AbstractPrecious metal recovery from electronic waste, termed urban mining, is important for a circular economy. Present methods for urban mining, mainly smelting and leaching, suffer from lengthy purification processes and negative environmental impacts. Here, a solvent-free and sustainable process by flash Joule heating is disclosed to recover precious metals and remove hazardous heavy metals in electronic waste within one second. The sample temperature ramps to ~3400 K in milliseconds by the ultrafast electrical thermal process. Such a high temperature enables the evaporative separation of precious metals from the supporting matrices, with the recovery yields >80% for Rh, Pd, Ag, and >60% for Au. The heavy metals in electronic waste, some of which are highly toxic including Cr, As, Cd, Hg, and Pb, are also removed, leaving a final waste with minimal metal content, acceptable even for agriculture soil levels. Urban mining by flash Joule heating would be 80× to 500× less energy consumptive than using traditional smelting furnaces for metal-component recovery and more environmentally friendly.

Strong Ground

In recent years, the need of every corporation to address the environmental issues has grown multifold. The corporate social responsibility concerns are growing, and it has become an indicator to judge a business performance. In the context of increasing environmental concerns where issues of pollution, generation of wastes, use of toxic substances for packaging, etc. are gaining strong ground, the consumers have also become alarmed and they fully understand the implications of such issues both on nature and earth. The chapter aims to study the behaviour and the change therein of Indian consumers. It is true that all the efforts and policies targeted towards initiative of green marketing cannot be realised if it is not received by the consumers. The chapter proposes to cover the concept of green marketing and its relation to the circular economy, the green marketing practices in Indian context, the attitude and preference of the Indian consumer towards green products, and the switch in the purchase pattern of the Indian consumers with respect to green/recycled products.

The future of waste is electronics. The conditions of planned obsolescence combined with our throw away culture of capitalistic consumption has created the largest and fastest growing waste stream responsible for spatially transforming environments. Through the process of reclaiming precious materials contained within our dysfunctional electronics, urban mining becomes a form of resistance to the economics of consumption by recognizing electronic waste as a resource and turning its perceived detritus into value. If waste is central in the processes of capitalist urbanization, can architecture improve the condition of configuring industrial form to create ecology between e-waste, culture, and urbanity? Are there opportunities for e-waste and its architecture to have a public value and legibility in the city? Within this space of speculation, this thesis will explore the untapped architectural possibilities associated with the management of electronic waste and the production of space.

E-waste coming out from the electronic sector of the entire world is harming the world's environment. There has been a pattern of a substantial increase in the production of E-waste worldwide. This is as a consequence of population increase, industrialization, urbanization and economic activity. Since the last decade, the rate of consumerism has been found to be very high due to higher economic growth, which has resulted in increased E-waste production. Almost all countries are recycling more and more E-waste, but a million tonnes of E-waste still coming out. Experts believe that the rise of E-waste is due to our rapidly changing lifestyles. We have started adopting new electronic devices coming into the market, trying to make life more convenient. In  India, electronic waste is growing at 10% per annum.  The trend of urbanization has played a significant role in the enhancement of E-waste generation. The population living in urban areas was 27.67% in 2000, 38.03% in 2018, and is expected to reach approximately 42% in 2025. As the population increases, the amount of E-waste will also rise to an alarming situation. This review paper provides the present scenario of E-waste and its management practices and legislation in the present Indian context. This would help all the stakeholders involved in the production of electrical equipment to gain better understanding of E-waste.
