WASTE & RESOURCE EFFICIENCY
Introduction
Rethink Waste Module 1: Slide 7 of 81
A quick introduction to waste – the facts
WASTE FACTS
• 600 million tonnes raw resources used by industry per year.
• On average 93% production materials are never used in the final product.
• 75 million tonnes of solid waste goes to landfill each year.
• Cost £15 billion per year.
• This is unsustainable, it’s uneconomic – we need to do something.
Rethink Waste Module 1: Slide 8 of 81
What is ‘resource efficiency’?
Looking at eliminating or reducing the use of materials or utilities (energy and water) to make a process more efficient or eliminating/reducing or recycling waste from that process.

Waste hierarchy
The Waste Framework Directive established the meaning of ‘Waste’ and the ‘Waste Hierarchy’. The hierarchy is a conceptual model for selecting waste management options.
Rethink Waste Module 1: Slide 10 of 81
What does it mean?
It is easy to gloss over the waste hierarchy without appreciating the meaning of
‘Eliminate’
‘Reduce’
‘Re-use’
‘Recycle’
‘Dispose’
Some examples of improvement options for each of the above for simple paper waste are highlighted in the next few slides together with details of the hidden costs you may incur if you do not apply these options…..
Rethink Waste Module 1: Slide 11 of 81

Become more resource efficient
All companies should aim to eliminate waste from the outset,
but if this is not practical or possible, then consider reducing,
re-using or recycling waste. If none of these options can apply,
then dispose of waste in a responsible manner.
Envirowise has produced the guidance leaflet ‘Become More Resource Efficient’ to enable businesses toprogress up the ‘waste hierarchy’ to reduce their waste and potentially achieve significant cost savings.

Denso video Case Study
It’s fashionable and easy to say ‘improve resource efficiency’ – but what does it really mean?
Envirowise has published a resource efficiency “Making More From Less” video case study for DENSO
Manufacturing UK Limited.
By applying a variety of waste reduction and re-use techniques to its
manufacturing plant DENSO realised significant cost and
environmental benefits including:
• £172,000 savings through energy efficiency improvements;
• £100,000 savings by introducing a pallet reuse/re-sale scheme;
• £5,000 reduction in hazardous waste disposal costs;
• 50% costs savings by amending lube oil supply method;
• 20% less hazardous waste generated.

WHY IT IS IMPORTANT FOR YOUR BUSINESS?
Drivers for Resource Efficiency
Rethink Waste Module 1: Slide 18 of 81
Why improve ‘resource efficiency’?
Looking at ‘resource efficiency’ will help you to:
• reduce the true cost of waste to your company;
• determine the baseline against which to judge the progress of your resource efficiency improvements;
• identify cost-effective opportunities to prevent and reduce waste;
• control your services/processes more effectively;
• set improvement objectives and targets;
• measure progress towards your targets and set new ones.
Rethink Waste Module 1: Slide 19 of 81
What are the drivers?
Reducing waste is not the only incentive to using resources efficiently.
The points below should also be considered:
1. company internal goals;
2. legislation;
3. costs;
4. reduce company’s environmental impact.
Let’s just have a quick look at each of these ….

