Key challenges to wasteKey challenges to wasteminimisationminimisation

Legislation & other legal barriers which can delayproactive alternative solutions e.g. the necessary EIA,Permitting procedures and land use planning issues

Funding & capital expenditure for Private and Public

sectors Municipal Finance Management Act & other

Procurement processes

Customers are generally driven by the price of the

service and not necessarily interested in alternativesolutions (especially relevant for the private industry)

Time constraints as the roads are becoming morecongested which leads to transport delays

Key challenges to wasteKey challenges to wasteminimisationminimisation

Lack of skilled people in the industry private, public (including regulating

authorities)

Lack of inter-departmental and inter-governmental communication

Creating markets for recyclables to ensure a

sustainable recycling economy Participation mostly voluntary

Gaps in information


13/17

OpportunitiesOpportunities

Partnerships Business re-engineering including the

establishment of new business and changing

business as unusual Extended ProducerResponsibility

New markets promotion of alternative

treatment methods to open up the recyclingeconomy

Decrease in reliance on raw materials if

recycling initiatives are increased


14/17

OpportunitiesOpportunities

Increased public awareness (changingbehaviour) as to their role in wasteminimization and rec clin

Increased landfill airspace savings

Implementing instruments

Green Procurement Policies

Current & future plansCurrent & future plans Current:

2-bag think twice project Building rubble crushing

Green waste chipping composting, mulch

Sewage Sludge composting/land application Future:

Roll out of 2 bag / yellow bag system ?
