- In-house QC and performance testing
- Strategic location at Port Klang, Malaysia
- Faster curing and higher throughput
Why Our Coating Technology Performs Better
Wastech is an agri-technology company with decades of experience in fertiliser manufacturing and precision agriculture across Malaysia, Hong Kong, and Indonesia. Beyond manufacturing, our work is centred on translating advanced coating technology into measurable field performance, improving nutrient efficiency, and enabling more sustainable crop production at scale.
Thin, Durable, and Uniform Coating
We apply an ultra-thin coating of only 20–30 microns that remains flexible and durable. This allows effective nutrient control while maintaining granule strength during handling, transport, and application.
Wide Substrate Compatibility
Our coating technology is compatible with a wide range of fertiliser substrates, across different sizes and shapes, providing flexibility for standard and custom formulations.
Higher Nutrient Analysis
Lower coating weight means more room for nutrients. This results in higher nutrient analysis compared to conventional coated fertilisers, without compromising release control.
Customised Nutrient Longevity
By adjusting coating weight and thickness, nutrient release can be tailored to specific crops, climates, and growing seasons. This ensuring nutrients are released in line with crop demand across different growth stages.
Predictable and Controlled Nutrient Release
Our advanced coating technology is designed to regulate nutrient release with greater precision and reliability. Laboratory performance tests demonstrate a steady and predictable release pattern over time, allowing crops to receive nutrients more consistently throughout the growing cycle. This controlled release behaviour helps reduce sudden nutrient losses and supports more stable plant growth under real field conditions.

PurActive® Fertilisers Coating Process
PurActive® coating technology forms a protective polymer layer around each fertiliser granule. This layer regulates how moisture enters the granule and how nutrients are released, ensuring a steady and predictable nutrient supply for crops.
01.
Heating
The raw fertiliser particle is prepared for coating using low-heat technology.
02.
Spraying
An advanced polymer layer is sprayed directly onto the surface of the fertiliser.
03.
Adhesion
The polymer layer sticks and begins to form a protective shell around the
particle.
04.
Coating Particle
The finished fertiliser is now fully encased in a shell, ready to release
nutrients slowly over time.
Our Process Advantages
Our coating services are enabled by patented low-heat manufacturing technology, delivering faster curing, lower energy use, solvent-free processing, and flexible production without compromising coating quality.
Curing Time and Faster Reaction
Our curing and batch processing time is approximately five times faster than traditional controlled-release technologies, enabling higher throughput, shorter lead times, and more efficient production.
Low-Temperature Coating Process
Operating at temperatures below 70°C allows the safe incorporation of temperature-sensitive additives such as micronutrients, microbial inputs, and biostimulants without degradation.
Flexible Batch and Continuous Processing
A hybrid batch and continuous process combines flexibility with efficiency, allowing us to handle custom formulations while maintaining production consistency at scale.
Did you know?
Unlike conventional sulfur-coated or basic protective-coated fertilisers, our next-generation polymer coating forms a flexible, uniform membrane that enables predictable nutrient release, avoiding cracking or burst release while allowing customisable longevity and scalable production for modern agriculture.

Stop Nutrient Waste
Our controlled-release coating technology is designed to minimise nutrient losses to both air and soil while delivering nutrients in a precise, plant-available manner. By improving the synchronisation between nutrient release and crop uptake, we help reduce waste, improve efficiency, and support more sustainable nutrient management.
Key benefits include:
- Reduced nutrient leaching into soil and groundwater
- Lower nutrient losses through volatilisation
- Reduced nitrous oxide (N₂O) emissions
- Improved nutrient uptake efficiency by crops
Performance outcomes based on controlled-release fertiliser technology compared to conventional uncoated fertilisers.

Reduces Volatisation
Lessens NO Emissions
Recognised for Sustainability & Performance
Our approach to controlled-release fertilisers focuses on reducing environmental impact while delivering measurable benefits to growers. Our technology partner, Pursell Agri-Tech, is a top performer in the Enhanced Efficiency Fertilizer Challenge, hosted by the U.S. Environmental Protection Agency (EPA), U.S. Department of Agriculture (USDA), and the American Corn Growers Association. This recognition reflects the proven ability of our controlled-release fertilisers to deliver environmental benefits while supporting stronger crop performance for growers.
