4. FLOWING FROM THE NCPC
RESOURCE EFFICIENCY
& CLEANER PRODUCTION
AUDIT
CONDUCTED IN FEB 2015

5. AUDIT OBJECTIVES

6. • To ASSESS THE USAGE of ENERGY and WATER and
major consumers in the production process
(national energy efficiency targets)
• IDENTIFY opportunities for INCREASED EFFICIENCY
and RECOVERY of resources within these areas (target
driven)
• To evaluate/recommend EFFICIENCY MONITORING
PROGRAMMES

7. KEY FOCUS AREAS

8. • STEAM >50% REDUCTION
• ELECTRICAL ENERGY >20% REDUCTION
• WATER >50% REDUCTION (MUNIC SUPPLY)
TO STRENGTHEN OUR POSITION AS
INDUSTRY LEADERS in EFFICIENCY

9. • STEAM
• ELECTRICAL ENERGY
• SOLID WASTE
WATER
PRIORITISED IMPLEMENTATION OF
OZONATED WATER FILTRATION PLANT
WITH UV (MEMCON)

10. A LOOK AT THE REQUIREMENTS
Clean water prior to distribution to
municipal storm water drain
Water for applications throughout the
factory
For uses other than in end products
Suitable for end product for future
purposes

11. A LOOK AT THE SCIENCE
1 Factory effluent
enters effluent plant
and solids are
removed.
2 Water is filtrated in
effluent plant.
3 Blender mixes 25%
municipal and 75%
reworked filtered
water.
4 Ozonated filtration
removes bacteria.
5 Only 75% goes into
filtration plant where
it is ozonated into a
silo.
6 Goes through UV
system back into the
factory.

12. CAPEX R 2M
Projected 75%
reduction in
municipal water
supply
Projected annual
direct saving R
1.35M
Investment break-
even 18 months
IMPLEMENTED WATER FILTRATION SYSTEM – COST-BENEFIT
