• customer returns
• damage
• draining
• dust
• effluent
• evaporation
• furnace loss

9. Waste is waste what
ever you call it : take
the opportunity to cut
waste and increase
profits!

Cleaner Production Financing
The “Cost of Waste” Iceberg
THE HIDDEN COST
OF WASTE
Adapted from: Bierma, TJ., F.L. Waterstaraat, and J. Ostrosky. 1998. “Chapter 13: Shared Savings and
Environmental Management Accounting,” from The Green Bottom Line. Greenleaf Publishing:England.

11. Where are you now?
11
• Only a change
in technology
would eliminate
waste
completely
• We are
optimising our
processes and
achieving big
cost reductions
• Waste is
coming down as
we change the
way we work
• We have
identified our
waste and
monitoring it
• We plan to
reduce waste
• Waste is cost
and regulatory
issue
• Waste is only
disposal issue
• Waste is not an
issue

12. Cleaner Production Definition
12
“The continuous application of an integrated
preventive environmental strategy applied to
processes, products, and services to increase
overall efficiency and reduce risks to humans
and the environment.”
(United Nations Environment Programme)

Properly implemented CP :

15. Properly implemented CP :
usually
 increases profitability
 lowers production costs
 enhances productivity
 provides a rapid return on any capital or
operating investments required
 increases product yield
 leads to the more efficient use of energy
and raw materials
15

16. usually (continuation)
 results in improved product quality
 increases staff motivation
 relies on active worker participation in
idea generation and implementation
 reduces consumer risks
 reduces the risk of environmental
accidents
 is supported by employees, local
communities, customers and the public
16
Properly implemented CP :

17. often
 avoids regulatory compliance
costs
 leads to insurance savings
 provides enhanced access to
capital from financial
institutions and lenders
 is fast and easy to implement
 requires little capital
investment
17
Properly implemented CP :

18. Cleaner Production principles
 precaution principle
 preventive principle
 integration principle

19. How CP could be applied in
practice?
19

20. Cleaner Production
practices
1. Good housekeeping
take appropriate managerial and
operational actions to prevent:
 leaks
 spills
 to enforce existing
operational instructions
20

21. Cleaner Production
practices
2. Input substitution
 substitute input materials
 by less toxic
 or by renewable materials
 or by adjunct materials
which have a longer
service life-time in
production
21

22. Cleaner Production
practices
3. Better process control
modify:
 operational procedures
 equipment instructions
and process record keeping in
order to run the processes more
efficiently and at lower waste
and emission generation rates
22

23. Cleaner Production
practices
4. Equipment modification
modify the existing production
equipment and utilities in order;
- run the processes at higher
efficiency
- lower waste and emission
generation rates
23

24. Cleaner Production
practices
5. Technology change
Replace;
- the technology
- processing sequence
- synthesis pathway
in order to minimise waste and
emission generation during
production
24

25. Cleaner Production
practices
6. On-site recovery/reuse
- reuse of the wasted materials in
the same process for another
useful application within the
company
25

26. Cleaner Production
practices
7. Production of a useful by-product
consider transforming waste into
a useful by-product, to be sold
as input for companies in
different business sectors
26

27. Cleaner Production
practices
8. Product Modification
modify the product haracteristics
in order;
- to minimise the environmental
impacts of the product during or
after its use (disposal)
- to minimize the environmental
impacts of its production
27

28. CP versus End-of-Pipe approach
28
Cleaner Production
Continuous improvement
Progress towards use of closed loop
or continuous cycle processes
Everyone in the community has a
role to play; partnerships are
essential
Active anticipation and avoidance of
pollution and waste
Elimination of environmental
problems at their source
Involves new practices, attitudes
and management techniques and
stimulates technical advances
Pollution Control and Waste
Management
One-off solutions to individual
problems
Processes result in waste materials
for disposal a pipeline with
resources in and wastes out
Solutions are developed by experts
often in isolation
Reactive responses to pollution and
waste after they are created
Pollutants are controlled by waste
treatment equipment and methods
Relies mainly on technical
improvements to existing
technologies

29. What is not CP?
Off-site recycling
Transferring hazardous wastes
Waste treatment
Concentrating hazardous or toxic
constituents to reduce volume
Diluting constituents to reduce hazard or
toxicity

awareness
- Competing business
priorities, in particular, the
pressure for a short term
profits

41. Why are material and energy
balances so important?
41
The material and energy balances are not only
used to identify the inputs and outputs of mass
and energy but their economic significance is
related to costs, such as:
• cost of raw material in waste
• cost of final product in waste
• cost of energy losses
• cost of handling waste
• cost of handling waste
• cost of transporting waste
• cost of solid wastes disposal
• cost of pollution charges and penalties

