Why be resource efficient?
• savings in costs
• reduced levels of waste (raw materials, product,
energy, water, etc)• improved products, packaging and processes• reduced levels of pollution• resources used more efficiently• increased profitability• improved environmental performance• helped to comply with legislation• helped towards suitable accreditation• improved level of sustainability

What do you need to do?
• WHAT• Understand your waste streams
• – consider water, energy and other wastes
• Understand what resources you use
• Understand your suppliers
• Use a ‘fresh pair of eyes’
• HOW• Conduct a walk-around survey
• Map your wastes
• Flow chart
• Diagnose and Prioritise

Some Practical Tips
A FACTORY / PROCESS ENVIRONMENT
Improve Housekeeping
Segregate to reduce costs
Recover washings (pump / filter tank)
Don’t over order materials
Store more liquids in bulk
Schedule production to minimise washing
Recover or reuse vessel washing liquors
Some Practical Tips
AN OFFICE ENVIRONMENT – It’s Simple
Using both sides cuts paper use by 50%
Cancel junk mail
Use electronic communication
Avoid overproduction of marketing material
Choose minimally packaged products
Hold an annual ‘stationary amnesty’ or ‘one bin day’
Turn off taps fully / fit push button taps
Check pipes for leaks
Switch off and replace with energy efficient
Travel planning
Case studiesLots of examples
Wilson’s Country
• Established in mid 1980’s• Pack potatoes and fresh fruit• 120 employees• £5m new facility Carn Road Industrial Estate (2005)
Achievements
• Investors in People (IIP)• BRC (Higher Level)• Wilson’s Country Garden
Potatoes voted Top 10 ‘Tesco’s Customers favourite brands’
• No additives or preservatives used
WASH PEEL CUT PACK
Envirowise Visit (FTV)Issues Highlighted
WATER USE / DISCHARGE• Approx 80% water used in washing
• 5 automated washers – 2 with leaks
• Cleaning Efficiencies
• Dirty water dumps (timed) – not in line with production quantities
• No water re-use or recycling
• Old ETP
Envirowise FTVIssues (cont)
SOLID WASTE• Segregation of wood & green waste only• Volumes of waste in skips• Waste created at packaging brand changeover
MANAGEMENT• Scheduling of repairs• Cleaning of drainage channels (sweepings)
Action Plan (1)
1. Better Leak ManagementMinimal Cost : Payback <6 monthsSavings – for every 1m3 = £1.59 saved (estimated that £133 could be saved in 24 hours)
2. Reduce Dirty Water Dumps – dependent on volumes washedMinimal Cost : Payback <6 monthsSavings – as for leak management
3. Recycle / Re-Use Water in processHigh Costs : New ETP with payback>24 months Savings of £47,000 – if 50% recycled
Action Plan (2)4. Segregate Waste
Minimal Cost : Short Payback <6 months (receptacles)Savings – Cardboard = £19,000 & Plastic = £10,000
5. CompactionModerate Cost : Medium Payback 6 – 24 monthsSavings – dependent upon new compacted size. Less skips lifted.
6. Reduce brand changeoversMinimal Cost – scheduling / programmingSavings two fold – reduced volumes of material used (purchased) and reduced number of skip lifts
7. Reduce effluent strengthMinimal cost – cleaning regime changesSavings in reduction in effluent load – Mogden formula charges for BOD and Suspended solids.

Issues & Solutions (1)Envirowise Intervention – KREEC II
1. Packaging MaterialChange from use of screws and fixings in small quantities – to a consignment stock operationSavings - reduced cardboard and plastic wasteCapital Costs – low
2. Waste Monitoring & TargetingSet KPI’s eg. wastes per unit. Smarter purchasing choices eg. wood in desired lengths.Savings – reduced off cuts (up to £20,000)Capital Costs – low (discuss with supplier)
3. Production / Utilities Monitoring & TargetingPractice electricity conservation measuresSub-meteringSavings – through greater efficienciesCapital Costs - Low
Issues & Solutions (2)Envirowise Intervention – KREEC II
4. Value Engineering
Consider design elements – floor bracing & window cut outs
Savings – up to 5% of total steel costs (and same for wood)
Capital Costs – Medium (review of nesting / cutting)
5. Housekeeping
Improve stock rotation, segregation and use up ‘odds’
Savings - £2,000
Capital Costs – Nil
6. Compressed Air
Introduce inspection system and maintain airlines to reduce leaks
Savings - £1,000
Capital Costs - Nil
