Thermal XPS insulation

The biomethane facility is rising on recycled insulation from BEWI

In the village of Tahula in Saaremaa, Estonia, a biomethane plant is currently under construction, resting on insulation boards from BEWI. Once completed, the facility will produce biomethane from agricultural waste. With an annual production capacity of 58 GWh, the plant is expected to cover 15 per cent of Saaremaa municipality’s electricity needs and 25 per cent of its heat energy consumption. The site includes several production halls and silos, as well as an office building.

Solid foundation of recycled materials

5 550 square meters of Terra XPS (extruded polystyrene) insulation boards form a solid and durable foundation for the plant. The material offers excellent thermal insulation and moisture resistance, contributing to high energy efficiency.

“We supply Terra XPS perimeter insulation for the ground areas. Terra XPS is made with 45 per cent recycled material, offering a 30 per cent lower CO₂ footprint compared to conventional XPS,” says Artur Mackevic, Key Account Manager in BEWI Lithuania.

15 tonnes less CO2

By combining functionality with environmental benefits, Terra XPS supports the project’s climate ambitions. The use of Terra XPS instead of conventional XPS reduces the project’s carbon footprint by 15 tonnes of CO₂.

“By choosing Terra XPS, the contractor contributes to environmental progress and is brought closer to its climate reduction targets. This is a clear example of how recycled products, developed through our circular approach, can make a real difference,” Mackevic ends.

Becoming circular

Terra XPS is part of BEWI’s broader efforts to enhance circularity. The company collects and recycles used EPS (expanded polystyrene) packaging and insulation, such as fish boxes and construction debris. Last year, BEWI collected 33 000 tonnes of used EPS for recycling, more than any other insulation company. This has enabled a 77 per cent increase in the use of recycled raw materials, and the development of new circular products, like Terra XPS.
