Summary

• Why Zero Emissions?
• What is Zero Emissions?
• Description of our methods and instruments to
  achieve Zero Emissions
• EMA Environmental Management Accounting
• ZEPRA Mass Balancing Software
• Data base for Experts
• Pinch Analysis for Energy Optimisation
• Case Studies

3
Why Zero Emissions?

• We want to strengthen companies and help them on
  their way to a sustainable future

Why reducing Emissions?
if you want to strengthen companies?
2/3 of the costs in german car manufacturing
companies are material costs! To reduce theses
costs means strengthening the companies, making
them fit for a sustainable future and is the way
to Zero Emissions!
6
Traditional Production

• Emissions are unused raw materials and they cause
• Material costs
• Operating costs
• Personnel costs
• Investment costs
• Public Authority Proceedings

7
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

8

• Methods and Instruments
• 1. Step EMA Workshop
• EMA Environmental Management Accounting

9
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

10
What are Environmental Costs?
11
EMA water related
12
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

13
Data base for experts

• solutions for waste water treatment
• decision support system
• support for consultants
• sustainable solutions (avoiding end of pipe
  decisions)

Case Study Wire manufacturing company
Before optimisation
After optimisation (calculated)
Implemented 35 reduction of water consumption
with no costs In implementation 17 reduction
of water consumption with low costs Starting in
Summer 10 reduction of water consumption with
low costs
19
Case Study Wire manufacturing
Next step Closing water cycles with in-house
equipment and implementing an effluent free
production!
Optimisation of HCl-ething bath in laboratory
scale Extension from 1 week up to 3 weeks
Testing different inhibitors

Anodising Company
Long term reduction of water consumption in an
anodising company

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
