reduction. However, in evaluating the method, one should take under consideration the potential environmental burdening from the cleaning, the
disinfection and the transportation of reusable objects and also the fact
that reusable packaging is usually sturdier and heavier; thus it requires
greater consumption of energy and other natural resources.

agement method of USW. It diminishes environmental burden and contributes to natural resource saving. Urban solid waste suitable for recycling is
mainly paper, glass, metals, plastics and construction and demolition waste.
The citizen makes sure to dispose of the various materials in different bins.
In parallel, he can also apply a system of domestic or municipal composting
of fermentable waste. An additional important advantage is that sorting at
source turns the greatest part of USW from rubbish to raw materials and
in this way the negative environmental impact from the transportation of
USW by collection vehicles is minimized.
Sorted-out materials are received by corresponding industries that produce recycled paper, metals, glass etc. Recycling with sorting at source is
technologically and financially feasible, although for certain materials, as
for instance glass, its cost effectiveness is marginal and sometimes the need
for subsidy may arise. Cost effectiveness for glass, paper etc. improves if
further sorting into different qualities is carried out.
Recycling is a widely applied and rising technology in most developed
countries, where it is promoted with priority. It is compatible with the
increasing environmental protection requirements as well as the evolving
European environmental policy. A recycling programme with sorting at
source should include special actions for the change of social behaviour and
achievement of social participation, effective organization of collection and
disposal of recyclable materials and provision for management and gradual
decrease of the waste quantity that will be created by imperfect sorting. The
cost and materialization time of such a programme are definitely smaller
in comparison to other costly and ineffective solutions such as mechanical
sorting or sanitary landfills that often cannot achieve social acceptance.
10.3.8 recycling by Manual Sorting
Another form of USW treatment is recycling with partial sorting at source
completed by manual sorting in sorting centres. The citizen takes care to
dispose of all recyclable materials together, e.g. packaging, in special bins
from which they are picked up by special vehicles and taken to the sorting centre. There, the centre’s personnel performs manual sorting of the
reduction. However, in evaluating the method, one should take under consideration the potential environmental burdening from the cleaning, the
disinfection and the transportation of reusable objects and also the fact
that reusable packaging is usually sturdier and heavier; thus it requires