Company internal goals
Implementing good environmental practice used to be considered a ‘fringe’ idea - now, most major
FTSE100 companies have environmental issues at the core of their business strategy because of:
• image;
• Corporate Social Responsibility;
• Environmental Management Systems (ISO 14001, Eco-Management and Audit Scheme [EMAS], BS8555 – Acorn/ Green Dragon/STEMS);
• pressure groups;
• marketing.
Rethink Waste Module 1: Slide 21 of 81
Legislation
The main pieces of legislation directly affecting the way companies use resources and dispose of wastes are:
Environmental Protection Act/Environmental Protection (Duty of Care) Regulations
Integrated Pollution Prevention and Control Directive (Environmental/PPC Permitting)
Producer Responsibility Obligations (Packaging Waste) Regulations/Packaging (Essential Requirements) Regulations
Hazardous/Special Waste Regulations
The Waste Electrical and Electronic Equipment Regulations
Batteries Directive
Rethink Waste Module 1: Slide 22 of 81
Costs
‘Resource Efficiency’ is not just an environmental initiative but an important business process that could
potentially save your organisation a lot of money.
Waste also costs money and by finding ways to reduce waste, your company could become more
profitable.
Did you know:
– that waste and badly used resources can account for over 4% of business turnover?
– that companies can save up to £1,000 per employee by tackling their use of resources?
– that most waste minimisation actions are simple low cost/no cost solutions?
Rethink Waste Module 1: Slide 23 of 81
Costs
The cost of waste is defined as:
‘The cost of purchasing, processing and disposing of all the non-product outputs’.
Improvements in resource efficiency will reduce waste and costs. Cost savings are probably the key
incentive to implement resource efficiency measures. Understanding the costs is important – and they are
often greater than immediately apparent….
Costs may be considered as ‘Direct’ and/or ‘Hidden’ costs.
THE TRUE COST OF WASTE

Direct costs
Examples of ‘direct’ costs include:
•waste handling storage and disposal costs;
•utilities cost;
•landfill Tax (currently 2009/10):
• £2.50/tonne (inert/inactive wastes);
• £40/tonne (all other wastes).
Together with actual disposal costs (eg transport, landfill charges etc) direct disposal costs can easily
amount to £100-120/tonne.
Rethink Waste Module 1: Slide 27 of 81
Direct costs – continue to rise!
The graph below shows the scheduled increase in landfill tax to 2014.
Rethink Waste Module 1: Slide 28 of 81
Hidden costs
Examples of ‘hidden’ or ‘indirect’ costs include:
•materials/energy;
•effort;
•added value – waste is not just the cost of discarded materials. It includes the cost of:
– wasted raw materials;
– rework;
– lost production time;
– excessive use of energy and water;
– loss of materials to atmosphere and to drain;
– waste treatment costs;
– wasted labour.

Pressure may come from internal or external sources to reduce environmental impact.
•Staff
•Pressure groups (e.g. Greenpeace/Friends of the Earth)
•Local residents
•Local authorities and planning
The Envirowise Indicator is an interactive web-based tool designed to allow all UK businesses, irrespective of their size or industry sector, to gain a useful indication of their company’s environmental impact and the financial savings that can be made by addressing it.

