English Abstract This report presents the results of the second series
of sorting analyses with household waste, collected after separate
collection at source in the municipality of Lemsterland. The sorting
analyses took place in october 1991 and form part of a pilot project, called
'de dubbele duobak' (dual duobin). The main purpose of this project is to
achieve a more extended reduction of the amount of household waste by
separate collection at source. In Lemsterland each household is provided
with two dual-chamber wheeled bins. The first bin contains a paper/carboard
fraction and a mixture ('PMD') of plastics/metals/drinks-packaging
(laminated cardboard); the other bin contains a fraction of garden, fruit
and vegatable waste ('GFV') and a residual fraction. Of each fraction two
samples were collected at two different locations and analysed on the
composition, purity and response. The results on GFV- and paperfractions
showd a purity which amount to 96% or more, and a response of more than 80%.
The PMD-fraction showed a purity of 70% and a response of 67%. The response
of glass containers (glass does not form part of the house-to-house
collection) showed also a very high response rate (92%). A provisionally
estimate on the total reduction of the amount of household waste, based on
the results of the participating households in 1991, showed a recycling
percentage of 58%.
