Abstract
Purpose
Plastics waste management is a critical agenda for the global community. Recycling is the most important strategy option for recovering plastics wastes. This study aims to review reverse logistics (RL) implementation practices and conceptualizing it to the plastic recycling system.
Design/methodology/approach
The paper is organized after evaluating the studies related to plastics waste recycling and analyzing the available frameworks to use RL as a strategic tool.
Findings
The paper has investigated that previous research on RL implementation focused on a few stages of RL activities and did not include the most important issues. However, for successful RL implementation, taking into account the whole stage and including the most important factors is very important. To elaborate on this finding a new conceptual framework is developed.
Research limitations/implications
The paper is fully based on literature review and international reports. The developed framework is required for further empirical validation in the plastics sector.
Practical implications
The paper has considered the important issues and the applications of those factors that can improve plastics recycling performances.
Social implications
This study can enhance the active involvement of main actors (plastics producers, users, municipal and recyclers) in the plastics recycling system.
Originality/value
This paper deliberates on how RL can be conceptualized and implemented in plastics recycling systems in considering the most important factors for plastics recycling.

Abstract
In 1978 the plastic bottle was introduced nationwide. In the thirteen years since that historic (and some say environmentally devastating) occasion, the consumer increasingly has embraced plastic packaging. Each American uses about 190 pounds of plastic per year, according to Earthworks Group, and about 60 pounds of it is discarded within minutes or seconds after opening. The plastic bottle is king. American consumers use 2.5 million plastic bottles every hour.

Abstract
Recycling has experienced rapid growth as a technique to reduce the solid waste stream volume. Despite the public appeal and acceptance of recycling, the reverse logistics channels used in recycling have received minimal attention. However, the reverse channels′ membership and capabilities have a significant impact on the efficiency of processing recyclable material for remanufacture into recycled products. Differing product characteristics, extensive handling, and low density shipments pose considerable obstacles to establishing an efficient reverse channel for recyclable commodities. A framework, based on interviews and current literature, describes the reverse logistics channel structure, membership and functions, and provides a foundation for identifying the issues affecting efficiency and marketability, and possible future directions for improving efficiency within the reverse channel structure.

Abstract
Purpose
The purpose of this paper is to develop a new model in which the interrelationship between the barriers can be determined that hinder the implementation of effective recycling processes in the plastic sectors of India.
Design/methodology/approach
Today manufacturers do not want their input to be deemed waste and subsequently be discarded, so their efforts and resources have been channeled into the development of efficient recycling methods. However, there are several barriers hindering the implementation of effective and efficient recycling. In this paper several of the most influential barriers are taken into consideration and implemented in the interpretive structural modeling.
Findings
The results divided the barriers into four clusters and identified the weak and strong barriers and implemented relationships between them.
Research limitations/implications
Globally plastic waste has been steadily increasing. Recycling plastic has received much attention because many companies are using it as a strategic tool to serve their customers and to generate good revenue, but there is a lack of effective recycling units in India. The work of this paper and its results will be helpful in the implementation of an effective and efficient recycling unit for the plastic sector.
Practical implications
The recycling process can be improved by avoiding barriers of PLASTIC recycling.
Originality/value
In this paper, the plastic industries of India are studied and analyzed, and the barriers are found.

Abstract
Purpose
The purpose of this paper is to assess the waste characteristics and separation efficiency of source separation of household waste in low- and middle-income communities in Kumasi Metropolis, Ghana.
Design/methodology/approach
A sample of 60 households participated in the household survey, education on source separation and pilot source separation exercise. The solid waste was sorted into six fractions and three recycling categories (biodegradable; paper and plastic; residue).
Findings
The mean generation rate of solid waste was 0.52±0.26 kg/per capita/day for the low-income community and 0.65±0.27 kg/per capita/day for the middle-income community. The waste fractions in the communities (low, middle income) were biodegradable organics (59.15, 65.68 per cent), plastics (11.01, 10.68 per cent), papers (3.15, 4.51 per cent), glass (0.89, 2.57 per cent), metals (0.96, 4.63 per cent) and miscellaneous (24.84, 11.93 per cent), respectively. The separation efficiency for organic category was 70 per cent, inorganic and residue was over 69 per cent and the paper and plastics was over 60 per cent.
Research limitations/implications
The study suggests that the success of source separation programme hinges on education and economic incentives. It was noted that the sample size could be increased to enhance the accuracy of the data for prediction purpose.
Practical implications
The findings showed there is potential for recycling through source separation programme in low-and middle-income communities. Public education and economic incentives are necessary for successful source separation programme.
Originality/value
The paper provides insight into source separation to contribute to better understanding of how city authorities in developing countries could take advantage of economic incentives to scale-up recycling.

Abstract
Purpose
Sustainable end-of-life (Sus-EoL) practices can be achieved through manufacturing of sustainable products, and recovery and recycling after the use phase. To achieve Sus-EoL, the manufacturing organizations should handle their products after their EoL. The recovery of used products is achieved through the design of the collection location. However, the first step is to understand and identify the barriers (e.g. lack of awareness among people, lack of technology, etc.) which prevent the implementation of Sus-EoL practices. The paper aims to discuss these issues.
Design/methodology/approach
This paper is about the 18 barriers responsible for the poor success of Sus-EoL practices of used plastic parts. By applying the DEMATEL method and by incorporating experts’ knowledge, a prominence and causal relationship diagram was developed through which the influential strength among barriers was studied.
Findings
The α value is computed as 0.068, and the values lower than α were eliminated to obtain the digraph. Poor curbside pick is identified as the most dominant barrier in implementation of Sus-EoL practices in plastic parts with an influential score of 3.96.
Research limitations/implications
The research is conducted in the Indian scenario which could be extended to global context by selecting the suitable barriers.
Practical implications
The results from the study can be used by the managers of organizations to enhance the possibility of Sus-EoL practices by incorporating suitable strategies which is the significant contribution of this study.
Originality/value
In the past, few authors discussed about the barriers of Sus-EoL practices; however, the analysis of complex interrelationship does not exist. Thus, the global and group interrelationship has been studied which is expected to pave way for future research in the direction of elimination of barriers and so on.

Abstract
First part of an article which focuses on the use of plastics as packaging material. This use has been increasing at an exponential rate with time over the past decades. After use, most of the plastic waste traditionally has been disposed of into landfills which in turn have led to serious environmental concerns. Landfill sites are decreasing. Discusses options such as recycling and reuse of post consumer plastics which may contribute to solving these environmental problems. Also discusses relevant European legislation.

Abstract
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.

Abstract
Purpose
The problem of plastic wastes is serious nowadays worldwide, although plastic wastes recycling is already in practice. To promote sustainability in plastic waste recycling, the quality of wastes collected should be maintained well, resulted from a good recycling practice. This paper aims to study a new plastic recycling bin (PRB) and poster interventions on the enhancement of university hall residential students’ proenvironmental knowledge, attitudes and intended behaviours (KAB) and actual recycling behaviours; informative and feedback posters were used as interventions.
Design/methodology/approach
This study adopted a quasi-experimental setting to examine the effects of the new PRB on students’ KAB and actual behaviours in recycling, whereas the quality of the recycled plastic was measured according to the extent of cleanliness (CLE), separation (SEP), compression (COM) and sortedness (SOR).
Findings
Results showed that significant positive enhancements in KAB only happened with the use of blended interventions, which included promotion through the PRB and posters, suggesting that the use of the PRB and posters was useful in achieving better recycling behaviour.
Originality/value
Blended intervention study by using new design plastic recycling bin and poster on the effect of students’ proenvironmental and recycling KAB.
