How can rural residents in Colombia efficiently and inexpensively dry firewood for clean cookstoves?

This initiative is part of the Conservation Landscapes Program, funded by USAID, and developed by The Natural Heritage Fund (Fondo de Patrimonio Natural), in alliance with Minka-Dev. These organizations promoted a co-creation process, in collaboration with rural communities in the Caribbean Region of Colombia, to design clean cookstoves and develop a sustainable business model to create access to them. Given the humid and cold climate in parts of Colombia, a need exists to improve the ability to dry wood inexpensively. This challenge focuses on the generation of alternatives to dry firewood in regions above 3000 meters, with low sunlight and no electricity.

This contest digs deeply into a local issue with global implications: it seeks inexpensive technologies, practices and resource management strategies that will improve the quality of wood in humid and cold rural areas in developing countries. There’s a lot more to the story, so be sure to

Keeping It Small and SimpleiWENN

Build simplistic wood splitters/cutters using old car parts to allow for safe wood reduction to cook stove size. Small wood dries faster!

Roasting firewoodbaggettm68

By roasting the firewood for the next cooking fire on the stove after cooking a meal less wood should be required and less GHG produced.


Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy.

Briquetting is the best option.davidafricangreenmovement

Bio briquettes produces clean and efficient energy it saves the forest and is mitigation and adaptation strategy against climate change

Solar Klinnaresh

Wood drying reduces the moisture content of wood before its use.

Solar Wood Dryernaresh

Solar powered wood drying reduce the moisture content of wood in half the normal time.

Passive Solar Firewood Dryerhira

Passive solar firewood dryer uses free heating direct from the sun.

The Solution of Surplus.Woodlands 2000 Trust

A surplus of hardwood timber trees could create a dry firewood off cuts supply.