WASTE MAPPING Establishing Your Baseline
Rethink Waste Module 1: Slide 32 of 81
Understanding your site
Whether your site is large or small, it is often difficult to grasp the true ‘picture’ of waste – particularly when considering ‘waste’ in the wider context. An initial review to develop a ‘waste map’ can help in gathering basic information and understanding:
•Walk around your site looking for areas of waste and potential improvement;
•Take photographs;
•Talk to key people in all departments;
•Gather information on amounts and costs for raw materials, utilities and wastes;
•Estimate the potential savings associated with a few of the more promising opportunities to reduce resource use;
•Identify gaps in your data; and
•Start thinking about how to address them.
The following slides will take you through the process of developing a waste map. However, more detailed guidance is available in the Envirowise Guide ‘Waste Mapping: Your Route To More Profit’.
Rethink Waste Module 1: Slide 33 of 81
Who should I involve?
Where practicable, it is best to consult a team that includes:
1. the environmental, quality, health and safety manager(s);
2. the manufacturing and product development manager(s);
3. appropriate shop-floor staff (who often know the process best);
4. the procurement and purchasing manager(s);
5. suppliers and customers.
Rethink Waste Module 1: Slide 34 of 81
Getting staff involved
Key to getting peer buy-in to your ‘resource efficiency’ improvement is involvement and
empowerment.
The points below are things you should consider:
• Involvement – eg brainstorming sessions.
• Create a positive climate to identify opportunities.
• Develop new performance measures.
• Encourage thoughts about environmental effects.
• Important message to get across is ‘How will they benefit?’.
Rethink Waste Module 1: Slide 35 of 81
Brainstorming
Often brainstorming descends into a situation where only the extrovert (or thick-skinned!) get to
put forward their ideas. During your brainstorming sessions establish rules such as:
• No criticism or debate/editing;
• Be creative (encourage wild or exaggerated ideas);
• Quantity rather than quality;
• Build on and combine ideas.
To ensure you obtain all contributions (whatever they may be and from whomever) make sure:
• everyone has a chance to participate;
• everyone is thinking about the same problem;
• all ideas are encouraged;
• all ideas are recorded.
Otherwise it’s not brainstorming!
Rethink Waste Module 1: Slide 36 of 81
What should I look out for?
Particularly wasteful processes, such as:
• off-cuts or discarded packaging;
• water running down the drains;
• unnecessary heating or lighting.
Start by noting the obvious. Look into less obvious wastes later.
A checklist is available to help you
Waste Checklist
Rethink Waste Module 1: Slide 37 of 81
What do I do with all this information?
Develop a ‘waste map’!
It’s not complicated and a waste map will allow you to manage the majority of the information you gather in a clear and explanatory way.
The only exception may be costs.
Costs may not ‘fit’ exactly on a waste map – they may apply to a collection of wastes or be a bill for site wide supply. If costs cannot be entered on a waste map keep the information available elsewhere –
perhaps start a cost file.
To develop a waste map we recommend that you initially produce a flow chart representing your site activities so you can assign all the information you find to the relevant area or department.

What should I include?
Identify the main inputs and outputs.
Start by including your:
• Material flows - this includes all raw materials – not just those to make the product.
• Utilities used
• Wastes produced - include all those items which may be ‘recycled’ e.g. metals, pallets etc
• Liquid and gaseous emissions produced
Present this information visually on the waste map for the site.

Additional information to collect
When gathering information about the site and the processes which may benefit from improved resource
efficiency you may also wish to consider the following:
• Take photos of what you see (it will act as an aide memoir later on).
• Talk to staff to identify the cause of wastes if it is not obvious and record a summary of your discussions.
• Record any unusual occurrences of wastes.
• Estimate quantities and costs - don’t worry if you can’t be accurate.
• Use common units and time frames to record inputs, outputs and wastes - It may be easier to annualise.
Don’t get distracted too much at this stage!
Rethink Waste Module 1: Slide 57 of 81
FINDING, RECORDING AND USING YOUR DATA
Using Your Data Effectively
Rethink Waste Module 1: Slide 58 of 81
OK – so what do I do then?
Once you have a waste map you can then populate your waste map with data:
• quantities of materials used;
• utilities consumed (gas/water/electricity);
• quantities of wastes generated;
• costs (if possible).
Remember this information is important –
What you cannot measure you cannot manage!
Rethink Waste Module 1: Slide 59 of 81
Tip - How to express data
So that you can make comparisons and make it easy to understand the data you obtain, it is
recommended that you use common units of measurement and quantification.
Common examples include:
Raw materials (tonnes/year)
Water use and effluent (m3/year)
Gas and electricity (kWh/year)
Fuel use (litres/year)
Solid waste (tonnes/year)
Solvent use and emissions (tonnes/year)
Rejects (number/year, % of produced)
Rethink Waste Module 1: Slide 60 of 81
Data collection
Where can you get the data to quantify the inputs and outputs for your waste map? Possibly from one
or more of the following:
• Bills from suppliers of materials/utilities;
• Material use reports;
• Production statistics;
• By-product and waste disposal records;
• Actual measurements;
• Empirical calculations
− If the weight of waste is not known then the size of the container multiplied by the density will suffice;
• Plant rated capacities etc;
• Customers and suppliers.
Rethink Waste Module 1: Slide 61 of 81
Where else can I obtain data?
Start by measuring your key raw materials and utilities, then measure the resources highlighted as significant during your waste mapping exercise.

