Feasibility Assessment of Using Cassava Rhizomes for Firing Pottery in Dan Kwian, Thailand


Article Preview

Cassava is one of the most important crops in Nakhon Ratchasima province which grows the most cassava in the Northeast of Thailand. Therefore, a large amount of cassava rhizome is left in the field after harvest. The objectives of this research were to study the feasibility of cassava rhizomes use for Dan Kwian pottery firing in the same province. The analysis consisted of physical properties, heating value and comparing firing the pottery by wood fuel and cassava rhizome. The results were that the cassava rhizomes, with moisture content of about 34.73%, had properties inferior to the woods. When the rhizomes are burned to give thermal energy to pottery products, the temperature profile of the rhizomes is similar to the profile of wood fuels. As a result, the typical quantity of rhizome required, burning time and cost are 3,627 kg, 40 hours and 1,814 baht, respectively, while the values for wood are about 2,600 kg, 34 hours and 2,600 baht, respectively. The cost of the rhizome is less than the wood by around 786 baht. Therefore, using cassava rhizome to replace wood fuel is feasible but it is necessary to control the moisture content to an appropriate level.
