Cement producer Norcem is basing its energy production on a mixture of industrial and household waste specially prepared and made outside Norway. The household waste is separated at the houses where it is picked up. Included in the process is several stages of metal extraction. This reduces the use of fossil fuels and reduces waste deposits.
An even bigger source of energy is animal dung from cows, pigs etc. The potential is many tens of TWh/year in little Norway alone.
And the unmentionable: human defecation has a huge energy potential, as well as fertilizer potential and huge saving in the use of water.
