A biomass team in the Berlin district of Pankow is developing plans to heat two greenhouses with biogas plants fired by local green waste. Although planning permission has not yet been granted, the demonstration project has received lottery funding due to its potential contribution to Local Agenda 21 in the city.
The British Embassy’s environment team in Berlin report that the project to install a biogas plant in Pankow’s botanical gardens would be the first case of a biogas plant replacing an existing oil heating system in Berlin. The project would cut the existing EUR110 000 annual heating cost for the two greenhouses by 90 per cent. The plans would be viable if biomass were collected within a 15 km radius of the greenhouses. This would include waste such as tree and hedge clippings, grass cuttings, weeds, market and restaurant waste and domestic organic waste.
The project has been developed by the Biomass Roundtable, which comprises 40 environmentalists, gardeners, scientists, Berlin civil servants and local businesses. The Roundtable has attracted ?10 000 in lottery funding from the Berlin IZT, which funds sustainable projects. The aim of the project is to prove that biomass use should not be restricted to the countryside. In the future, the Roundtable suggest that a large part of Pankow’s energy needs could be met by locally-sourced biomass.
According to figures from mid 2002, Germany has 200,000 biomass plants powered by agricultural waste. The Environment Ministry predicts that growth in biomass output will be on a par with developments in the wind industry.

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
