If Europe minimised landfilling and maximised the use
of waste as a resource, the future would look great for recycling and
Waste-to-Energy (WtE). At the same time this would be beneficial for
environment, jobs and growth in Europe.
In order to achieve this, the right steps have to be
undertaken by EU policy makers. An important step will be the future ‘Circular
Economy’ package. The European Commission should come up soon with ‘a broader and
more ambitious’ proposal, as announced in the European Parliament on 16th
December 2014 when the Commission Work Programme for 2015 was presented, withdrawing
the current Circular Economy proposal.
In a recent communication entitled "Towards a
circular economy: A zero waste programme for Europe” ,
accompanied by a legislative proposal for the review of the waste
targets, the European Commission further proposes a framework for reaching
a resource efficient economy through addressing waste management activities.
Apart from input to the energy system, WtE plays an important role
in diverting waste from landfills. In doing so it goes hand in hand with
recycling. It also ensures a high quality recycling by treating all
residual waste that is not suitable to be recycled. „Recycling of many
waste materials certainly provides valuable products but also – and
inevitably if the aim is ‘clean cycles’ – it produces
recycling residues that are unsuitable for further use and that
have to be disposed of in sinks. Thus, "landfilling and
incineration are as essential as prevention and recycling, and
they depend upon each other to get the job done” .
New recycled materials depend on the quality of the sorted waste.
It is worth noting that there are some materials which are too dirty or
too contaminated containing, for example, flame retardants or heavy metals
and mixed materials that are too difficult or too expensive to sort.
In addition, materials degrade after repeated recycling
(in particular, plastic and paper fibers lose their properties) and
the sorting activity produces residues that need to be treated. „Recycling
does have limits and is a means to higher level targets – not a goal in
If high quality recycling is not possible, the waste should be
turned into energy, rather than being landfilled. Even countries with the
highest recycling rates in Europe, Germany, Belgium, Sweden, Netherlands,
Austria and Denmark that landfill less than 10% and recycle above 50%
of their municipal waste depend on WtE to treat the remaining waste
that is not suitable for recycling. All these countries have introduced
landfill bans in order to recycle as much as possible and to turn into
energy the waste which is not suitable for recycling.
WtE diverts waste from landfilling, reduces volume and sanitises
waste, provides final sink for pollutants and keeps them out of the
Quality recycling is a vital issue. Rather than just focusing on
quantity, quality should receive greater attention in the on-going revision. For
this we need clear definitions, accurate measurement, better data and
transparency about what goes in and what goes out of sorting and recycling
These mass balances exist for WtE. Information is widely available as
WtE plant operators strictly document what goes into the plant and what goes out,
i.e. energy and residues. From the latter precious metals are recycled.
Indeed, a holistic approach that not only looks at raw material supply, but
also considers affordable and secure energy delivery must be taken. Supplying
citizens and industry with cost-effective and reliable local energy is an
important aspect with regard to Europe’s growth, security of energy supply as
well as energy and climate goals, which are in the focus of the European Energy
Union. This kind of energy is generated by WtE plants from waste that is not
good enough for recycling.
The amount of waste sent to WtE plants is determined
by quality recycling, and the acceptance of recycled materials on the market.
WtE plants take the rejects from sorting and recycling facilities, as normally not
100% of the waste collected for recycling becomes recycled products in the end,
e.g. due to poor quality. They have to be treated in WtE plants to ensure that
pollutants do not enter the circular economy.
If Europe is serious in minimizing landfilling and
maximising the use of waste as a resource, we need investment in treatment
capacity, i.e. sorting, recycling and other recovery options. WtE capacity in
EU28 varies a lot. Some Member States have practically no WtE capacity, but
landfill most of their municipal waste. At the same time there is a great
discussion about so-called overcapacities for WtE in some regions, mostly where
the use of waste for heating purposes or combined heat and power is highly appreciated.
It must be considered that the Member States which have some spare WtE
capacity are also the ones to achieve high recycling rates. They have progressive
source separation systems and work to ensure that only waste that has gone
through these systems enters WtE plants.
It is worth mentioning that sometimes WtE "overcapacity” might be
overestimated as often only the amount of municipal waste generated in the
region is taken into account. However, apart from municipal waste, WtE plants
also treat considerable amounts of commercial and industrial waste. Although
data for the latter is not as easily available as for municipal waste, it has
to be considered for the assessment of the total European waste incineration
Nevertheless, Waste-to-Energy overcapacities should be avoided. Careful
capacity planning is necessary and cooperation between the regions should be
