Waste
As
European society has grown wealthier it has created more and
more rubbish. Each year in the European Union alone we throw
away 1.3 billion tonnes of waste - some 40 million tonnes
of it hazardous. This amounts to about 3.5 tonnes of
solid waste for every man, woman and child, according to European
Environment Agency statistics. Add to this total a further
700 million tonnes of agricultural waste, and it is clear
that treating and disposing of all this material - without
harming the environment - becomes a major headache.
Between 1990 and 1995, the amount of
waste generated in Europe increased by 10%, according to the
Organisation for Economic Cooperation and Development (OECD).
Most of what we throw away is either burnt in incinerators,
or dumped into landfill sites (67%). But both these methods
create environmental damage. Landfilling not only takes up
more and more valuable land space, it also causes air, water
and soil pollution, discharging carbon dioxide (CO2)
and methane (CH4) into the atmosphere and chemicals
and pesticides into the earth and groundwater. This, in turn,
is harmful to human health, as well as to plants and animals.
By 2020, the OECD estimates, we could be generating 45% more
waste than we did in 1995. Obviously we must reverse this
trend if we are to avoid being submerged in rubbish. But the
picture is not all gloomy. The EU's Sixth Environment Action
Programme identifies waste prevention and management as one
of four top priorities. Its primary objective is to decouple
waste generation from economic activity, so that EU growth
will no longer lead to more and more rubbish, and there are
signs that this is beginning to happen. In Germany and the
Netherlands, for example, municipal waste generation fell
during the 1990s.
The EU is aiming for a significant cut in the amount of rubbish
generated, through new waste prevention initiatives, better
use of resources, and encouraging a shift to more sustainable
consumption patterns.
The European Union's approach to waste management is based
on three principles:
-
Waste prevention: This is a key factor in
any waste management strategy. If we can reduce the amount
of waste generated in the first place and reduce its hazardousness
by reducing the presence of dangerous substances in products,
then disposing of it will automatically become simpler.
Waste prevention is closely linked with improving manufacturing
methods and influencing consumers to demand greener products
and less packaging.
-
Recycling and reuse: If
waste cannot be prevented, as many of the materials as
possible should be recovered, preferably by recycling.
The European Commission has defined several specific 'waste
streams' for priority attention, the aim being to reduce
their overall environmental impact. This includes packaging
waste, end-of-life vehicles, batteries, electrical and
electronic waste. EU directives now require Member States
to introduce legislation on waste collection, reuse, recycling
and disposal of these waste streams. Several EU countries
are already managing to recycle over 50% of packaging
waste.
-
Improving final disposal and
monitoring: Where possible, waste that cannot be recycled
or reused should be safely incinerated, with landfill
only used as a last resort. Both these methods need close
monitoring because of their potential for causing severe
environmental damage. The EU has recently approved a directive
setting strict guidelines for landfill management. It
bans certain types of waste, such as used tyres, and sets
targets for reducing quantities of biodegradable rubbish.
Another recent directive lays down tough limits on emission
levels from incinerators. The Union also wants to reduce
emissions of dioxins and acid gases such as nitrogen oxides
(NOx), sulphur dioxides (SO2), and
hydrogen chlorides (HCL), which can be harmful to human
health.
