Passive environmental strategies Ignored or non recognized Environmental problem. Dilute & disperse Industrialist thought less apparent & less 4 harmful
Re-active environmental strategies End-of-pipe treatment Control of pollution & Waste Emergence of 5 regulations & laws
Constructive environmental strategies Development of environmental technology to loop back waste as process input Waste considered in product design & process Engineering On - site recycling & Recovery 6
Pro-active environmental strategies: Cleaner Production - Good housekeeping - Input substitution - Better process control - Equipment modification - Technology change - On-site recovery/reuse - Production of a useful byproduct - Product modification 7 Prevention of Pollution & Waste generation
CP versus End-of-Pipe approach Cleaner Production Pollution Control and Waste Management Continuous improvement One-off solutions to individual problems Progress towards use of closed loop or continuous cycle processes Processes result in waste materials for disposal ain pipeline with resources in and wastes out Everyone in the community has a role to play; partnerships are essential Solutions are developed by experts often in isolation 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 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 8
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 • greenhouse loss • hidden losses • leakage • non-conforming material • overfill • packaging • process loss • rework • second quality • stock loss • washings and etc. 9

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 • 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 14
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. ” (United Nations Environment Programme) 15
Cleaner Production Definition Continuous Products Preventive Integrated Processes STRATEGY for Services Humans Risk Reduction Environment 16
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 17
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 18
Properly implemented CP : 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 19
Cleaner Production principles • precaution principle • preventive principle • integration principle 20
Are you Energy Efficient? 1. Reduce energy and production costs 2. Improve environmental performance and reduce greenhouse gas emissions 3. Reduce exposure to rising energy prices and energy shortages 4. Win new customers who consider environment as an important selection criteria 21
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 22
What are the benefits of Cleaner Production? Improving environmental situation Increasing economical benefits Increasing productivity Continuous environmental improvement Gaining competitive advantage 23
How CP could be applied in practice? 24
Cleaner Production practices 1. Good housekeeping take appropriate managerial and operational actions to prevent: - leaks - spills - to enforce existing operational instructions 25
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 26
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 27
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 28
Cleaner Production practices 5. Technology change replacement of: - the technology - processing sequence - synthesis pathway in order to minimise waste and emission generation during production 29
Cleaner Production practices 6. On-site recovery/reuse - reuse of the wasted materials in the same process for another useful application within the company 30
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. 31
Cleaner Production practices 8. Product modification modify the product characteristics in order: - to minimise the environmental impacts of the product during or after its use (disposal) - to minimise the environmental impacts of its production 32
Cleaner Production procedures The recognized need to minimise waste The first step The second step The third step The fourth step Planning and Organization Assessment Phase Feasibility Analysis Phase Implementation Successfully implemented CP projects 33
1. Planning & Organization • Obtain management commitment • Identify potential barriers and solutions • Set plant-wide goals • Organize a project team 34
Team for CP success • Appoint CP Project Team: -Top Manager(MD), Vice Leader(Chief Engineer), Member (responsible Manager). Particular those responsible for business strategy, product development, plant operations and finance • Appoint Assessment team: -, Both departmental and supporting divisions, who play an important role in promoting CP • Appoint Facilitator: - who play an important role in disseminating information on good environmental practice 35
Leading. Team Role • Initiate & support CP assessment • Nominate assessment team • Set goal for assessment plan • Budget allocation for CP improvements • Manage CP option implementation • Reviewing CP progress Team Characteristics Motivated to improve efficiency Knowledgeable on waste prevention & energy efficiency Familiar on EP laws & regulations Understand on assessment process 36

CP barriers Internal to the companies: - - Lack of information and expertise Low environmental awareness Competing business priorities, in particular, the pressure for a short term profits Financial obstacles Lack of communication in firms Middle management inertia Labour force obstacles 38
CP barriers External to the companies: -Difficulty in The failure of existing regulatory approaches accessing cleaner technologies -Difficulty in accessing external finance 39
CP motivators and drivers Internal to the companies: - Improvements in productivity and competitiveness - Environmental management systems and continuous improvement - Environmental leadership - Corporate environmental reports - Environmental accounting 40
CP motivators and drivers External to the companies: - Innovative regulation - Economic incentives - Education and training - Buyer – supplier relations - Soft loans from Financial institutions - Community involvement - International trade incentives 41
CP Management Cycle 42
Pre-Assessment • Identify sources of waste • Draw process flow chart • Identify water, energy, material flow • survey on pollution & resource consumption • Select focus areas • Implement obvious options • Make assessment plan 43
Material and energy balances Heat Raw Materials Power The Industrial Process Cooling The Energy Balance Products & Waste The Mass Balance 44
Why are material and energy balances so important? 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 transporting waste • cost of solid wastes disposal • cost of pollution charges and penalties 45
Possible causes for waste generation Choice of Production Technology Choice & Quality of Input Materials Management Planning & Information Systems Technical Status of Equipment Process Personnel Skills & Motivation Product Specifications Process Efficiency Wastes & Emissions 46
CP assessment practices Good Housekeeping Equipment Modification On-site Recovery/ Reuse Input Substitution Process Production of Useful By-Product Better Process Control Technology Change Product Modification 47
Pre assessment work through • Investigate present status: - Historical data Base Line data Performance indicators Process flow charts • Performing on site investigation: • Compile input-output flow chart: • Selection of assessment focus: - Consider high potential for CP, high production cost, high waste - - Sequential approach (RM store-FG warehouse) Actual operation & Process control look at Supportive services too investigate Material handling methods & procedures considered Process monitoring points investigate Details of flows & quantities considered generation & high material and energy consumption 48
Pre assessment work through • Setting CP Targets: - SMART targets Challenging targets More on short term targets Few long term targets • Attend obvious options first • Develop assessment plan: - Like - Unnecessary lights - Spills & Leaks - Unmotivated personnel - Inadequate storage conditions - Inappropriate tools - Cross contaminations Include - Specify targets - Monitoring method - Majour activities - Responsibility of area - Expected output 49
Setting Objectives Short Term • Compliance • Improve Housekeeping • Improve Maintenance • Better Performance Long Term • Phase out toxic components • Introduce new product 50
