Increasing costs for raw materials and energy and demand for sustainable climate protective waste treatment and recycling techniques have placed technologies like bio-methanation and material recovery facilities (MRF) in the spotlight. The biennial Waste-to-Resources Symposium (24-26 May 2011, Hanover, Germany) combines a conference, commercial exhibition and site visits to address this growing energy and waste management sector. The 2009 edition included participants from 41 countries. Abstracts for 2011’s presentations will be accepted through 4 December 2010. The event will feature simultaneous translation (English-French-Spanish-German) and is being held under the patronage of Dr. Norbert Roettgen, Germany’s Minister of the Environment.
