COMPOST PRODUCTION FROM ORGANIC HOUSEHOLD WASTE: MODEL IN TUY HOA CITY, PHU YEN PROVINCE

Abstract

Composting is an effective solution for treating organic waste and producing compost, a good soil amendment and organic fertilizer. This study tested the use of 30 household scale compost bins to produce fertilizer from household organic waste in Tuy Hoa city, Phu Yen province in 2024. The study evaluated the potential for organic waste treatment at the household level using compost bins. For Tuy Hoa city, composting could contribute to processing about 32.04 tons of organic waste per day, reducing about 17.8% of the waste that needs to be collected and treated in Tuy Hoa city. Study results show that the average amount of organic waste processed per household is 2.25 kg/day. 100% of households are satisfied with the compost bin, with 57.1% of respondents preferring a separate compost bin at home and 42.9% choosing to compost either at home or in public, depending on conditions. Additionally, 82.1% of respondents are willing to compost waste in public places at larger scale units. The compost created is used by households to nourish flowers, ornamental plants, vegetables and fruit trees, completely replacing chemical fertilizers and contributing to the development of organic agriculture. Besides household compost bins, centralized compost bins and solid fertilizer products are also recommended. The research results show that household composting has great potential to become a widely -implemented strategy in localities, contributing to waste management, creating organic fertilizer for agriculture, and serving the goals of sustainable development and environmental protection.
