The local economy of a community is equally supported by the formal sector, but also by the informal sector. While the formal economic activities are carried out through modern, technical, industrialized means, within public or private organizations whose existence is officially recognized and benefiting from the protection of the authorities, the informal activities exist outside the official control and protection system.

There is a dynamic connection between the actors in the formal sector and those in the informal sector, which is seen at the levels of production, distribution and consumption of goods and services.

This article analyzes the waste recycling informal activities carried out by persons or enterprises involved in the extraction of recyclable materials from generated waste and evaluate the informal waste sector perspectives and implications from three points of view: economic, social and environmental views. At first sight, the informal waste collection and recycling is neither efficient, nor viable, the social, economic and environmental benefits resulted from waste valorization possibilities are clearly superior in the informal waste sector compared with formal waste activities.

Community waste management: Iyer , in his well known literature available to understand waste management and efforts to involve local communities in the system of waste segregation talks about how the Mumbai Metropolitan Region MMR , spread over 4,sq. All Municipal Corporations in India are mandated to look into solid waste management in their functional domains under the 74th Constitutional Amendment.

At present, all the seven municipal corporations depend upon centralized means of managing waste which is dumped at assigned landfills post collection. Apart from the corporation, there are multiple players who play a crucial role in managing this waste. Much of this is managed by the informal sector and now emerging recyclers who are setting up processes for decentralized waste management.

More importantly, it is imperative to understand the failure and limitations of the municipal corporation since they are financially dependent on the centre and state for their functioning. But despite all those constraints, it makes sense to gauge energy and material recovery potentials and correlate to municipal waste management. By means of different examples and a technology provider for bio-medical waste, we are able to make an impact towards creating greener, sustainable communities. Waste is the epitomized result of major ongoing negative human impacts and the current economic paradigm based on unlimited growth.

An increasing number of scientists now believe that humanity has driven the world into a new geological epoch. Production, consumption, and waste disposal are at the heart of these transforming forces that are changing the planet in countless, problematic ways.

Zero waste requires transforming infrastructures and policies, but also education, training, and ongoing research. Above all, more than technological solutions, it requires a society-wide shift in governance, values, norms, and behavior. In fact, some of the most innovative ideas and solutions for eliminating waste can be found, not in wealthy industrialized countries, but in the Global South. These cases demonstrate how processes such as conscientization and community-based initiatives can be effective in practice.

It looks at two local level initiatives formed to create a sustainable solid waste management system. However, tasks such as solid waste management cannot be left to local level initiatives as community organisations lack sufficient resources or capacity to provide such a service in its entirety. Policy-makers need to give such areas more civic autonomy or provide, via the state government, a modicum of basic environmental services. Through the study of the urban local body, a private agency and a civil society organization engaged in this activity, the paper highlights issues related to effectiveness and equity, role of the urban poor in this service, and the relevance of an effective policy framework.

In the context of increasing private sector participation in public service provision, and global awareness related to the impact of urban footprints on the planet, the study brings out some interesting lessons on the nature of public-private partnerships in SWM, and the role of the state in guaranteeing social and ecological equity and accountability. It also points to the urgent need for a change in the way the state itself approaches solid waste management, stressing policy mandates that will enforce equitable and ecologically sustainable waste management practices across the country.

The study is based on qualitative research methodology, and involved in-depth interactions and discussions with residents, agency officials and conservancy workers, detailed examinations of secondary literature on SWM systems, and intensive field observation of SWM processes in the three agencies in Chennai. Thanks for sharing your informative synopsis of waste management literature available, and for spreading awareness about this ever-present challenge.

Waste management is one of the most challenging assignment in our part of the developing countries. Its good to read through this your informative post. Thanks and sharing! This is a very timely and important topic to be discussed. Continuous power-quality monitoring uses advanced sensing technology to analyze and interpret raw measurement data to improve systemwide power-quality delivery.

This ensures that urban infrastructure systems requiring a consistent supply of high-voltage power, such as an electrified light rail, suffer less damage such as from overheating and component failures during their useful lifespan. In city environments, every square meter costs.

In an effort to support the dietary needs of the often colossal populations that inhabit their limited spaces, urban farmers use unconventional infrastructure such as skyscrapers and rooftops to harvest crops in and atop vertical farms. To effectively grow within such structures — which can be significantly less accessible than the conventional rural landscapes where most traditional farms exist — such farmers need real-time access to vital agricultural parameters such as evapotranspiration rates, soil moisture saturation and groundwater conditions.

  4. Measuring air quality and weather conditions is increasingly important for those involved in the construction of new infrastructure. Whether building residential units, roads, bridges or any other piece of infrastructure, activities such as land clearing, running diesel engines, demolitions and burning can all adversely impact air quality, placing the health of the general population particularly those with respiratory diseases at risk. Assessing atmospheric conditions, such as wind speed and direction, is also important to predict the risk of such pollution spreading to adjoining territories.

    Research has demonstrated that asthmatics are 40 percent more likely to suffer acute asthma attacks on high pollution days than on days with good air quality. Smart sensors and special IoT communication networks are the two key components of any smart city project. Sivan Cohen, P. Broadband provides students in rural and underserved urban schools access to online resources that can help them better prepare for the workforce.

    Telematics can optimize smart transportation. Access to aggregate data allows cities to closely monitor traffic flows, understand the effects of new projects and speed reduction programs, assess the efficiency of traffic signals, map air quality and highlight hazardous intersections. All these tools help cities and municipalities better manage the overall transportation system.
