    Biomass is anything that has a biological origin. Common biomass sources are plants such as wood, corn and maize. If something has an organic origin, it has energy embodied in it that has the potential to be extracted and be used as an energy source.

    Points of interest

    Effluent is wastewater and sewage from towns, cities or businesses (such as what you find left over in the cow shed!).
