Improvement of Environmental Management for the Reduction of Environmental Costs in a Tannery in Trujillo, Peru (2025)

Abstract

The present study aims to improve environmental management at Curtiembre & Servicios Libertad S.A.C. in Trujillo - La Libertad to reduce its environmental impacts and operating costs. Four main causes of environmental problems were identified: environmental regulatory non-compliance, industrial effluent contamination, inadequate management of hazardous waste, and lack of control of environmental parameters. These problems affected production processes, the environment, and the company's profitability. To address this, an Environmental Management Plan, a Contingency Plan, and a Monitoring and Control Plan were proposed as improvement measures. The implementation of these plans reduced economic loss from S/. 22,500.00 to S/. 4,200.00, resulting in a significant economic benefit for the tannery. The economic-financial evaluation of the proposal showed an NPV of S/. 29,184.39, an IRR of 95.16%, a payback period of 6.90 months, and a Benefit-Cost ratio of 1.6, supporting the economic viability of the proposed improvements.
