Collection of segregated municipal waste is an essential step in MSWM. Inefficient waste collection services have an impact
on public health and aesthetics of towns and cities. Collection of wet, dry and domestic hazardous waste separately ensures
maximum recovery of recyclables. It also enhances the potential of cost-effective treatment of such wastes which can then
easily meet the minimum quality criteria defined for different products, eg. production of compost from pure organic waste.
Waste collection services are divided into primary and secondary collection. Primary collection refers to the process of
collecting, lifting and removal of segregated solid waste from source of its generation including households, shops, offices,
markets, hotels, institutions and other residential or non-residential premises and taking the waste to a storage depot or
transfer station or directly to the disposal site, depending on the size of the city and the waste management system prevalent
in the city. Primary collection must ensure separate collection of certain waste streams or fractions depending on the
separation and reuse system applied by the respective town or city
Secondary collection includes picking up waste from community bins, waste storage depots, or transfer stations and
transporting it to waste processing sites or to the final disposal site
Solid Waste Collection

Primary collection of segregated MSW from individual households and establishments (door-to-door collection) is accomplished
through the use of containerised pushcarts, tricycles or small mechanised vehicles, compactors, or tipping vehicles depending on
the terrain of the locality, width of streets, and building density.
Spacious and well-lit safe neighbourhoods allow collection systems with compactor vehicles and tipping equipment which are
more efficient. Narrow streets do not allow for the use of conventional primary collection vehicles. In cramped neighbourhoods,
handcarts or pushcarts, or tricycles or small mechanised vehicles may be used for door-to-door collection of waste, which may
then be transferred to a larger vehicle in the vicinity. Where access to individual houses or establishments is difficult, handcarts
or rickshaws could be made to stand at designated spots.
PRIMARY COLLECTION

5. RV College of
Engineering Go, Change the World
In hilly areas, many of the houses are accessible only by footpaths or steps, thus restricting the use of handcarts and tricycles.
Segregated waste from households in hilly areas should be collected using backpacks having small leakproof containers up to
50l capacity or using local traditional load-bearing methods like pack animals, shoulder poles, headbands, wheeler bags, etc.
The waste collectors should ideally collect wet waste from each household with a bag or basket on their back and with
another bag for dry waste. The waste collectors should be well equipped with personal protective equipment (PPE) and
should also be provided with a whistle to announce their arrival for waste collection.

Vehicles and equipment for primary collection
Primary collection vehicles should meet local requirements. Before selecting a vehicle for primary collection, it is advisable
to assess the amount of waste generated, local climatic conditions, topography of the area, and available facilities for repair
and maintenance of vehicles.

Handcarts or Tricycles with Containers or Bins
• Handcarts should have a capacity to carry 4 to 6 containers of 40 to 60l capacity. The containers should be green for wet
waste and blue for dry waste . Bins should be made of HDPE, injection or roto molded, UV tested, and universally used as
standard garbage handling bins.

• Containerised handcarts are suitable for door-to-door collection of MSW from households, shops, and establishments from
narrow lanes and hilly areas and also for collection of street sweepings where women sanitation workers are involved. Bins or
containers can be easily unloaded into secondary collection bins or secondary transport vehicles based on the prevalent
collection and transportation system in the ULB. This can be done without depositing the waste on the ground, avoiding multiple
handling of waste.
•Tricycles with 6 to 8 containers of 40 to 60 l capacity can also be used for door-to-door collection of waste from narrow lanes.
Male workforce is engaged to facilitate the picking up of larger quantity of waste in one trip and taking the waste to a secondary
waste storage depot placed at a longer distance.

Hand scrapers, shovels, brooms, washers
Common waste collection chores include washing, disinfecting, and cleaning in corners, surfaces beneath fences,
along partitions, in alleys, and in stalls or pens.
Shovels, forks, scrapers, brooms, brushes, pressurewashers, and related hand tools are needed for small area
cleanup.
Long, upright-handle brooms are used to sweep corners and small spaces, even wet areas. Push brooms that are
up to 2.5 feet wide assist fast cleanup of large areas.

Tricycle with hydraulic tipping containers
MSW tricycles should have mild steel epoxy painted and tipping containers of 350l (140 kg per trip). The tipping containers
should be mounted on a standard tricycle . These tricycles are suitable for door-to-door collection from small lanes and
small waste generators.

Light Commercial Vehicles (Mini Trucks) with Hydraulic Tipping Containers
These vehicles are suitable for door-to-door collection of segregated waste for lanes with less than 5m width. They have a total
payload capacity of nearly 600–900 kg per trip. The load height is approximately 1,500 mm from the ground level. They should
have a leakproof MS load body with drainage tube and plug. The small tipper should be built on a suitable chassis. These
vehicles should have four openings, two on each side to facilitate direct transfer of waste from a domestic bin to the vehicle.
They can also have a central removable partition to facilitate storage of segregated waste. It is desirable to use up to 3m3
capacity vehicle for door-to-door collection to cater to a large number of houses in a single trip.

Four-wheeled Mini Trucks with International Standard Bins
Normally the practice is to unload the small containers manually into the bin or the hydraulic container. The main advantage of the
four wheeled mini truck using bins instead of a hydraulic container is that the loading height can be decreased from 1,500mm to
1,200mm or less from bins placed on the ground. For the same logic, this type of system cannot be fitted on the larger chassis
because then the loading height would be even higher. Avoidance of hydraulic tipping will make these trucks suitable in remote
places, where provisions for maintenance of the hydraulic component of a large number of vehicles may not be available. Further,
maintenance is costly and time-consuming. A typical setup is that the vehicle can carry 8 bins of minimum 240 l. Bins should be
made of injection or roto molded HDPE. Each mini truck should carry 4 green containers for wet waste and 4 blue containers for
dry waste.
ULBs should have adequate workshop facilities for the maintenance not only of their fleet of vehicles, but also of containers,
handcarts, etc. The workshop, public or private sector, or public–private partnership (PPP) should have adequate technical staff
(trained men and women), spares, and preventive maintenance schedules to ensure that at least 80% of the vehicles run on the
road each day and the downtime is minimised to the extent possible.
