Real-World Success Stories
Premium Biofertilizer Powered By Harp’s Biotechnology
Harp’s advanced thermal process locks in 52% Total Organic Carbon. By using our proprietary enzymes and ATAD technology, we minimize carbon loss, reduce emissions, and retain more nutrients.
This results in a superior biofertilizer that sequesters more than twice as much carbon as compost and 73% more than typical fertilizers, delivering greater environmental benefits and improved soil health.
The end-product, which features the highest organic carbon content among similar products, is free from pathogens and odours, making it a safe and high-value soil product.
