Biomass: Generating Energy from Olive Pits
Posted on April, 15th 2014.
Coffee grounds, olive pits, grape stalks, rice and barley husks, pulp – all of these by-products can be burned to generate heat, electricity, biogas and biofuel.Did you know that Micanthus – l also known as “elephant grass” – has a higher energy yield than the same volume of coal? Or that olive pits have a greater heating capacity than diesel? During combustion, a hectare of grain releases as much energy as 4,500 liters of heating oil. Some organic matter reveals incredible energy potential when burned.
Using special recovery processes, this biomass can be transformed to produce heat, electricity, biogas and biofuel. It is now the world’s leading source of renewable energy.
Although most biomass comes from wood and wood by-products, many other surprising – or downright unusual – waste products, including grape stalks, rice and barley husks, pulp and sludge, are also used. Sara Lee’s coffee production plant in Joure, in the Netherlands, dries and burns coffee grounds to produce heat for use in its production process. At its site in Tangier, Morocco, Renault uses boiler rooms fuelled by olive pits to supply its brand new carbon-free plant with hot water.
