MARMOLEJO R, Luis F et al. Local quantification and characterisation represents a basic tool for integrated residential solid waste management. Ing. Investig. [online]. 2010, vol.30, n.2, pp.96-104. ISSN 0120-5609.

A sampling and characterisation plan for residential solid waste (SW) produced in the city of Cali in Colombia was developed between January and September 2006; this required designing an undisclosed strategy in the country and the results showed the need for an adjustment to the current SW Colombian classification scheme. The available sampling frame made a two-stage sampling plan necessary, block side (BS) being the first stage and household BS the second. A 0.39 kg/(person-day) solid waste per-capita production (PCP) was found, which increased with socioeconomic status. Food waste was produced most, a large part consisting of cooked food. Waste from personal hygiene items was a third category, although this is not currently a category which is included in Colombian Technical Standard -RAS 2000. Although characterisation techniques are used worldwide, the results showed the relevance of available sampling framebased local characterisation, using local data for sampling methods and associated sample size selection.

Keywords : solid waste classification; block side; sampling framework; sampling plan; per-capita production (PCP).
