Small biogas plants in Nepal
Since 2019, wpd has been supporting a joint project in Nepal with the German non-profit organisation atmosfair. Through this project, wpd is funding the construction and repair of small-scale biogas plants in Nepal. These replace open fires, thereby reducing the demand for firewood and the associated greenhouse gas emissions. Furthermore, open fires can cause serious eye and lung diseases. The biogas plants are fuelled by otherwise unused cow dung, which is converted into biogas through anaerobic digestion. The biogas is piped to gas cookers in the kitchens. According to the project organiser, such a biogas plant can save approximately 2,000 kg of firewood each year – and thus two to three tonnes of CO2 – compared with the use of an open ‘three-stone fire’. After fermentation, the remains of the cow dung can be used as fertiliser, contributing to the agricultural use of the land.
As part of this existing project partnership, we have been supporting a local waste management project in the Langtang region of Nepal since September 2022, in addition to the construction of further biogas plants. In this remote region, there is no formal recycling system; instead, there are informal waste dealers for certain raw materials. Waste is dumped in open areas and, in some cases, burnt in the open air. The aim of the project is to raise awareness and offer practical solutions, namely to establish a central waste collection point and ensure the removal and recycling of the waste.

More Information
The project contributes to equitable access to affordable clean drinking water.
wpd has ensured the electrification of a health center by installing a rooftop solar system.
wpd supports the rewetting of a small area of marshland in Mecklenburg-Western Pomerania in collaboration with the State Forestry Institute of Mecklenburg Western Pomerania.
Within the company, many steps have already been taken with respect to sustainability.
The project has also set itself the goal of protecting existing forested areas and reforesting areas that had been cleared, preserving the natural biodiversity, as well as serving as a centre for information and training (both theoretical and practical) in the sustainable use of forests.
Traditional lighting sources such as petroleum lamps, candles or small, battery-driven lamps are being replaced by the distribution of solar lamps.
