Abstract / Excerpt:

In countries where a centralized municipal wastewater (WW) treatment is too expensive to operate, the concept of resource-oriented waste management is meant to address global sanitation problems as well as the problems recognized from centralized WW management (Wilderer 2001, 39-54). This concept focuses in the separation of WW flows and organic waste at the source, that is household level, and then treating each WW stream accordingly in decentralized systems for subsequent reuse of water and nutrients, and recovery of energy.

Anaerobic digestion (AD) is a sustainable process which has gained popularity in today's efforts toward sustainable development development and renewable bioenergy production. AD is a biochemical technology that is capable of converting a wide range of organic materials into biogas, which contains methane (CH4), a main component of natural gas (Deublein and Steinhauser, 2011), and carbon dioxide (CO2). It is one of the sustainable approaches that combines waste treatment and recovery of useful by-products, and is even considered as the core technology for the recovery of energy and nutrient from source separated domestic WW (Otterpohl 2002, 149-158; Kujawa-Roeleveld and Zeeman 2006, 115-139).
