This study aims to investigate the adoption of waste-to-energy (WtE) technologies in South Africa (SA), focusing on identifying the key drivers, barriers and potential solutions for commercial uptake. The ultimate aim is to propose an implementation framework that promotes renewable energy while reducing landfill reliance.

A systematic literature review (SLR) of papers published between 2020 and 2023 was conducted to identify factors impacting WtE adoption in SA. The conceptual model developed from the SLR was tested using a qualitative case study approach. Data was collected through 15 semi-structured interviews with commercial entities and WtE experts from four regions of SA.

Anaerobic digestion and pyrolysis are identified as the most suitable waste-to-energy technologies in the South African context. Among the financial challenges of WtE in SA, the availability of cheap coal, low landfill tariffs, high capital costs, funding constraints and regressive economic incentives are critical. The lack of government support, insufficient incentives, regulatory burdens, weak policies and limited innovation capacity are considerable non-financial barriers hindering WtE technologies’ growth. The successful adoption of renewable energy also requires adequate infrastructure, increased sustainability awareness and technical expertise.

Although the sample size is diverse and consists of a range of organisations, it may not capture the thoughts and experiences of other SA businesses in their entirety. It is important to note that the lack of existing research on the implementation, benefits and impacts of WtE technologies limits the authors’ ability to interpret and benchmark the findings of this study. Yet, this study contributes by developing an implementation framework to encourage WtE adoption, recommending policy actions such as regressive taxation on fossil fuels and landfills and promoting renewable energy through subsidies, awareness and energy credits.

This study provides a practical framework for businesses and policymakers to adopt WtE technologies by addressing key barriers. The research suggests that businesses could reduce waste management costs and generate new revenue streams by adopting anaerobic digestion and pyrolysis. Policymakers are encouraged to disincentivize landfills and promote WtE through financial incentives such as subsidies and energy credits. The implementation framework offers clear recommendations for integrating WtE into SA’s energy and waste management strategies, supporting both sustainability and economic goals.

The main social contribution is the potential for WtE adoption to improve waste management practices and generate new job opportunities within the renewable energy and waste sectors.

This study provides a novel contribution by developing an implementation framework tailored to SA’s unique regulatory, economic and social contexts. The research highlights the importance of aligning WtE adoption with sustainability goals, reducing reliance on fossil fuels and promoting renewable energy. The framework serves as a practical guide for policymakers, businesses and industry leaders seeking to implement sustainable waste management solutions in SA.

This study investigates the role of leadership and cultural transformation in facilitating Lean Six Sigma (LSS) practices in clinical pharmacy settings to reduce medicine waste within the UK National Health Services (NHS).

A systematic literature review on Lean Six Sigma in health care was conducted to develop an analytical framework. This was followed by a qualitative case study of an English NHS trust to test the framework, exploring pharmacists' adoption of LSS practices and their impact on staff behaviour, focussing on leadership decisions and organisational culture.

The research highlights the significance of leadership’s prioritisation in waste reduction efforts and its influence on staff engagement. It also examines the intricate relationship between leadership decisions, education and training, resource allocation, and the prevailing clinical culture, which shapes pharmacists' behaviours and attitudes towards LSS practices and waste reduction.

The study’s focus on a single NHS trust limits the generalisability of the findings, suggesting the need for further research across different healthcare settings.

The study recommends a cultural transformation, earlier training, and reformation in service strategy to enhance the adoption of LSS practices and contribute to a more sustainable future for the wider health services.

Effective medicine waste management prevents harm and helps address the current NHS medicine shortage. The NHS can allocate resources efficiently, ensure timely treatment, and prepare for future disruptions by implementing the proposed framework.

We developed a leadership model for the NHS to reduce medicine waste, offering a novel approach to addressing the challenge of medicine waste through leadership and cultural transformation.

There is a critical gap in assessing how institutional voids affect SMEs' growth, investment commitment and reputation. The purpose of this paper is to explain how institutional void affects these three dimensions of SME performance; and to develop an institutional void-SME performance framework that can be applied for strategising, resourcing and competency acquisition for better performance.

The study used the Enterprise Survey Data of the World Bank, consisting of 118,763 firms from 140 countries. The structural equation modelling (SEM) is used to analyse the data, validate our analytical model and investigate the imposed theoretical claims of causality as indicated by specific research questions through correlation/covariation between the constructs of institutional void and SME performance.

Evidence suggests that there is a strong positive correlation between formal institutional infrastructure (independent variable) and SMEs' reputation (dependent variable). Among the institutional sub-constructs, tax administration, business licensing and permits, access to a bigger market and skilled labour and informal competition are significant for the SME performance constructs. We find similar results while comparing SMEs with large businesses.

The institutional void-SME performance framework developed from our findings will allow SMEs to manage institutional voids affecting their performance. The analytical framework can also be the foundation for future empirical research.

The originality of the study is embedded in its investigation of SMEs' investment commitment and reputation in relation to institutional voids. The latent relationship between the sub-constructs of institutional voids and SME performance adds new knowledge to the dynamic relationship between institutions and firm performance.
