Destinação de resíduos sólidos industriais no setor de envase em uma indústria de óleo

Abstract

The generation and improper disposal of Industrial Solid Waste (ISW) pose persistent environmental challenges. Historically, the lack of concern for proper waste disposal has resulted in negative impacts. In the current context, inefficient management of these wastes, especially in the industrial sector, not only threatens local ecosystems but also leads to significant environmental liabilities for companies. This work addresses efficient waste management through a multicriteria analysis for the careful selection of buyers in different categories of industrial solid waste, including cardboard, preform, dirty bottle, drum, plastic, and pallet. Utilizing quality tools, specifically the PDCA cycle (Plan, Do, Check, and Action), only the initial stage, Planning, was employed. Other supporting tools, such as 5W2H (What, Why, Where, When, Who, How, and How much), and the SMARTER decision support method (Simple Multi-Attribute Rating Technique using Exploiting Rankings), enhance decision-making, ensuring well-defined processes and aligned goals. The multicriteria analysis considers factors such as the variety of waste collected by the partner, certification, monetary value paid per kilogram, collection capacity in volume, and distance between the industry and the partner collector, with assigned weights for a balanced multi-attribute evaluation. The annual estimate reveals a substantial total of 320,867,200 kilograms of waste. By addressing waste management, the study seeks sustainable alternatives that not only contribute to environmental preservation but also generate significant revenue. The annual expense for waste disposal was R$ 270,000.00; however, with the new disposal strategies, the projection is a total revenue of R$ 228,780.00 per year. This represents a net gain of R$ 498,780.00, providing the company with an ecological financial advantage. This study not only contributes to effective environmental management but also demonstrates the practical application of quality tools to improve environmental and financial practices, reflecting a commitment to sustainability and environmental responsibility.
