Waste is a by-product of the human existence and evolution. The topic warrants attention given the rapid rate of urbanization and the associated health, environmental and economic impact. Out of the total municipal waste collected, approximately 94% is dumped on land and about 5% is composted. Inappropriate disposal of such huge quantities of waste will have adverse consequences on the health and well-being of the people as well the environment. While this is a matter of global concern, the situation is exacerbated in developing countries which lack the infrastructure to deal with this issue. For example: India is among the top 10 countries in the world generating the highest amount of municipal solid waste. In 2019, India alone generated around 62 million tons of solid waste and this number is expected to increase to 165 million tons by 2030 (Ministry of Environment, 2016).
The proposed framework is targeted at bulk waste generators(BWG)as they contribute to-nearly 30-40% of the daily generated municipal solid waste. For the purpose of explanation, the case of a cooperative housing society has been considered and discussed in the following. This framework is generalized and hence can be applied to hostels, schools, colleges, senior citizen homes, hospitals. A pre-requisite requirement for this is that the BWG should segregate the waste into minimum three fractions: wet (organic/food scraps/peels), dry(packaging) and bio hazardous (sanitary waste) though more waste fractions can help the BWG and the associated civic authority earn more revenue.
This framework has been developed based on fieldwork started in 20151 in the Pune district and in Mumbai. It was prepared after contacting a variety of stakeholders such as ragpickers, consumers, NGOs, civic authorities, policy makers, academics and researchers2 .The main policy guideline used to develop this framework are the Indian Solid Waste Management Rules 20163. Local civic policy guidelines such as subsidies on property tax for under taking eco-friendly initiatives were also considered. This framework involved studying the MSW practices of three large cooperative housing societies4. Two of the societies had been awarded substantial property tax rebates due to a gamut of eco-friendly initiatives while one was modelling itself on the track (followed by the award winners) to qualify for earning financial subsidies in the form of property tax rebates. The process flow chart given below was prepared after observing the initiatives being undertaken by such exemplar BWGs.
Fig 1 shows a model BWG’s MSW pattern. This model has been prepared based on a study of four societies located in the Pimpri Chinchwad municipal corporation (PCMC) limits and after consultation with the above mentioned stakeholders.The PCMC had stopped picking up food waste (or organic component of the MSW) from BWG effective5 2017 timeframe and asked them to compost the foodwaste. Only dry waste (recyclables) and bio-hazardous waste (sanitary napkins and diapers) would be picked up by the civic authority. They have also instituted a system of offering incentives such as subsidies on the property tax for BWG undertaking eco-friendly initiatives.
On the left side of the figure, are five waste fractions. They are food scraps, sewage water (toilet discharge), soiled sanitary napkins, soiled diapers, and packaging waste (can be sold to authorized waste dealers). Food scraps (can be composted) and sewage watercan berecycled on the premises of the BWG by installing a sewage treatment plant (STP) and compost bins. However, the three items namely soiled sanitary napkins, diapers and packaging waste have to be disposed outside the premises of the BWG. Packaging waste (dry waste) has to be given to waste dealers. It is segregated manually by the waste collectors. Sanitary waste is handed over to the civic authorities for disposal. Since this is a model society, it is undertaking recycling/reuse of sewage water (landscaping/gardening). Periodic waste management initiatives as well as socially relevant activities can also be undertaken by the model BWG – such as donation of clothes, used household items, books to an NGO and handing over e-waste and batteries to authorized recyclers. Miscellaneous waste is sent to the landfills.Such socially relevant and eco-friendly initiatives are shown in the middle portion of the flowchart while sustainability initiatives are shown in its right section of figure 1.
In order to propagate such successful case studies, it is important to create a framework which will allow such initiatives to be available in a systematic manner in public domain. This need was echoed by civic officials and NGOs alike. At present the only way that such initiatives are known is via word of mouth (which are local in nature) or through occasional internet articles. The evaluation of eco-friendly initiatives for the purpose of awarding property tax rebates is done manually and the results are not available in public domain for reference. Civic authorities and policy makers want to accelerate the adoption of such sustainable initiatives at BWG points since they are stressed for resources and infrastructure. NGOs feel that the recommendations given in the SWM2016 need to be implemented and an excellent way which can result in a win-win situation is the through the implementation of extended producer responsibility (EPR) guidelines6 The companies (brandowners) are not complying with these guidelines. The exemplar BWGs on the other hand have to fund all of these eco-friendly and socially responsible initiatives through their funds. Property tax rebates received (if at all) offset partial costs a year after they are incurred. All the entities surveyed felt that a reliable data based framework that could help close the existing gaps and help BWGs monetize their initiatives would be very helpful.
