In developing countries, residual biomass usage by means of anaerobic digestion offers
several benefits and opportunities, such as a sustainable energy source, production of organic
fertilizers and new agrobusiness models. In Latin America, Colombia is one of the most
promising markets for the implementation of this technology in terms of availability of biomass
and economic growth, as recently reported by local government organizations. In this paper,
special attention is given to Antioquia, a department of Colombia with the largest farms of cattle
and pigs, according to information reported in 2018 by the Ministry of Agriculture and Rural
Development. It is estimated that manure from the porcine subsector in Antioquia has an
approximate technical-energy potential of 1,896 TJ year-1
, varying from 1,611 to 2,186 TJ year-1
,
corresponding to the 95% confidence interval. In the case of manure generated by the livestock
subsector in Antioquia, it is estimated a theoretical energy potential of 8,566 TJ year-1
. However,
traditional extensive production systems disseminate manure through the pastures turning
centralization of the available residual biomass a difficult task and not senseful. Based on the
local practices of the specialized dairy subsector, it is estimated that manure collected during the
milking process could reached up to 25% of the total available. Biochemical conversion of this
amount of biomass has an estimated technical-energy potential of 187 TJ year-1
, varying from
156 and 236 TJ year-1
, corresponding to the 95% confidence. The aim of this article is to estimate
the technical-energy potential for the livestock and porcine subsectors in the Department of
Antioquia, based on the available residual biomass according to local farming practices.
