Case Study: Enhancing Sustainability in Allahabad’s Bioenergy Project with Ocean HDPE Liners

As the global demand for renewable energy intensifies, the focus on bioenergy projects has increased significantly. These projects harness organic materials to produce sustainable energy while mitigating environmental impact. Ocean Non Wovens is proud to have contributed to a groundbreaking Bioenergy Project in Allahabad, Uttar Pradesh, by supplying and installing Ocean HDPE Liners in two thicknesses—1500 micron and 500 micron—spanning a total area of 13,200 square meters. This case study delves into the project’s details, explores the significance of HDPE liners in bioenergy, and highlights how our products exceeded industry expectations.

Overview of the Bioenergy Project

Located in Allahabad, the Bioenergy Project is part of India’s push toward renewable energy, aligned with the nation’s goal to achieve 175 GW of renewable capacity. This facility processes organic waste, converting it into biogas, compost, and electricity, thus addressing the region’s dual challenges of waste management and energy security. Critical to the success of the project was ensuring environmental protection and the safe containment of organic waste—a challenge that Ocean Non Wovens addressed with its advanced geosynthetics solutions.

Importance of HDPE Liners in Bioenergy Projects

HDPE (High-Density Polyethylene) liners are essential in bioenergy projects, providing impermeable barriers that prevent the leakage of potentially hazardous leachate into surrounding soil and groundwater. These liners are particularly crucial in anaerobic digesters, storage ponds, and landfill capping. Their high chemical resistance, durability, and flexibility make them ideal for containing organic matter and biogas, ensuring operational efficiency and environmental compliance.

Specifications and Installation of Ocean HDPE Liners

1. Ocean HDPE Liner – 1500 Micron (1.5 mm)
   • Quantity: 9240 Sqm
   • Application: Primary containment layer for the anaerobic digestion process.
   • Key Features:
     • High tensile strength, ensuring structural integrity under heavy loads.
     • Superior resistance to chemicals and UV radiation, ensuring long-term durability.
     • Low permeability, which effectively prevents gas and liquid migration.
2. Ocean HDPE Liner – 500 Micron (0.5 mm)
   • Quantity: 3960 Sqm
   • Application: Secondary containment and protective barrier in leachate collection ponds.
   • Key Features:
     • Lightweight yet robust, facilitating easy installation.
     • Excellent puncture resistance to withstand mechanical stresses during operation.
     • High flexibility for seamless installation over uneven surfaces.

Unique Challenges and Solutions

1. Site-Specific Adaptation

The project site posed unique challenges due to its varying soil composition and topography. Ocean Non Wovens conducted an in-depth soil analysis to ensure optimal liner selection and customized the liner installation to conform to the irregular surface contours. This approach minimized the risk of liner displacement and ensured a perfect seal against leakage.

2. Biogas Containment and Optimization

In addition to containing organic waste, the project required efficient biogas collection to maximize energy output. The Ocean HDPE Liner – 1500 micron, with its low permeability and high tensile strength, ensured that biogas remained securely contained, significantly enhancing the system’s efficiency and reducing greenhouse gas emissions.

3. Sustainability and Environmental Compliance

Beyond standard industry requirements, the project aimed for superior environmental compliance. Ocean HDPE Liners helped achieve this by preventing soil and groundwater contamination and enabling safe leachate management. This commitment to sustainability was a core reason the project was awarded environmental certifications, setting a benchmark for future bioenergy projects in India.

Data and Results

• Containment Efficiency: The liners achieved a containment efficiency of over 99.8%, as verified by third-party audits.
• Operational Longevity: Projected liner lifespan exceeds 30 years, ensuring long-term viability.
• Environmental Impact Reduction: Prevented the release of over 500 metric tons of CO₂ equivalent emissions annually, contributing to a greener energy solution.
