Currently, Mauritius is adopting landfilling as the main waste management method, which makes the waste sector the second biggest emitter of greenhouse gas (GHG) in the country. This presents a challenge for the island to attain its commitments to reduce its GHG emissions to 30% by 2030 to cater for SDG 13 (Climate Action). Moreover, issues like eyesores caused by littering and overflowing of bins and low recycling rates due to low levels of waste segregation are adding to the obstacles for Mauritius to attain other SDGs like SDG 11 (Make Cities & Human Settlements Inclusive, Safe, Resilient & Sustainable) and SDG 12 (Guarantee Sustainable Consumption & Production Patterns). Therefore, together with an optimisation of waste collection, transportation and sorting processes, it is important to establish a solid waste characterisation to determine more sustainable waste management options for Mauritius to divert waste from the landfill. However, traditional waste characterisation is time consuming and costly. Thus, this chapter consists of looking at the feasibility of adopting machine learning to forecast the solid waste characteristics and to improve the solid waste management processes as per the concept of smart waste management for the island of Mauritius in line with reducing the current challenges being faced to attain SDGs 11, 12 and 13.

The chapter aims to evaluate the efficacy of stakeholder participation in the solid waste management system of Mauritius in view of providing a possible mechanism to attain the goals of a sustainable waste management framework.

The study employs qualitative indicators, namely, User Inclusivity and Producer Inclusivity of the Wasteaware Benchmark Indicators. Secondary data are used to conduct a critical and comprehensive analysis of the sub-indicators falling under each of the two main indicators to determine the overall compliance level with respect to stakeholder engagement of the waste management sector of Mauritius.

The results of the study show a LOW/MEDIUM compliance level for both User Inclusivity and Provider Inclusivity indicators, which indicates that improvement is required in the stakeholder engagement mechanism in Mauritius. The main weaknesses identified comprise of lack of an adequate legal framework with clear definition of waste types with regards to segregation, especially for non-hazardous wastes, low efficiency of sustainable waste management awareness campaigns and lack of inclusion of the informal sector. The main strengths identified consist of a proper bidding mechanism in place and a good level of equity in the provision of waste management services with respect to comingled waste collection. Suggested improvement areas include a revamping of the existing legal framework related to waste management to cater for higher inclusivity of all stakeholders together with including sustainable waste management topics in the formal education curriculum.

The User Inclusivity and Producer Inclusivity indicators were previously applied only to cities to measure the level of stakeholder participation, but this study has demonstrated that these indicators can also be adopted on a nation-wide level to evaluate stakeholder engagement. The use of these indicators together with secondary data presents a less time-consuming method to assess stakeholder participation in the waste sector, which can be particularly useful for Small Island Developing States.

Sustainable recycling activities in higher education institutions (HEIs) are crucial as it serves as a common benchmark to a community that is socially and environmentally responsible. This chapter presents a suitable case study of HEIs in Malaysia reporting on recycling rate, monitoring the recycling patterns, and matching the significant recycling policy in the HEIs. Therefore, four HEIs including Universiti Teknologi Malaysia (UTM), Universiti Malaya (UM), Universiti Kebangsaan Malaysia (UKM) and Universiti Putra Malaysia (UPM) were selected as the suitable case studies to examine the practices of recycling activities. These four HEIs are Malaysian research universities that are ranked in the top 300 in the UI Green Metric World University Rankings. Several findings and previous works were reviewed; further steps to set a recycling target were identified and served as a guidance of the standard recycling rate. Results showed the selected HEIs reflected the low percentage of recycling rate in the range of 0.03–29.26%, depending on its practices and policy. Three phases of planning have been structured to target the recycling rate at HEIs in Malaysia with the First Plan (2025), Second Plan (2035) and Third Plan (2040) towards the recycling rates of 20%, 30% and 40%, respectively. The recommendations for the HEIs formulate recycling policies and recycling rates, and for waste management, academia and research centres to play a more active role in increasing the efficiency of recycling activities for a positive impact on the recycling rate in HEIs.

