SAWA Updates

Amid the vast rice fields of Nueva Ecija, the Philippines, a small change is opening up big opportunities for the future of agriculture. It is called Alternate Wetting and Drying (AWD) —a simple technique that is gradually inspiring a new way of managing water in rice paddies. Instead of continuously flooding fields as in traditional practices, AWD introduces a new rhythm: allowing water levels to recede until the soil briefly dries, then re-irrigating at the right time. For

Better Soil, Better Year Improve soil quality and agricultural productivity with SAWA Biochar , a nature-based soil amendment designed to enhance soil structure, increase water retention, and support sustainable agriculture while contributing to climate change mitigation. What Is Biochar? Biochar  is a porous carbon material produced through the controlled heating of biomass (agricultural waste) in low-oxygen conditions. SAWA Biochar is specifically developed as a soil amendm

At SAWA, we convert under-utilized agricultural waste into a climate-positive, high-performance soil amendment that supports farmers, improves soil productivity, and strengthens our nation’s circular economy. Our process combines responsible feedstock sourcing, clean pyrolysis technology, and rigorous quality control to produce biochar engineered for long-term performance.
