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’

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 studies
Lots 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

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 FTV
Issues (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 Management
Minimal Cost : Payback <6 months
Savings – for every 1m3 = £1.59 saved (estimated that £133 could be
saved in 24 hours)
2. Reduce Dirty Water Dumps – dependent on volumes washed
Minimal Cost : Payback <6 months
Savings – as for leak management
3. Recycle / Re-Use Water in process
High 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. Compaction
Moderate Cost : Medium Payback 6 – 24 months
Savings – dependent upon new compacted size. Less skips lifted.
6. Reduce brand changeovers
Minimal Cost – scheduling / programming
Savings two fold – reduced volumes of material used (purchased) and reduced
number of skip lifts
7. Reduce effluent strength
Minimal cost – cleaning regime changes
Savings in reduction in effluent load – Mogden formula charges for BOD and
Suspended solids.
C=R+V+Vb+B(Ot)+S(St)
TOTAL SAVINGS
At least
£76,000

Issues & Solutions (1)
Envirowise Intervention – KREEC II
1. Packaging Material
Change from use of screws and fixings in small quantities – to a consignment
stock operation
Savings - reduced cardboard and plastic waste
Capital Costs – low
2. Waste Monitoring & Targeting
Set 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 & Targeting
Practice electricity conservation measures
Sub-metering
Savings – through greater efficiencies
Capital 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
TOTAL SAVINGS
£52,556
+ 5% steel costs
