In the period Nov 2010 - March 2011 MetaSus conducted a market survey for sustainable waste management and (residual) biomass in Central America and Colombia. Partially as a result of new legislation in waste management and waste water treatment in Costa Rica and Colombia, promising opportunities were identified which were followed up with a proposal for a business mission to the area in the second half of 2011. Special emphasis was put on the identification of clusters of Dutch companies and institutions with an interest in doing business in Central America and/or Colombia. Especially in the field of biomass the interest turned out to be strong. The survey was carried out for the Netherlands Enterprise Agency, with active support by the Chamber of Industries in Costa Rica.
