Waste mapping

1. Waste mapping University College Northampton

2. Topic Overview • This training package covers: • How to identify sources of waste • Methodology of Waste Mapping • Basic principals of Waste minimisation • Useful tips and cost savings

3. What is waste mapping • Companies of all sizes underestimate the “true”costs of waste • All companies produce waste - even the efficient ones • Waste mapping is a recognised way to identify where waste is occurring and is often the first step towards tackling the problem

4. Why consider your workplace • It will reduce your overheads and increase your profitability • Improve environmental performance and enhance image with customers • Help your organisation comply with legislation • It will improve your workplace environment

5. How to start • Walk around site and identify sources of waste • Look for wastes that are produced at each stage of production from delivery to despatch • Start with the obvious and as these are dealt with other sources will become apparent • Produce a detailed site map to help indicate problem areas

6. 3 steps to successful mapping • Map where waste occurs and potential areas of waste • Do not forget items that seem peripheral • Get senior management commitment and talk to the employees who are involved in the process

7. Investigate your inputs and outputs • Everything you put in comes out somewhere • You need to know all your inputs, outputs and level of waste • Look at areas where the raw materials and the finished product are stored as well as the storage areas for the waste that is generated during the production process

8. Process Flow Diagram

9. Calculating the cost of waste • For ease of calculation it is necessary to convert to a common unit • Aim to measure first the total mass input to your process, then the mass output of good product and known wastes, and then find the difference • You then measure all the individual waste streams and try to account for all the loss

10. Identifying wasted resources • Raw materials and other consumables • Packaging • Solid - off cuts and defective products • Water / other liquids • Materials covered by Special Waste Regulations • Energy • Transport

11. Factors to be considered in prioritising strategy • The ease with which action can be taken • The easiest and lowest cost actions will usually be carried out first • The cost of a particular type of waste • The proportion being wasted • How any waste minimisation plan may affect production processes

12. What to do next • Go for it- but don’t forget to monitor progress. You need to “measure to manage” • Complete the map • Measure wastes produced • Calculate costs of waste • Work out action plan and implement it

13. Useful tips • Talk to all departments and appropriate employees • Involve senior management to help implement ideas • Set up company team • Listen to those who actually do the job • What is not used is waste

14. Use the help available • The potential cost savings and other benefits of waste mapping and waste minimisation are highlighted in a series of Good Practice Guides produced by Envirowise - These are available free through The Environment and Energy Helpline on: 0800 585 794 World wide web: http://www.etsu.com/etbp e-mail address: etbppenvhelp@aeat.co.uk

15. Updating and reviewing • As waste is tackled and reduced, the waste map will change • A regular review will enable you to see and record any genuine achievements made • Prioritise areas for further action
