Development of Briquettes from Waste Wood (Sawdust) for Use in Low-income Households in Piura, Peru

The paper presents the results of a project focused on the development of briquettes from the waste wood (sawdust) resulting from the main waste from timber companies located in the Piura Region of Peru. This waste wood currently lacks a useful purpose, and its indiscriminate burning generates CO and CO2 emissions. Through a drying and compression process, sawdust briquettes were obtained with the following features: 19.8 MJ x kg, 10% of humidity, 894 kg/m3, 1.3% of ashes, 15,29% of fixed carbon, and 83.41% of volatile matter. The results achieved show that sawdust briquettes are a perfect substitute for the fuels coming from illegal logging of the dry forest reserve in Piura that are currently used in domestic stoves (e.g. charcoal, firewood) by 55.81% of families in the region. In order to investigate the acceptance of the substitute product, eleven communication and awareness workshops were conducted reaching over 600 families, in addition to product testing for 127 families in five low-income areas of the Piura region.
