6. Planningadvice: Recommendationsforcontainersettings Main guidingprinciples: • Capacitiesshouldsufficethe needs of the citizens to get rid of their generated waste within reasonable (sanitary and space constraints) intervals, i.e. nobody should be forced to litter or dump waste in nature • Container distribution should allow convenient disposal (acceptable distance from the source of waste generation) • Container distributionandcapacitiesshouldallowcollectiontourstobeasmuchefficientaspossible

12. Planningadvice: Recommendationsforcontainersettings Container provision (approximation) • Container capacitiesforhouseholdcollection • mostcommon (MGB) 120 / 240 / 360 / 770 /1100 litres • Limitingfactor • volumeusable (=net) volumeisdeterminedbybulkdensitybulkdensitynormallyrangesbetween100-200 kg/m³ example: 120 l, 150 kg/m³ Bulkdensity = 18 kg per container 1100 l, 100 kg/m³ Bulkdensity = 110 kg per containeroneperson in projectregiongeneratesabout 0.7 kg ofwaste per day i.e. wastefromabout 150 personswouldfillthecontainerwithin 24 h

13. Collection: Somekeyfigures Container collection (fromhouseholds) • Container grossweight Bulkdensity = pouringdensity * fillinglevel • Limitingfactors • working time • human power (laborprotection, OHS provisions)example: 120 l, 150 kg/m³ Bulkdensity = 18 kg per container, for 900 container per shift = 16 t !!

14. Planningadvice: Recommendationsforcollectionlogistics Routing guidelines (also mentioned in ANNEX 1 of TR MWC) • Routes should not be fragmented or overlapping. Each route should be compact consisting of road segments clustered in the same geographical area. • Collection plus haul time should be reasonably constant for each route. • The collection routes should begin as near the garage or truck point of origin as possible. • Within the route, right hand turns are preferred to left-hand turns because of their greater efficiency. Collecting from one side of the road at the time, it is generally best to route with clockwise right turns around blocks • Heavily travel roads should not be collected during rush hours. • One-way roads are best collected by starting near the upper end of a road working down through a looping process. • Dead-end roadways should be considered as a segment of the roads they intersect. They must be collected by driving down and making a u-turn. • Steep hills should be collected on both sides of the road while the truck is moving downhill for safety, loading ease, collection speed, vehicle wear, and fuel conservation. • Higher elevations should be at the start of a route.
