DRY WASTE COLLECTION CENTRES
Context: The Bruhat Bengaluru Mahanagara Palike (BBMP) is looking to rebuild, renovate and upgrade its dry waste collection centres (DWCCs) in the city.
- This decision was taken following an audit of all the 143 DWCCs in Bengaluru,
- People working in these centres had raised several issues about their work conditions such as poor lighting and ventilation, lack of proper plumbing and sanitary connections, structurally unsound buildings, and mainly, space constraints.
HASIRU DALA STUDY
- Hasiru Dala, an organisation that works towards bringing rag pickers into the mainstream, had conducted a study of 16 DWCCs taking into consideration capacity, working conditions, type of waste received, and operational necessities, such as flow of waste through the centres.
- Some of the suggestions included installation of CCTV cameras, a garden or space for flowering plants such as jasmine, tube rose, and champa to keep foul smell in check.
- Rainwater harvesting, solar lights, pest control measures, a small composting unit for wet waste that comes in with the dry waste, storage drum for dry leaves, and proper sanitary bins were also the requirements the study had highlighted.
The BBMPs new design is largely based on green building concepts (rainwater harvesting, solar lighting, natural lighting, and ventilation) with separate areas and zones for receiving mixed dry waste, sorting, and storing for seamless flow or activities, and visual cleanliness.
Some of the key amenities, such as fire sprinkler systems, toilets, changing rooms, office, and lunch areas for the workers, have been included.
DRY WASTE COLLECTION CENTRES
Dry Waste Collection Centres (DWCCs) facilitate the stream lining of the entire process of waste management, by concentrating exclusively on dry waste.
They are equipped with appropriate infrastructure capable of purchasing, collecting, aggregating and processing both high value and low value dry waste such as plastics, paper, glass, tetra packs, etc.
The city has 189 Dry waste collection Centres.
