Reducing production cost and
therefore reduction of waste.
Providing incentives to workers
who reduce waste – rewards,
recognition.
Providing the necessary training
to workers
The owner and manager must
be serious about …

TRAINING OF
WORKERS

Training the workers in Identifying and managing wastes.
Recognising that there is a cost associated with producing wastes
Different ways of reducing wastes.
At the very least – training in good housekeeping practices
![Page 8: Modules 5&6 June 3, 2013 Malolos City · PDF fileprocess units – production, ... •The percentage of goods going directly from production to disposal ... AMONG FIRMS CLEANER PRODUCTION](https://reader031.vdocuments.us/reader031/viewer/2022030419/5aa5b2a87f8b9afa758d97bf/html5/thumbnails/8.jpg)
GOOD HOUSEKEEPING
PRACTICES - examples Minimise spills and leaks Improve operating practices Adequate and proper storage of materials

Keeping containers closed and
in a secure place.
Ensuring that all containers are
properly labeled (content, date,
etc.)
Having different containers for,
i.e., not mixing, different wastes
Why does the following constitute
good business practice?

• Identify the main processes and the most wasteful
process units – production, material handling &
storage, uitilies, etc
• Identify inputs and outputs – collect necessary data
• Prepare flow charts
• Establish material, water and energy balances
• Identify critical points in terms of financial
viability, environmental impacts and quality control.

• Raw materials usage and costs
• Production quantities and sales revenue
• Quantities of wastes generated in each unit
operation if possible
• Labour costs
• Utilities consumption and costs
• Environmental and labour compliance costs
This baseline is important for evaluating and.
selecting the best CP options

STANDARDS for developing flow charts
Integrity – all revelant environmmental impacts of the operations should be listed. Transparency /objectivity – All the flow of materials and energy should be registered objectively Continuity – time period should be equal for all the areas (e.g., 1 yr) Practicality/efficiency – to utilise all resources (time personnel, expenditures) register only the material and energy that are ecologically relevant Confidence – the data collected should lead to plausible results Clarity – The results are unequivocal and useful from the perspective of decision making.

protects the ecological balance and creates economic sufficiency.”
• the replacement of the current economic order of inequity, destruction and greed that has kept half of the global people in poverty and created a potential climate catastrophe.”
• The core idea of a GE should be to enforce Sustainability as in wellbeing of all people and biodiversity.

• decoupling of production and environmental degradation
• Environmental degradation = fcn (Pollution or waste per GDP x GDP/capita x Population)
This decoupling is possible ONLY through industrial ecology and cleaner production

• The percentage of goods going directly from
production to disposal (i.e., single-use products)
is reaching 30% in some sectors
• For many products, the number of goods thrown
away is comparable to the number of goods
sold, indicating a substitution, rather than an
increase in wealth
• Technological progress is still focused on
production not on utilisation 43

1. It is a systematic, comprehensive, integrated view of all the components of the industrial economy and their relationship with the biosphere
2. Emphasizes the complex patterns of material flows both within and outside of the industrial system RATHER than in terms of abstract monetary units or energy flows
3. Technological dynamics and development is a crucial, but not exclusive, element to achieve viable and sustainable industrial economic systems
IT IS BASED WITH CLOSING THE LOOPS
AMONG FIRMS
CLEANER PRODUCTION CLOSES THE LOOPS WITHIN.

“... involves designing industrial infrastructures as
if they were a series of interlocking man-made
ecosystems interfacing with the natural global
ecosystem.” (H. Tibbs, Industrial Ecology - An Environmental
Agenda for Industry, 1993)
These interlocking ecosystems can be
defined/bounded at three levels – material, sector,
spatial (region/estate)

A co-operative approach can result in significant reductions in
environmental impacts … and save money.
The Symbiosis essentially « organised itself » over a long period of
time using sound financial criteria to decide on projects BUT
INITIALLY TRIGGERED (and sustained) BY POLICY.
Confidence was built between partners, resulting in long-term
contracts to supply « wastes » to each other.
The close proximity of partners has helped to reduce investment
costs for infrastructure (e.g. pipelines etc.)
The proximity and the social relations among the human partners -
crucial in developing co-operation (socio-cultural factors) and reducing
transaction costs.
Creation of a working group to follow the development of projects is
very important (e.g. Symbiosis Institute, 1996)