43. Option generation (1)
 Creative Problem Solving (CPS):
- Find facts
- Identify the problem
- Generate ideas to solve the problems
- Define criteria to be used to select solutions/ideas
 Screening of ideas / options:
- Select all ideas/options that may be implemented immediately
- The remaining options/ideas should then be divided into three boxes:
- Good housekeeping
- Interesting options but more analysis is needed
- Waiting box + Rejected
 Weighted sum method to prioritise options in second group:
- What are the main benefits to be gained by implementing this option?
- Does the necessary technology exist to implement the option?
- How much does it cost? Does it appear to be cost effective, meriting in depth economic
feasibility assessment?
- Can the option be implemented within a reasonable timeframe without disrupting
production?
43

44. Option generation (2)
Traditional brainstorming
44
• Formulate problem (problem
identification)
• Define objective of the
brainstorming session
• Follow the rules of brainstorming:
- Select a secretary to write down
all ideas (The secretary can't take
part in the idea generation)
- Select a group leader (the group
leader shall control that the four
main rules are followed)
• Close the idea generation after
30-40 minutes

• Preliminary evaluation
• Technical evaluation
• Economic evaluation
• Environmental evaluation
• Selection of feasible options

47. Payback Period
- period of time (years) needed to
generate enough cash flow to
recover the initial investment
47
Capital investment
Annual operating cost savings
Payback period = _____________________________

48. Implementation & Continuation
48
• Prepare a CP plan
• Implement feasible CP measures
• Monitor CP progress
• Sustain Cleaner Production

49. 49
CP attacks the problem at several levels
at once. The implementation of an
industry/plant level program requires,
- the commitment of top
management
- a systematic approach to
CP in all aspects of the
production processes

51. CP and main stakeholders
51

52. How can governments
promote CP?
 Applying regulations
 Using economic instruments
 Providing support measures
 Obtaining external assistance
52

53. CP applicability for local
governments
 Corporate decision-making
 Local environmental management
strategies
 Community and industry partnerships
 Sustainable economic development
 Public environmental education
 Specific local environmental problems
 Local environmental monitoring
53

54. CP and financial institutions
Environmental evaluation can help:
54
•Establish an exclusion list
•Identify environmental
risks in every project
•Understand the financial
institution’s exposure to
environmental risks and
liabilities
•Monitor the environmental
risks of transactions and
respond
•Evaluate risks and
liabilities in foreclosure or
re-structuring activities

55. What are the benefits of Cleaner
Production?
Financial advantages:
Usually a short Payback Period (sometimes in
months)
Many low-cost options
Quick to implement
Improved cash flows
Greater shareholder value
Better access to capital and appeal to financial
institutions
Inherent preventive approach leads to insurance
savings

57. Main factors affecting
exposure to
environmentally-derived
risks  The nature of environmental
risks inherent in business
activity of the client
 The size and term of, and the
security for, the transaction
 The client’s ability and
commitment to adequately
manage these risks
57

58. If a CP project is presented to a financial
institution, it should be clear that the company
already undertook voluntary actions aimed at;
 rationalising the use of raw materials, water and energy
inputs, reducing the loss of valuable material inputs and
therefore reducing operational costs
 reducing the volume and/or toxicity of waste, wastewater
and emissions related to production
 improving working conditions and occupational safety in a
company
 making organizational improvements
 improving environmental performance by the
implementation of no-cost and low-cost measures from the
company’s funds
 reusing and/or recycling the maximum of primary inputs
and packaging materials
58

59. Environmental investment
opportunities
 loans to enterprises to finance required or
desired investments in technologies
resulting in direct and indirect
environmental benefits
 loans to municipalities to finance
investments in environmental
infrastructure
 loan guarantees to both enterprises and
municipalities for “soft” credits from
national or regional environmental funds
for environmental investments
 loans to finance businesses providing
environmental goods and services
59

60. What have we learned?
 The CP approach reduces pollutant generation at every stage of
the production process
 CP can be achieved through:
- good operating practices
- process modification
- technology changes
- raw material substitution
- redesign and/or reformulation of product
 The economic advantages of CP are:
- cost effectiveness
- increased process efficiency
- improved product quality and enterprise competitiveness
- cost of final treatment and disposal is minimized
 Effluent treatment, incineration, and waste recycling outside
the production process are not regarded as CP
60

61. Broader application of CP
CP is closely linked to:
• Environmental Management Systems
• Total Quality Management
• Health and Safety Management

“An understanding of
the business value to be
gained from efficient use
of natural resources is an
important first step
toward sustainability:
toward building a world in which resources
are managed to meet the needs of all
people now and in the future.”
(J. Lash, President of
the World Resources Institute)