India generates a massive 9.4 million tonnes of plastic waste annually; out of which approximately 5.6 million tonnes go for recycling and 3.8 million tonnes are left uncollected or leaked from after-use collection systems. Reckless production and consumption of non-biodegradable plastic has serious implications, especially for developing nations where plastic use is predominant for fulfilling needs of increasing population and rapid urbanisation. Despite the harmful impacts of plastic, its desirability is inevitable due to its versatility. For the stringently growing economies, affordable and durable solutions will always be priorities over mindfulness. Imprudent plastic waste has precipitated the ban-change-collect challenge. Options like banning single use plastic (SUP), using alternative bio-benign products and improving waste collection systems are not proactively embraced by businesses and governments. Also, user-awareness and behaviour change for make-use-dispose is not instantaneous and easy. Optimistically, the government, NGOs and industry units have started exhibiting sensitivity to the cause and the emergence of start-ups is decentralising waste management in India. Inclusion of informal waste pickers in the formal waste management system has increased the reach and social impact of start-ups in India, imparting a distinctive and promising twist to the waste management sector. This chapter investigates the plastic waste management scenario in India through extensive literature review. It scrutinises the social aspects associated with the plastic waste management sector and attempts to comprehend connotations of ‘socially responsible plastic’ through semi-structured interviews with service providers in the sector. Thematic analysis was used to analyse interview data. The research indicated the initiation of systemic efforts towards formalisation of the sector. It emphasised the importance of role of waste pickers and their recognition as enablers of the system. Need of an ecosystem approach to nurture start-ups and facilitate better transparency and integration in the waste management system is also illustrated in this research.

This paper examines the current tendencies associated with transnational mining capital in the context of the current period of neoliberal globalization dominated by transnational corporations, and examines the usefulness of the category accumulation by dispossession, Harvey’s adapted version of Marx’s original accumulation. After a review of the original concept by Marx an evaluation of Harvey’s concept is presented. The current state of affairs in the mining industry is examined, in particular, considering the present level of large scale mining or mega-mining. In addition, this paper examines the associated social conflicts addressing the social and environmental impacts, which have resulted from these recent tendencies, not to mention the problems of increased use of corporate management of social resistance, and repression, on the part of the State, especially with regards to the criminalization of social protest. Moreover, the tendency toward reprimarization in several countries is considered and the degree to which this coincides with ongoing expropriation by the State is addressed, followed by an assessment of the relevance of the concept of accumulation by dispossession in the present day.

The post-Cold War period allowed the U.S. nuclear legacy of ecocide to be declassified and made public. The policy of nuclear secrecy, evident in Russia (see Mironova et al., this volume), was not merely an eastern practice. Western nuclear releases were kept equally under wraps. In England, for example, the Windscale disaster was not fully disclosed until 1987.¹ Likewise, releases from the Hanford Nuclear Reservation, in Washington State, and other U.S. nuclear sites were kept undercover until the same period. The irony was that Americans learned of many of the nuclear skeletons in their closet around the time that Russians learned of theirs (see Mironova et al., this volume). It would appear that glasnost was contagious.

Every year, tens of millions of the 1.4 billion cars on the world’s roads are decommissioned. While the ferrous and other metals that constitute about 75% of a vehicle by weight can be readily and profitably recycled, the remaining mix of plastics, glass, composites, complex materials, fragments and contaminants are mainly destined for landfill as automotive shredder residue (ASR). For every car, approximately 100–200 kg of ASR is disposed of in landfill, posing a growing technical and environmental challenge worldwide. The recovery of the ASR for high-end application is the focus of this study, aiming to optimise the use of these valuable resources and minimise the extractive pressure for raw materials, a future green manufacturing, contributing towards a zero waste circular economy. As the dissolution of carbon into iron is a key step in the manufacture of iron-carbon alloys, the feasibility of utilizing the waste polymers within ASR as sources of carbon in different areas of pyrometallurgical processing was investigated. Polypropylene and rubber, in a blend with metallurgical coke, were used as carbonaceous substrates and the slag-foaming phenomenon was investigated via the sessile drop technique in an argon environment at 1,550°C. The results indicated the rubber/coke blend achieved significantly better foaming behaviour, and the PP/coke blend exhibited a moderate improvement in slag foaming, in comparison to 100% metallurgical coke. The overall results indicated the incorporation of ASR had significant improvement in foaminess behaviour, increasing furnace efficiency.

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.
