Abstract

The plastics recycling industry plays a vital role in reducing the environmental impact of plastic waste. However, challenges such as high operating costs and low profit margins are hindering its growth. This article explores the application of lean production systems as a potential solution to improve operational efficiency and profitability in this industry. By reducing waste at various stages of production, such as energy consumption, raw materials and production time, lean has been shown to reduce operating costs by up to 10% in large-scale production. In addition, Lean enables companies to increase production capacity without significantly increasing costs. Despite the challenges associated with initial investment and organisational culture change, the long-term benefits of implementing Lean, such as increased profit margins and competitiveness, make it a highly relevant strategy for the plastics recycling industry.

Abstract

The integration of digital innovation in the plastic recycling industry has become a strategic step to enhance efficiency, transparency, and competitiveness amid complex waste management challenges. This study employs a literature review approach to examine the potential implementation of digital technologies, including cloud-based financial systems, real-time logistics tracking, and e-wallet applications, to support financial management and distribution processes in the recycling sector. The findings indicate that digitalization has the potential to reduce operational costs by up to 25%, expedite financial reporting, and enhance investor confidence. Nevertheless, challenges persist, including inadequate digital literacy, deficient infrastructure, and resistance to change. The strategic recommendations encompass the provision of fiscal incentives, the implementation of continuous technical training, and the development of data-driven financing ecosystems. Digitalization has the potential to transform the plastic recycling industry by facilitating the transition to a more professional, inclusive, and sustainable system. This transition can be facilitated by collaborative support from government entities, industry leaders, fintech companies, and research institutions.

Abstract

This article examines the role of process innovation in improving operational efficiency within the plastic recycling industry, particularly among small and medium enterprises (SMEs). Operational efficiency serves as a key factor in ensuring both sustainability and profitability amid growing environmental concerns and the global shift toward a circular economy. Through an extensive literature review of international sources, this study highlights how the adoption of technologies such as sensor-based automatic sorting systems, energy-efficient washing, the Internet of Things (IoT), and supply chain digitalization can reduce production costs, enhance product quality, and increase production capacity. However, findings also indicate that several challenges persist, including limited investment capital, low technological literacy, infrastructural disparities, and regulatory uncertainty. Therefore, the success of process innovation in the recycling industry depends heavily on collaborative support from governments, research institutions, industry associations, and NGOs. This paper contributes both theoretically and practically by proposing a conceptual framework that links process innovation, operational efficiency, and sustainability, serving as a foundation for strengthening SMEs toward an inclusive and competitive green industry
