Plastic materials have become indispensable in modern society due to their durability, versatility, and low cost. However, the same durability that makes plastics useful also creates one of the most pressing environmental challenges such as white pollution of our time. At De Eco SR Hygiene Sdn. Bhd. (DESH), we develop biodegradable and compostable polymers know POLYNEX to replace conventional plastics, supporting circular material use, lowering carbon emissions, and protecting ecosystems.

Polynex is an innovative biodegadable & compostable composite material developed using cellulose-based fillers derived from agricultural by-products and selected biopolymers. It is known for their flexibility and mechanical strength. This carefully engineered formulation delivers the performance and durability while achieving complete biodegradation and compostability within months.

Unlike traditional plastics that persist in the environment for centuries and cause microplastic, Polynex breaks down safely without leaving behind toxic residues. It converts to water, carbon dioxide and biomass. Besides the utilization of cellulose from agriculture waste into fabrication of Polynex, it not only helps reduce plastic pollution but also prevents agro-waste from being discarded or openly burned supporting a cleaner, more sustainable circular economy. Polynex is designed to make mulch films, planter bags, bin liners, apron carrier bag and other single use plastics for agriculture, household and commercial use. By combining functionality with true biodegradability & compostability, Polynex offers a simple yet impactful solution to reduce single use plastic waste in daily life.

Reduced Plastic Pollution
Biodegradable materials help minimize long-term accumulation of plastic waste in landfills and natural ecosystems.

Circular Material Lifecycle
Our materials follow a circular lifecycle model where agricultural waste is transformed into sustainable products that can naturally return to the environment after use.  Products are designed with end-of-life degradation in mind, aligning with global sustainability initiatives and ESG frameworks. This approach reduces waste generation while maximizing resource efficiency.

Sustainable Impact
Our biodegradable products utilize renewable agricultural waste such as rice husk biomass. By converting agricultural residues into eco-friendly materials, we support sustainable resource utilization while reducing landfill waste and environmental pollution.

Low Carbon Emission
Bio-based materials derived from agricultural waste can significantly reduce carbon dioxide (CO₂) emissions compared to conventional polyolefin plastics produced from fossil resources. By utilizing renewable biomass, the overall carbon footprint across the material lifecycle can be substantially lower.

• Manufactured using agricultural by-products and renewable resources
• Biodegradable and compostable polymer system
  Reduces long-term plastic pollution and microplastic formation
• Converts agricultural waste into value-added materials
• Durable and flexible for everyday plastic replacement applications
• Compatible with conventional plastic processing technologies
• Supports ESG commitments and Sustainable Development Goals (SDGs)

The world currently produces more than 400 million tonnes of plastic annually, yet less than 10% is recycled, with large quantities entering landfills, terrestrial ecosystems, and aquatic environments. 

Because conventional plastics degrade extremely slowly, large quantities accumulate in landfills, oceans, and soils. Over time, these materials break down into microplastics, small particles that are increasingly being detected in marine environments, freshwater systems, and agricultural soils.

 Studies have shown that microplastics can:

• Disrupt soil microbial activity
• Reduce soil fertility and water retention capacity
• Enter food systems through crops and marine life
• Persist in ecosystems for decades or centuries 

These environmental concerns are driving industries and governments worldwide to transition toward biodegradable and compostable plastics. These materials work just like conventional plastics during use but are designed to break down safely after disposal, reducing long-term environmental impact. Let’s explore how conventional plastics compare with biodegradable and compostable plastics.

Conventional plastics

Conventional plastics are made from non-renewable, petroleum-based resources and are highly persistent in the environment, often taking hundreds of years to degrade. Instead of fully breaking down, they fragment into microplastics that contribute to long-term pollution and pose risks to ecosystems and human health. These materials tend to accumulate in landfills, oceans, and natural environments, and offer limited sustainable end-of-life options, especially when not effectively recycled. 

Biodegradable Materials

Biodegradable materials are designed to break down naturally through biological processes involving microorganisms such as bacteria and fungi. During this process, the material gradually converts into environmentally harmless substances including:

• Carbon dioxide
• Water
• Biomass

This natural breakdown significantly reduces long-term environmental persistence compared to conventional plastics. 

Compostable Materials

Compostable materials are a specialised category of biodegradable materials that degrade under controlled composting conditions within a defined period.

When composted properly, these materials transform into nutrient-rich organic matter that can improve soil health and support plant growth.

Compostable materials are widely used in sustainable packaging and agricultural applications because they support closed-loop resource systems.
