AIM Strategic Database for Waste-Example of technologyIn the case of food waste management:• Simple incineration ➔ ash• Incineration with power plant ➔ electricity & ash• Composting ➔ manure• Gassification ➔ methane• Process to feed ➔ animal feed
• Direct final disposal
SDB on waste management technology⇦ Inputs (capacity, energy, labor, capital cost, ...)⇨ Outputs (residual, pollution, recycled goods, ...)
