Reasons for an environmental team

• Because there are many different
  departments/machines in a company, it is
  difficult to get the necessary overview and the
  detailed technological knowledge.
• Because there are motivated and competent
  employees in a company.
• Because as a TEAM with a common goal it is
  possible to work more efficiently than a lone
  ranger.
• Gather people from differnet departments
  production, maintenance, technology, purchasing,
  management, quality, accounting, research and
  development, environment, health and safety,
  legal branch, etc.

Material flow analysisDetailed description of
the material and energy use

• Which waste and emission streams are generated?
• Which raw materials are lost?
• Where and why does this happen?
• Where are the weak points?
• Where are potentials for improvement?
• Which materials can be reused?

9

• Within the production process, there are many
  points where materials and energy are lost.
• These points are also environmental and economic
  weak points.
• A material flowanalysis identifies the points
  where materials are lost and their amount.

10

• A comparison with the best available technology
  shows process weaknesses.
• The material flow analysis facilitates the
  evaluation of the "production costs" of waste and
  emissions.
• Eco-efficiencythe best use of materials reduces
  emissions.

Strategies for cleaner production
12
Product change

• Substitute the product
• Increase the product life-time
• Change the materials
• Change the product design
• Use recycled materials
• Avoid critical components

13
Good housekeeping

• Improve information
• Change dosage/concentration
• Increase the utilization of process capacities
• Check cleaning and maintenance period
• Foster standardization/automation
• Improve purchasing, storage and distribution
• Carry out a material flow analysis

14
Waste logistics

• Separation of waste and wastewater to
• Set up closed cycles
• Facilitate recovery and re-utilization
• Minimize quantities of hazardous waste
• Minimize disposal costs
• Minimize cleaning expenses (wastewater, exhaust
  gases, etc.)

15
Technological modification

• Substitute thermo-chemical processes by
  mechanical alternatives
• Use countercurrent cascades instead of
  single-static rinse techniques
• Manage separate waste and wastewater streams
• Improve process conditions
• Foster recovery and reuse of materials
• Increase life time of chemicals/materials
• Reduce the infiltration of impurities
• Ensure airtight sealing of equipment

16
Energy efficiencyTypical areas of improvement

• Cooling/refrigeration
• Heating
• Compressed air
• Insulation
• Heat recovery
• Separation processes
• Lighting
• ...

17
Internal recycling

• Reuse materials (solvents, etc.)
• Reuse materials for different purposes (paper,
  solvents for lower-quality use, e.g.
  pre-cleaning, etc.)
• Close internal loops (water)
• Use returnable systems (packaging materials)
• Reclaim materials with high value
