Project TypesBiogasBiogas is generated when bacteria degrade biological material in the absence of oxygen in a process known as anaerobic digestion. Biogas typically is a combination of methane and trace elements of nitrous oxide. Through high-tech digester technology this biogas can be ‘scrubbed’ and used as a replacement for fossil fuels such as diesel, bunker fuel and kerosene. This application is most commonly utilised in animal husbandries and to lower COD levels in industrial plants with high-strength industrial wastewater effluent. BiomassWhen products such as food, yard clippings, wood and other organic matter decompose, the gases they give off are collected and burned to create steam which can then be used to generate renewable electricity. This is called Biomass energy. These gases can also be converted into other fuels like ethanol or biodiesel for later use. Unlike wind and solar resources, biomass can be stored and used as needed. Renewable EnergyRenewable energy is energy generated from resources that are not fossil fuel based. Examples are wind, sunlight, sea-tides and geothermal heat. While most of the global renewable energy comes from large hydro plants, technologies such as solar and wind power are fast becoming more financially viable as large sources of renewable energy. Energy EfficiencyEnergy Efficiency is where technology uses less energy to provide the same level of energy output. In commercial or industrial applications efficient HVAC systems and CFL lighting are the main applications to lower emission output.
