Energy efficiency, greenhouse gas emissions, and cost of rice straw collection in the mekong river delta of vietnam

Publication Date Nov 1, 2016

Abstract

Abstract Collection is still a major challenge in the supply chain of rice straw to prepare feedstock for further use. Straw needs to be gathered from the field and compressed into bales to make it compact and easy to transport. With the introduction of combine harvesters, the collection of rice straw has become harder and more costly. This created negative impacts on other businesses that use rice straw. Mechanization of rice straw collection was introduced in Vietnam in 2013 and it has rapidly developed since. Most of the rice straw produced in the dry season in the Mekong River Delta (MD) of Vietnam is collected for mushroom and for livestock fodder production or for use as mulching materials. In order to quantify the performance of the mechanical operation of rice straw collection, this study conducted an analysis of energy efficiency, greenhouse gas emission (GHGE), and cost of rice straw collection in the MD for five collection machines that operated on the same field, the same rice variety, and the same harvest time under a demonstration in the MD. With rice straw yield of 4.72 t per ha, the collection machines operated at a capacity of 0.87–2.47 t per hour. This mechanized operation can reduce labor requirement by 90%. Specific weight of baled straw was from 73 to 104 kg per cubic meter, which is heavier by 50–100% than that of loose-form straw, at a moisture content of 12.4 (±1.21)% in wet basis. Total energy consumption, ranging from 351 to 588 MJ per ton of straw collected, accounted for 10–17% of the total energy...
