Solid Waste in Penang Island




Estimate is 1.1 kg of solid waste per person generated in Penang
2009 - 726 tons per day dumped into landfill in Penang Island or 265,000 tons per year
Household waste about 70% of total waste
Organic waste about 45% of total waste i.e.

MPPP- Solid Waste Disposed

Expenditure for SWM-2009





Real Expenditure including salaries was
RM 87 million or 38% of budget; of which
Waste collection – RM 20.4m
Transfer costs 7.6m
Tipping Fees -
Total
5.0m
32.0m (15%)

Other costs of Solid Waste
Disposal



Environmental pollution - release of
Methane, CO2, leaching > global warming
Unhygienic and spread of disease – smell, roaches, rats
Destruction of environment – running out of landfill

Increasing costs of Solid
Waste Disposal

Concept & Benefits of Waste




Divert Solid Waste from SOURCE thru
Segregation > reuse, recycle, regenerate
Reduce cost of waste collection and disposal

Richness from Waste






Instead of throwing away organic waste
– compost or turn it into fertilizer
Complete the natural process of turning waste food into food
Earn income from fertilizer
Organic fertilizer – food is chemical free
Soil and Environment is richer
Life is richer

Methods-
Compost,
Bio- regen

Bio-Regen Machine Used in
PSDC
16

How Does Bio-Regen Machine
Work





Feed organic food waste into machine
Water and Bokashi (enzyme) are added
Grinder process and liquidize the food
Liquid pumped into container
Stored in container for 1 month - waste turns into liquid fertilizer (1,000 litre) thru organic process that reduces CO2
17

Estimated Cost of Waste Disposal to
Pulau Burong per ton (excld salaries)




Estimate current cost - RM 150 per ton
Long-term average costs estimated at
RM 250 per ton (UNDP Report, 2008)
Estimated cost of running bio regen machine about RM 130 per ton
Other cost savings – use/sale of fertilizer, health, environmental costs
18

Proposal – pilot project



Purchase a bio-regen machine – cost
RM 18,800
Install in MPPP food court
Assume each machine processes 500 kg per day – divert half ton from landfill

Proposal



MPPP can use fertilizer for landscaping
Encourage hotels, wet markets, hospitals, schools, factories etc to divert waste from landfill
Offer incentives, rebates to institutions that do that.
