Canada’s First Data-Driven Environmental Profile of Abaca Fibre Plant

As the world moves toward responsible sourcing and a zero-waste system, we recognize the need to go beyond claims and provide quantitative evidence that our materials truly make a difference.

In a scientific study conducted by 5Redo, an environmental sustainability lab led by top scientists in Canada, the Clean Market Bag grocery bags were studies on three key performance areas: mechanical durability, industrial compostability, and natural biodegradation. The goal was simple: to verify that our grocery bags can withstand repeated real-world use and return to nature at the end of its life, supporting a circular and low-impact product, if 

Key Findings: Durability Meets Circularity

Laboratory-Verified Durability

The Manila hemp fibre, taken directly from our grocery bag, underwent rigorous mechanical testing modeled on ISO 6330 protocols. After three successive machine wash cycles—mimicking real-world user scenarios—tensile strength testing showed only minor changes in elongation and, notably, a slight increase in ultimate tensile strength.

Why is this important? Abaca’s unique cellular structure, when properly processed, not only preserves but can enhance fiber-to-fiber cohesion with use, slightly increasing load-bearing capacity. For the Clean Market Bag, the practical result is a maximum supported load rising from 34.4 kg (unwashed) to 42.1 kg (post-wash), outperforming most commercial bag textiles while maintaining high standards of reusability and value retention.

Industrial Compostability: Designed for Circularity

Reusable isn’t enough if the end-of-life outcome is landfill. Our samples underwent controlled compostability testing under ISO 20200 conditions (58°C, 90 days). Results confirmed that Manila hemp yarn achieves an average disintegration rate of 89%, essentially meeting the recognized ASTM D6400 criteria for commercial compostable products. Even after strict sieving, barely any original material remained—a powerful testament to alignment between product and planet.

Natural Biodegradability: Demonstrating Responsible Disposal

True sustainability involves operating in harmony with nature. Simulated soil biodegradation trials conducted at 25°C, following ASTM D5988 standards, revealed Manila hemp fibre degrading at a rate almost identical to pure cellulose filter paper—a recognized benchmark for biodegradability controls. Over 100 days, Manila hemp achieved a 48.7% disintegration rate in soil, confirming that Clean Market Bag fibers safely reintegrate into the ecosystem under typical disposal conditions.

Why This Matters

This scientific validation supports Clean Market Bag’s core mission: delivering materials that empower brands to combine style, performance, and environmental stewardship without compromise. Our Manila hemp fiber bags, tested for durability, compostability, and real-world biodegradability, aim to move the conversation beyond aspiration to measurable environmental impact. We openly share our lab report with partners and clients who seek transparent, data-driven assurances.
