Invited Session: Energy Recovery

Anaerobic Digestion of Organic Fraction from Municipal Solid Waste (0.5 CEU)

Room 320

Since 2009, a mechanical-biological treatment (MBT) facility for municipal solid waste in the Reus/Tarragano region in Spain has been processing the organic fraction of the municipal solid waste from around 100 communities with a high solids anaerobic digestion system, producing electricity for around 2,500 households. Previously, all municipal waste had been landfilled or incinerated. As a key component of the MBT facility, three horizontal plug-flow digesters process the organic fraction separated out from municipal solid waste and convert it into biogas and fertilizer. This way organic waste can be used to generate renewable energy, closing the materials cycle sustainably.

By attending this presentation, participants will be able to learn about the beneficial and higher and better use of organics from municipal solid waste.
