During a volunteer mission in Bolivia, Arthur Laurent saw with his own eyes the impacts of traditional cooking methods on families living in the Andes. The strong indoor pollution caused by the lack of clean technologies and the aggravation of deforestation were one of the reasons why Arthur wrote his thesis on the subject and created Microsol, a social business that has the ambition of helping the poorest people in Latin America - who often are the most vulnerable to climate change - by providing them with clean cooking technologies.

The rural areas of Sichuan province are among the least developed in China. The average annual per capita income of poor farming households in Sichuan is about 500 euros, and the province has 43 counties that have been officially defined as national poverty counties in order to qualify for government economic assistance. Sichuan is also very vulnerable to natural disasters. In 2008, a massive earthquake killed nearly 70,000 people and left 4.8 million homeless. In addition, an estimated 12 million livestock were killed in the devastating event. At the time, the German project developer UPM Umwelt-Projekt-Management GmbH and its Chinese cooperation partner Chengdu Oasis Science & Technology, Co. Ltd. decided to help as many smallholder farming households in Sichuan as possible to overcome poverty while contributing to climate change mitigation. Two years later, they started to develop their biogas development programme for poor rural households in Sichuan under the CDM. This programme of activities (PDA) aims to equip up to one million low-income rural households in China's Sichuan province with advanced biogas digesters and smokeless biogas stoves. These units are installed and maintained by the Sichuan Rural Energy Office (SREO) and its many local biogas technicians. The small, robust and reliable biogas digesters avoid methane emissions from pig manure and carbon dioxide emissions from coal and firewood. They provide participating farm families with clean, renewable and free biogas that they can conveniently use for cooking, heating or lighting.

Agricultural practices have been shaping the landscape and way of life in the Dutch provinces of North Brabant and Limburg for several centuries. Even today, these regions remain predominantly rural with limited heavy industry, and the agro-swine industry continues to hold considerable importance. In fact, these provinces are home to the majority of swine farms in the Netherlands. This high concentration of livestock has already resulted in a situation where the soil's nitrogen absorption limit has been reached, preventing the complete disposal of manure on local fields. In the winter time, livestock manure is stored in tanks for a period of six months or longer before beeing utilized as fertilizer for farmlands. The manure when kept in pits, tanks or lagoons undergo anaerobic fermentation and release greenhouse gases (CH4, CO2 and N2O) to the atmosphere. The project created an anaerobic digestion setup with a grid connected Combined Heat and Power plant (CHP) attached, using primarily pig and cattle manure for fermentation, as well as co-ferments such as liquid and solid food wastes from agricultural and industrial food production processes. The electricity produced is fed into the national electricity grid. The thermal energy generated is used for heating the project's own processes (digesters), but also for heating the nearby pig and poultry stalls, for producing organic pellets fertilizer or for the hygienization of digestate.
