Abstract
This research aimed to develop degradable flowerpots from latex sludge compost of concentrated latex factory mixed with cow manure by studying the suitable composition for the production of degradable flowerpot and assessing the economic value of the product. The latex sludge compost used in this study was made by fermenting latex sludge from a concentrated latex factory with cow manure for 50 days. In the production of degradable flowerpots, the experiments were divided into 4 sets with different ratios of latex sludge compost : potting lamduan soil : loamy soil including 100:0:0, 75:20:5, 50:40:10 and 25:60:15 by weight. The starch glue used for forming flowerpots was made from cassava starch mixed with water at the ratio of 1:10. The properties of degradable flowerpots to be evaluated were physical characteristics, water absorption, inflation, porosity and deterioration. The results showed that the degradable flowerpot having the highest water absorption value, inflation value, porosity value and the slowest deterioration was the one made from latex sludge compost : potting lamduan soil : loamy soil with the ratio of 25:60:15. In the assessment of economic impact, it was found that the return on investment of the production of degradable flowerpot was 65.84 with an average net profit of 7.94 baht/unit. This study proposed an approach not only to increase the value of latex sludge compost but also to reduce environmental pollution problems and to reduce waste disposal costs.
