fifty tons a day of OFMSW.

500 to 800 kW. CO2-negative electric power.

50 to 70t tons of clean and pure organics, the organic fraction of municipal solid waste OFMSW are easy to collect as these waste streams are available in aggregated form with the big producers. All it takes is to slightly re-organize the collection process, pick up the clean and pure waste and don’t mix it with ordinary household waste.

Can we manage this? Can we reorganize the daily collection process at a hand full of the largest waste producers in such a way that waste remains usable/clean and pure to avoid massive problems downstream and produce a lot of clean energy? We won’t collect any more or less waste. Total volumes and weight will remain the same. So, YES, we can!

What waste? Where do we find the pure and clean OFMSW in aggregated form? What are the inputs?

  • Restaurant and hotel kitchens’ waste,
  • Canteens waste of hospitals, universities and the military,
  • Slaughterhouses waste from red meat and poultry production, blood, intestines, grease, gut content, sludge and wash waters without detergents,
  • Markets and wholesale markets waste of fruits and vegetables,
  • Supermarkets, expired and degraded food stuff waste, food returns,
  • Confiscated food that needs to be destroyed,
  • Agro-industrial waste of food processing facilities, canneries, juice production, dairies, etc.

What are the outputs?

  • Clean, CO2 negative 500 to 800 kW of electric power. 24/7 all year round, more than 8000 hours.
  • 4 to 5.7 million kWh el., net (after own parasitic consumption).
  • 2.7 to 4 million thermal kWh in the form of 90°C hot water, to replace fossil fuels, that too is net (after own parasitic thermal consumption).
  • 25,000 to 30,000 tons/year of digestate, a high quality natural bio-fertilizer, rich in mineralized nutriments, to be spread on agricultural fields or the city’s gardens and woods.

What are the other benefits?

  • Savings in leachate treatment costs for leachate that isn’t being produced in landfills and hence must not be treated: 9,000 to 13,000m3/year at the going rate of costs of 200 MAD/m3 of leachate treated, this represents savings of 1,800,000 to 2,550,000 MAD/year.
  • Savings in transport costs, as the waste treatment plant can be placed within the perimeter of the city, there is no need to transport to far places.
  • Savings in greenhouse gas emissions (methane) of 20,000 to 30,000 tons of CO2 equivalent/year, to be valorized through carbon offset or trading schemes (negativity of CO2 emissions).
  • No costs for the terrain of the landfill, the landfill will last longer, as the OFMSW does not enter.
  • Employment of 20+.
  • Creation of a first of its kind in Africa, a 100% sustainable waste treatment solution.
  • Without noise, odors, enclosed.
  • With only positive sanitary or environmental impacts.

Benefits are economic, social and environmental, to be shared between city, society and the operating companies.
