Co-Composting of Solid Waste Organic Urban with Sludge
Gloria Lucia Camargo Millán 한국외국어대학교 국제지역연구센터 2017 국제지역연구 Vol.21 No.2
Sludge from wastewater treatment plants (WWTP) in municipalities of Boyacá has low levels of heavy metals as required by Colombian regulations, which allows a great potential for use as soil improvers. These, when used in the production of ornamental crops or in the recovery of soils, give rise to a positive environmental impact. This project developed a field trial of co-composting municipal solid organic waste with WWTP sludge in a municipality of Boyacá, finding the optimum proportion of these materials, characterizing the two raw materials and the most suitable mixture. Currently, the requirements for registering the biofertilizer or soil improver are being reviewed before national entities (Super intendency of industry and trade, and Colombian Institute of Agriculture (ICA) with a view to its future commercialization.
