1 Resource efficiency: cut costs in plastics processing Workbook 4: operating resource efficiency

2 The greatest waste is the waste we don’t see Not: stop waste! But: find waste! Operating resource efficiency1

3 Business pressures for resource efficiency Waste costs real money The true cost of resource inefficiency and waste is hidden Resource efficiency is good business Legislation and the legal consequences Our reputation and customer pressure Operating resource efficiency2

4 Words for waste Operating resource efficiency3 Conveyor loss, customer returns … Defects, dirty solvent, dregs, dross, dust... Obsolete stock, offcuts, out-of-spec, overfill … Reel ends, regrind, rejects, rework, rubbish … Scrap, second quality, sprues, sweepings … Usage allowance, usage variance... Workaway, yield loss... + more that are being invented all the time

5 Where to find waste? Incoming materials Storage (raw materials, parts, finished products) Production Support services Energy Water Other Operating resource efficiency4

6 What to do with waste? Eliminate it Best and cheapest Reduce it Re-use it Recycle it Dispose of it Worst and most costly Operating resource efficiency5

7 Process flow sheet Operating resource efficiency6 Lubricants Plastics processing Labour Heating and lighting Utilities Storage Packing and warehousing Rejected material Dirty oil Wasted time Transit packaging Release agents Purging materials Cleaning materials Sprues and runners Tops and tails Heat OTHER INPUTS OTHER OUTPUTS MAJOR INPUT MAJOR OUTPUT

8 Method waste Operating resource efficiency7 Moving Storing Plastics processing Counting Inspecting Scrapping Reworking Assembling Sorting Activity Add value Add cost (waste)

9 The five whys Get to the root cause of a problem Ask ‘why’ at least five times Remove the root causes - not just the visible symptoms Operating resource efficiency8

10 Cause and effect diagram (the Ms) Operating resource efficiency9 EnvironmentMachinesMaterials MenMeasuresMethods Effect

11 How to reduce material waste Take action in the following areas: Materials management Waste management Energy management Water management Packaging management Other measures Operating resource efficiency10

12 How to reduce method waste Reduce stocks and work-in-progress Improve worker involvement and quality Increase flexibility and productivity Choose the best machinery Reduce lead times dramatically Add value not cost Improve workflow Operating resource efficiency11

13 Potential opportunities Operating resource efficiency12

14 Potential opportunity analysis What is the real cause of the concern? What information is needed? What are the available sources of information? What do we need to fill in the gaps? How are we going to get it? Operating resource efficiency13

15 Operator contributions Vital understanding of how processes actually work Day-to-day contact with the process Hands-on ability to reduce waste and improve resource efficiency Operating resource efficiency14

16 Operator opportunities Contribute to the business Increase job satisfaction Gain experience in problem solving Increase understanding of their job Operating resource efficiency15
