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