This framework aims at combining the synergies of emerging technologies, community participation and policy guidelines to create a reliable data based approach which can : a) propagate the benefits of adopting sustainable waste management practices b) highlight use cases to help facilitate this process c) accelerate the adoption of UN SDGs through an environment friendly and inclusive approach d) create data that can be used in trust less environments e) facilitate the timely availability of data to facilitate governance and reduce the financial and infrastructure pressures on civic bodies through the implementation of EPR. f) enable responsible BWGs to monetize their efforts g) facilitate the transition towards a circular economy approach
There will be a central point (command room or CR) from which this activity will be managed7. A digital map of BWGs adopting the sustainable practices will be created on the SoGReIn website. In addition, a mobile app can be created. Recylables will be geo tagged and sent to a Resource Recovery Centre (RRC). Therethey will besegregated using robotic separation technology and artificial intelligence (AI). While the robotic segregation approach has been used in the developed countries, in case of India this is a recent occurrence. Community participation towards sustainable activities will be encouraged and a digital repository of the same will be created by accepting digital (visual) evidence of the same along with certain data required for verifying the authenticity of the submission. This activity will be done at CR. The brandwise data of the segregated recyclables waste will be used for charging various brands. The funds will be distributed among the civic authorities and the BWGs after deducting some administration and service charges (which will form the revenue for the CR). Blockchain technology will be used to enable data reliability/overcome trust issues8 Moreover greater transparency in evaluating the sustainability initiatives of BWGs will be possible.

In Figure 2 the mechanics of the process are shown. The robotic technology can help to identify the brand-owner and the type of packaging used for the respective product. For sanitary waste the charges can be determined on the basis of the weight9 and be charged to FIHA10.
Data can be obtained from the CR about the revenue earned by the BWG by the implementation of the EPR rules laid down in the MSW 2016 guidelines. This revenue can be shared with the civic authorities (50:50) for using the civic infrastructure and also to cover manpower and administration costs. This will help realize tremendous savings for the civic authorities as nearly 50% of the municipal budget is spent on waste management activities.
Livelihood for waste pickers who can be involved in various aspects of this process: from the point of the origination to the point of disposal. Easily replicable and scalable solution that can help in accomplishing the UN SDG11 3: good health & well- being, SDG 5: gender equality, SDG 6: clean water & sanitation, SDG 9: industry, innovation & infrastructure, SDG 10: reducing inequality, SDG 11:sustainable cities & communities, SDG 12: responsible consumption & production, SDG 13: climate action, SDG 15: life on land.
A data based approach is currently absent due to the lack of awareness of the potential to realize the business case for implementing EPR as well as recovering the resource value embedded in the municipal solid waste.
Data can help citizens monetize their efforts: they can earn through proper disposal of waste; property tax rebates can be another incentive mechanism and sustainability maps can help pioneering BWG attract corporate social responsibility funds. Moreover, based upon the data, community members can negotiate bulk purchase rates and adopt circular economy practices by moving towards a packaging free approach - demanding that this be translated in lower purchase price for them.
Emerging technologies such as AI have the capacity of storing thousands of images plus process the waste in an expeditious manner. Although some upfront investment will be required for setting up the systems and the software, EPR recoveries will be able to overcome the initial investments. Involvement of research institutes in developing the technology infrastructure will not only help to bring down the development costs but also generate scientific literature. Smart contracts help in automated recoveries from brand owners thereby reducing the transaction/funds processing times.
The digital map which is a part of the SoGReIn framework can be used to display the case studies of exemplar societies. A sample of the questionnaire is given below in Fig 4. This questionnaire will be used to collect data from BWGs. BWGs will be required to submit digital/photo evidence to substantiate the claims. Independent verification of the visual evidence and the data submitted will be conducted through independent volunteers.The services of such volunteers will be sought via the website/app which will host the SoGReIn framework.
