cleaner production

14
Properly implemented CP :
usually
increases profitability lowers production costs enhances productivity provides a rapid return on any capital or operating investments required
10
Where are you now?
• 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
16
Properly implemented CP :
often
avoids regulatory compliance costs
leads to insurance savings
provides enhanced access to capital from financial institutions and lenders

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

Properly implemented CP :
always
• reduces long-term liabilities which companies can face many years after pollution has been generated or disposed at a given site

Cleaner Production Definition
“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.”
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.
• greenhouse loss
• hidden losses • leakage • non-conforming material • overfill • packaging • process loss • rework • second quality • stock loss • washings and etc.

What is waste?
There are literally hundreds words for different types of waste:
• allowance
• BOD • broke • contaminated solids • core loss • customer returns • damage • draining • dust • effluent • evaporation • furnace loss

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

Course Objective
At the completion of this course the participants will have understanding of :
Evolution of environmental strategies, concept of sustainable development Basic concepts of preventive environmental approaches
Prevention of Waste generation:
- Good housekeeping
- Input substitution - Better process control - Equipment modification - Technology change - On-site recovery/reuse - Production of a useful byproduct - Product modification
21
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
18
How CP could be applied in practice?
19
Cleaner Production practices
1. Good housekeeping
take appropriate managerial and operational actions to prevent: - leaks - spills
• 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
22
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
is fast and easy to implement
requires little capital investment
17
Cleaner Production principles
• precaution principle
• preventive principle
• integration principle

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