Energy usage of spruce with waste face masks and spent coffee grounds as fuel in a pellet boiler.

It is necessary to reduce dependency on fossil fuels for heating and waste generation, while also utilizing the energy potential of waste materials. One possibility is to create fuel pellets where waste makes up a small proportion so that the properties of the wood are not significantly altered with.
