CH4pa - A biomethane fuelled modular transportation and working vehicle for farmers, cities and transport companies in emerging markets

The CH4pa ("chapa" means buddy in Portuguese) is a working and transport vehicle for small and medium farmers in developing countries. It combines the features of a tractor and a pickup truck and saves 50% of the fuel costs because it is fuelled with biogas from the farmer´s own residues.

CH4pa is a practical innovation, developed to meet the needs of the Brazilian farmers. and a prototype was built and tested in the province of Paraná in the south of Brazil. The main USPs of CH4pa are: -Low costs with biomethane as a fuel -Modularity and flexibility due to different transportation bodies and 3-point hutch for standard tools -Easy maintenance because a very robust design and standard parts -Energy self-sufficient and environmentally friendly CH4pa is produced by local tractor manufacturers in a licence agreement. The chassis, which is produced from steel plates that are cut, bend and welded does not need high investment costs in machinery.
