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 plastic waste recycling industry plays a crucial role in reducing environmental impacts while creating economic value through recycling. This study aims to identify strategies for selecting recycled raw materials that can enhance the profitability of the plastic recycling industry. Using a literature review approach, the study explores various sources of raw materials, such as household, industrial, and commercial waste and analyzes their quality, contamination levels, and processing costs. The findings indicate that high-quality raw materials with low contamination levels, such as industrial waste, result in higher production efficiency and lower costs compared to other materials. Additionally, the adoption of modern technologies such as chemical recycling can increase production efficiency by up to 85%. This study contributes by providing a strategic framework for selecting appropriate raw materials, supporting both environmental sustainability and industry profitability.

Abstract

This study explores the strategic significance of innovation and product diversification in enhancing profit growth for MSMEs in the pottery craft sector in Indonesia. The research employs a literature review approach, with a focus on the adaptation of contemporary designs, the use of material combinations, and the expansion of product functions. These strategies enable MSME actors to reach broader market segments, increase selling prices, and create significant economic value. The study indicates a direct correlation between innovation and key financial indicators, including return on investment (ROI), net profit margin, and sales volume. Moreover, the diversification of products has been shown to enhance business resilience in the face of market fluctuations, thereby generating opportunities in the domains of decoration, tourism, and sustainable lifestyles. This study underscores the significance of a collaborative ecosystem comprising designers, government entities, and digital platforms to systematically support the innovation process. The adoption of an integrated innovation approach by pottery MSMEs has the potential to catalyze their transformation into a creative sector that is characterized by competitiveness, adaptability, and sustainability.
