Europe: Nestlé Waters opens Swiss biogas plant


After works lasting more than one year, Nestlé Waters and Groupe E Greenwatt have inaugurated Switzerland’s largest agricultural biogas plant in Treize-Cantons, next to the Henniez bottling plant.

“The development of local and renewable energy meets the objectives of the canton’s energy policy,” said state councilor Jacqueline de Quattro, head of the regional development and environment department.

“It opens up the way for the energy transition and improves our security of supply.”

“This plant has all the ingredients of a pilot project that will surely inspire other initiatives,” said Nestlé Waters CEO Marco Settembri.

Financed, built and operated by Groupe E Greenwatt, the plant will use 25,000 tons of agricultural fertilizer from 27 farms in the region every year.

About 3,800 tons of organic waste from the processes that produce Nespresso and Nescafé will also be used as a raw material to produce biogas.

The plant will produce 4 million kWh of electricity and 4.5 million kWh of heat by burning this gas in a cogeneration engine.

The heat will be consumed in the Nestlé Waters bottling plant, whose proportion of renewable energy will exceed 50%.

By replacing energy generated using fossil resources, the biogas plant avoids the emission of 1,750 tons of CO2 into the atmosphere every year.

The residual material left over at the end of the process constitutes a high-quality fertilizer that is used by partner farms.

Since the methane is extracted in the process to produce the gas, these digested effluents make hardly any smell when they are spread.

They have a very high nutritive value, are better assimilated by plants that mineral fertilizers and meet the criteria of all the most common organic labels.

The Treize-Cantons biogas plant marks a new chapter in the ECO-Broye program launched by Nestlé Waters in 2009.

Its aim is to stimulate and coordinate efforts to preserve the natural resources of Henniez and its region by involving farmers, authorities and key stakeholders in joint projects.

In the environmental field, the company is aiming to cut the CO2 emissions from its production facilities in Switzerland by 50% between 2010 and 2020.

It also intends to reduce water consumption in its production sites in Switzerland by 50% by the same deadline and aims to consume only 100% responsible supplies by 2020.
