Why Zero Emissions?
We want to strengthen companies and help them on their way to a
sustainable future

2/3 of the costs in germancar manufacturing companiesare material costs!
To reduce theses costs meansstrengthening the companies,making them fit for a sustainable future and is theway to Zero Emissions!
…if you want to strengthen companies?

Traditional Production
Emissions are unused raw materials and they cause
Material costs
Operating costs
Personnel costs
Investment costs

Zero Emissions Production
Zero Emissions instead means
No disposal costs
Less costs for Material, Auxiliary materials, Operating materials
Less investment costs for environmental protection plants
Easier Public Authority Proceedings

Methods and Instruments
1. Step: EMA Workshop
EMA = Environmental Management Accounting
Institute for Resource Efficient and Sustainable Systems
Graz University of Technology
From Cleaner Production to Zero EmissionsMay 12, 2005
EMA – Environmental Management Acounting
EMA combines financial and physical data and calculates the environmental costs of companies
Physical data on material and energy input, material flows, products, waste and emissions
financial data on expenditures, costs, earnings, savings related to company activities with potential environmental aspects or impacts

What are Environmental Costs?
Total corporate environmental costs=
Costs of wasted capital and labour+
Costs of wasted material+
Environmental Protection Costs (Emission Treatment and Pollution Prevention)

ZEPRA – Balancing Software
1. Applicable to different companies
2. Quick calculation of variants to the existing process
3. A visual pleasing output 4. Be able to get results
without the exact knowledge of chemical reactions (rules of thumb, experimental data, experience)
5. Calculation of the composition of sludge to find possibilities for further use and for closing of water cycles or for removing valuable components
6. Easily adaptable to incorporate new
knowledge

Next Steps
At this time: Zero Emissions project with 7 companies
We want to proof, that it is
Technically and
Economically
possible to run three branches on Zero Emissions!
Branches are: Textile, Metal Treatment, Food