Watch out for data errors!
As well as indicating the material and waste flows you need to measure, your waste map will help you to
identify:
• Weigh/count delivery quantities
• Standard conversion factors which are often incorporated into process descriptions eg 10kg of raw material ‘X’ always gives 50m2 of product ‘Y’
• Hidden materials eg consumables used for Health & Safety purposes, materials used during maintenance etc
• Use of financial data that are not necessarily linked to consumption
You may find that some of the historical assumptions that have been made are wrong!
Rethink Waste Module 1: Slide 70 of 81
Use of data – baseline and benchmarking
Once obtained, the data in your ‘waste map’ provides you with your baseline. This will enable you to establish your baseline and benchmark your site:
Baseline = Where you are now and a point from where improvements (or otherwise!) can be gauged
Benchmark = Where you are compared to your peers – usually compared against the same manufacturing sector
Both parameters are important in undertaking any ‘Measuring to Manage’ activity. Looking back at your baseline helps you to see how you are progressing and benchmarking your performance helps you to see how you fare compared to others.
Envirowise has produced some guides which provide further information on ‘Measuring to Manage’
Measuring to Manage : How reducing waste can unlock hidden profits
Measuring to Manage : A ‘How To’ Guide
Measuring to Manage: The key to reducing waste costs
Further information on baseline and benchmarking is given in Module 3.

Preparing a ‘waste map’ for your site
Remember - the key things you need to look at to ‘map’ your process:
Rethink Waste Module 1: Slide 73 of 81
What have you learnt so far?
By getting this far into rethink waste you should:
• Have an awareness of materials and utilities used;
• Know how to complete a waste map;
• Be aware of the information needed to populate your waste map including:
- Main materials and utilities used for each process;
- Wastes leaving the process;
- Ideally, some of above quantified and costed.

Suggested next steps…
From the information in Module 1, consider the following points as your next key steps towards
‘Rethinking waste’:
• Quickly think about your site, complete a review
• Sketch down the individual process areas that would compose a ‘waste map’
• Jot down where information on materials and utilities in, and wastes out, may be available from within your organisation
• Prepare your first ‘waste map’.

Gaining support and commitment
To undertake resource efficiency improvements usually requires commitment from senior management to
facilitate the availability of resources and to get support from colleagues. It is often difficult to get management commitment without being ‘armed with some knowledge’ – particularly details of the potential savings that can be made.
• Try to explain that the initial review is not just paperwork and that it will probably identify and bring about realistic changes that will save both resources and money.
• If you can, during the review gain some facts and figures on some ‘quick wins’ you may be able to achieve.
Further information on gaining support and commitment is provided in Module 3 - after the initial review
has been undertaken.

Module 1 has introduced you to the important concepts of data collection and waste mapping.Through this module we hope you have achieved an awareness of the …
• Principles of resource efficiency;
• Likely benefits resource efficiency can bring;
• Type of data required to establish your baseline;
• Importance of true costs (particularly added value);
• Concept of presenting data in a ‘waste map’ format.
Two key templates are provided to help you.
If you have not used them, download them now and completeboth templates before module 2.
If you are short of time, focus on one area of your business.

Defra has produced ‘The environment in your pocket 2008’, which
focuses strongly on the theme of climate change.
‘The Environment in your Pocket’ is a handy, free of charge,
pocket-sized distillation of around 60 key data series largely
from the ‘e-Digest of Environmental Statistics’ website.
Its aim is to make environmental statistics
accessible to wider and different audiences.

Further Reading
There is growing international recognition that current patterns of consumption and production are
unsustainable.
The EEF, with support from Barclays Commercial,
has produced a 'Sustainable Resource Management’
publication to support manufacturers in moving forward
on resource efficiency.
The document provides an overview
of the key issues and questions as well
as highlighting examples of best practice.
