ROUND COLLECTED REFUSE (RCR)
Definition Characteristics Risks – Health and physical Physical handling of the waste
Bags Wheelie Bins Other containers
Recyclable content
TRANSPORT OF ROUND COLLECTED REFUSE (RCR) Open top trucks and trailers
Caged trucks
Compactor trucks
BENEFITS OF COMPACTING WASTE Allows waste containers to be emptied into the vehicle
from the rear, the front, or the side, and vehicles can be fitted with bin lifters;
Compacts the waste to a high density using hydraulic or mechanical pressure;
Removes the waste from view quickly; and Inhibits vectors and insects from reaching the waste
during collection and transport. Compactor trucks work well where:
there are paved streets wide enough to allow passage and turning;
the waste is set out in containers or bags, so that crews can pick them up quickly; and
the density and moisture content of the waste are low. generation of dual, or divided, compacting vehicles
WHEN WILL CAGED VEHICLES BE USED?Advantages of non-compactor trucks Non-compactor trucks are a sound technical
practice for solid waste collection under the following conditions:
The waste is generally very wet or dense; Labour is relatively inexpensive, compared to
capital; There is limited access to highly skilled
maintenance; Collection routes are long and relatively
sparsely populated, and Downtime for maintenance must be minimized.
ENVIRONMENTAL COST OF SOLUTION SELECTION
Fuel saving (fossil fuel!) Carbon footprint Pollution from NOx, Sox, CO2 and CO Risk of refuse scatter Risk of vector propagation Visual acceptance Contribution to traffic congestion and
road safety
COST BENEFIT ANALYSIS Travelling time Staff costs Vehicle cost Maintenance cost Vehicle availability Number of vehicles Environmental cost such as carbon
emissions Management cost
IMPORTANCE OF GOOD DATA COLLECTION AND ANALYSIS
Information is King! You cannot manage what you do not know. Data collected but not analysed is useless! Act on the outcomes of the data collected and
analysed. What data should be collected:
All costs, fixed and variable (Capital, operational and maintenance)
Waste densities Weight per load Distances travelled Performance
IMPORTANCE OF DRIVER AND STAFF TRAININGWhy?
Equipment is expensive and must be handled by properly trained drivers and operators
Safety of staff Environmental risks Improved performance Cost efficiency
Outcome: Productive staff who enjoy their work Cost effective service.
