Waste Treatment Plants: Composting and Waste to Energy Plants


Composting Plant


  • Mature compost within 7 weeks time (Certificated) - Fermentation and Maturation included. Linear bagging automatic system

  • No civil work needed in any form compared to other standard and expensive systems such as windrow or tunnel composting that need costly investments

  • windrow turner needed because our system generates homogenous and porous material initially and because of the microclimate originated in the interior of the bags which accelerates the aerobic fermentation


Waste to Energy Plants


  • High NCV (Net Calorific Value) and low humidity SFR (Solid Fuel Recovered) through linear bagging system


In general


  • No civil work needed in any form

  • No covered building needed

  • Wide production range: 1.000 – 200.000 TN/year

  • Energy- saving forced ventilation system

  • No presence of leachate nor odor, which means no biofiltre system needed

  • Space optimization: our system optimizes the working surface more than any other existing system

  • Self stockage system in linear bags, no stockage building needed

  • Automatic remote control without any on-board man needed

  • Low operation costs and low investment, which means a rapid return of investment in all terms




Ritorna Medio Ambiente is specially focused on Composting Plants as well as on Waste to Energy Plants, especially interesting for Cement Manufacturers in order to produce low cost combustible.

Application Industries


  • Sludge composting and drying, organic fraction composting from MSW (Municipal Solid Waste), pruning and green waste composting, organic waste composting, animal manure composting of any kind, food waste composting, composting of AWM (Animal Waste Management), in vessel composting, etc

  • SRF (Solid Recovered Fuel) Installations - Waste to Energy Installations to produce secondary fuels, especially interesting for those energy intensive industries that need to produce heat in their process (incineration- coincineration, cement industy , etc) in order to save on primary fuels
