Solid Waste Management SIA
First results:
The following figures show examples of results from
CO 2
-calculations related to different scenarios of green
waste recovery. Two time frames are considered: 2
years and 50 years. After 50 years the biomass used
for the recovery is renewed (growing of plants). It is
illustrated a positive balance for the energy recovery
of raw green waste from spring. The energy recovery
for conditioned green waste (screening) is much more
efficient and has a similar dimension as the CO 2
-balance
for the substitution of german peat by substrates
from green waste compost.
Conclusion:
Both scenarios for the recovery of green waste lead
to a reduction of greenhouse gas emissions, although
with varying efficiency. Significant savings result from
energy recovery as well as from material recovery (similar
dimension). Therefore a similar or even equal
political treatment – e.g. basing on saved greenhouse
gases - is reasonable. The investigation project will
also deliver a database and the parameters to provide
a basis for future political decisions.

Cooperation with the Universidad Católica Boliviana
« San Pablo », in La Paz, Bolivia
In collaboration between the Department
of Civil Engineering of
the Universidad Católica Boliviana
and the Institute of Sanitary
Engineering, Water Quality and
Waste Management of the University
of Stuttgart, an exchange
of know-how and information is
taking place in all the fields of
environmental technology and
environmental analysis with a focus on waste management.
This cooperation developed on the basis of the
EU project WasteNet, which is going to be continued
in other fields, including student exchange to carry out
Bachelor and Master Thesis. In addition to this, block
courses will be offered in La Paz for several degree
courses in the fields of environmental engineering and
environmental analysis. An intensive know-how exchange
is taking place with regards to biological waste
treatment with emphasis on digestion plants. Other
priorities include the recycling of waste tires, mining
waste, hazardous household waste and the recovery
and treatment of electrical and electronic wastes.
