Why sustainable production?

• During the last decades, there was a clear
  evolution in the general attitude of governments
  and industry regarding protection of the
  environment in a positive sense
• Sustainable Production describes a preventative
  approach to environmental management
• It is a broad term that encompasses what some
  countries/institutions call eco-efficiency, waste
  minimisation, pollution prevention, or clean
  production, but it also includes something extra
• Sustainable Production refers to a mentality of
  how goods and services are produced with the
  minimum environmental impact under present
  technological and economic limits

Evolution of attitudes toward environmental issues
Passive environmental protection Negative
environmental impacts ? Regulatory
non-compliance ?
Active environmental protection Costly
end-of-pipe solutions ? Inefficient ?
Sustainable production Cost-effective ? R
egulatory compliance ? More efficient use of
raw materials and energy ?
Ref. Lanteigne et al. 2004

Sustainable products and processes is more than
technology

• The most common types of changes that are
  demonstrated by environmental improvements in
  industry are
• changes in the type, quality or quantity of
  resources used
• improved monitoring, maintenance or
  housekeeping
• equipment modification or substitution
• changes to processes, products and services.
• While these technical types of changes are
  indispensable, it is not enough by itself to
  bring sustainability in organisations.
• It is also about changing corporate culture and
  the attitudes of people.
• Great role of teachers and researchers!

Resources use optimization

• The goals of resources use optimization translate
  to waste prevention and minimization efforts in
  industry.
• The following research issues are addressed in
  our laboratory
• Waste minimisation in food industry
• Agro-chemical waste minimization
• Chemical utilization of CO2
• Reduction of emissions (VOC, particles)
• Waste mapping
• Waste management theory
• Motivation for waste minimization behaviour
• The effect of Environmental Management Systems on
  wastes
