THE USE OF WASTE FOR
ENERGY PRODUCTION
• there are two theories about fossil fuels: a) fossil fuels are abundant and will never
disappearb) oil supplies wil disapper in 34 years,natural gas in 55 years and coal for 127 years
• We have to replace fossil fuels with renewable energy sources
• We can get fuel, biogas and methane from waste
• oil• coal• natural gas
Non-renewable energy sources
• wind, water, solar energy
Renewable energy sources
Windmills and solar panels =energy from wind and sun
Renewable energy sources
• Nuclear plants do not emit carbon dioxide, which is harmful to the environment, but nuclear fuel becomes radioactive and must be stored for decades in the security concrete pools.
• If the storage error occurs, an accident of gigantic proportions like those at Chernobyl in 1986. and Fucushima 2011. could happen.
Nuclear power plants
• Biomass is what most people consider garbage like trash, garden waste, wood chips and even manure.
• The biomass is fed into a large funnel and then into the oven where mass burns. As the waste decomposes, it produces methane, which is collected in tubes. Methane can be burned in a power plant to produce electricity.
Methane
• Fuel produced from paper, wood, textiles and small plastics under controlled conditions.
Fuel from waste
• Most of you don’t know Sweden is importing waste from other European countries. Importing garbage is not a common thing, is it?
• Swedish have a reason for it, given the modest production waste, they imported it because they have an incinerator and operations would close without imports.
