Reuse of Solid Waste Generated from the Bangladesh Leather Sector: Opportunities, Challenges, and Future Directions
Abstract
The leather industry is one of Bangladesh's major export-oriented sectors, contributing significantly to employment and foreign exchange earnings. However, leather processing generates a large quantity of solid waste from raw hides to finished leather production. Proper utilization of these wastes can create value-added products, reduce environmental pollution, and support the development of a circular economy. This article discusses the classification of leather solid wastes, potential utilization methods, products that can be manufactured, challenges in Bangladesh, and international experiences that may support sustainable waste management.
1. Introduction
Bangladesh processes millions of cattle hides and skins every year. During the conversion of raw hides into finished leather, approximately 40–50% of the raw material becomes solid waste. Most of these wastes are either dumped in landfills or improperly disposed of, causing environmental and public health concerns.
Developing technologies for recycling and reuse of leather waste offers opportunities for:
• Environmental protection
• Resource efficiency
• Additional income generation
• New industrial sectors
• Green employment opportunities
2. Leather Solid Wastes
Solid wastes from leather production generate from different stage of production. Below table shown their characteristics, possible utilizations and Bi-products that we can be used in our daily life.

3. Major Problems in Bangladesh
Despite the significant potential, Bangladesh faces several challenges.
3.1 Lack of Segregation
Different wastes are often mixed together, reducing recycling opportunities.
3.2 Limited Technology
Advanced technologies for collagen extraction, chromium recovery, and composite manufacturing are limited.
3.3 Insufficient Investment
Few investors are interested in waste recycling industries.
3.4 Environmental Concerns
Improper disposal causes:
• Water pollution
• Soil contamination
• Odor problems
• Health hazards
3.5 Lack of Skilled Human Resources
There is limited expertise in leather waste valorization technologies.
3.6 Weak Regulatory Enforcement
Environmental regulations exist but implementation remains inadequate.
4. International Experiences
Several countries have successfully developed leather waste recycling industries.
Italy
• Leather fiberboard manufacturing
• Luxury recycled leather products
• Circular economy practices
India
• Collagen extraction industries
• Chromium recovery plants
• Gelatin production
China
• Large-scale leather waste recycling
• Composite material manufacturing
Turkey
• Leather board and insulation materials
• Waste-to-energy technologies
Brazil
• Organic fertilizer production
• Biogas generation from fleshing wastes
5. How Bangladesh Can Obtain International Support
5.1 Technology Transfer
Collaboration with advanced leather-producing countries can provide:
• Recycling technologies
• Equipment
• Technical expertise
5.2 Joint Research Programs
Universities and research institutes can establish collaborative projects.
5.3 Training and Capacity Building
Engineers and technicians can receive international training.
5.4 International Funding
Support can be sought from:
• Development agencies
• Climate funds
• Circular economy initiatives
5.5 Industry Partnerships
Partnerships with foreign recycling companies can facilitate investment and technology adoption.
6. Recommendations
1. Establish waste segregation systems in tanneries.
2. Develop centralized leather waste processing facilities.
3. Promote research and innovation.
4. Encourage private investment.
5. Strengthen environmental regulations.
6. Develop international collaborations.
7. Provide training programs for industry professionals.
8. Introduce incentives for recycling industries.
7. Conclusion
Leather solid waste should no longer be considered a disposal problem but rather a valuable secondary resource. Bangladesh has substantial opportunities to convert leather waste into high-value products such as collagen, gelatine, fertilizers, leather boards and biodiesel. Through technology transfer, international cooperation, investment, and policy support, the country can establish a sustainable circular economy in the leather sector and enhance both environmental protection and economic growth.
