As the demand of oil palm outputs in the world market and Thailand has increased, it results in the oil palm‘s residues which need to be utilized. The study aimed to investigate the utilization of oil palm’s residues and analyze the greenhouse gas emission from the utilization of oil palm’s residues. The study reviewed related literature to obtain concepts, theories, research works, policies, and measures related to the utilization of oil palm’s residues and interviewed to relevant scholars and agencies. The greenhouse gas emission on the utilization of oil palm’s residues were calculated and then compared. The study findings revealed the utilization of the residues and the emission of greenhouse gas as follows: cultivation of straw mushroom from empty palm bunch emitted greenhouse gas 323.1264 KgCO2eq /year; use of oil palm fronds as animal feed emitted greenhouse gas 109.674 KgCO2eq /year; use of empty palm bunch to cover soil emitted greenhouse gas in total 109.674 KgCO2eq /year; composting from residues from palm oil extracting plants emitted greenhouse gas 210.346 KgCO2eq /year, compilation of oil palm fronds in heaps revealed no greenhouse gas emission, and composting from palm bunch emitted greenhouse gas 210.346 KgCO2eq /year.

Palm Fronds

<p>Oil palm fronds (OPF) is widely used as the source of roughage for the farm animals. However, the full potential of OPF as animal feed is limited by their high lignin content which limits the rumen microbe’s access to the cellulose and hemicellulose. White rot fungi (WRF) are a group of fungi belonging to basidiomycete phylum and are commonly found in decaying woody plant. They possess the ability to degrade lignin. This experiment aims to identify the phylum of the best lignin decaying fungi based on their enzymes activity. In this experiment, 11 fungi species were isolated from decaying oil palm fronds. They are labelled as WR1, WR 2, WR3, WR4, WR5, WR6, WR7, WR8, WR9, WR10 and WR11. Their fibernolytic enzyme activities which includes laccase, manganese peroxidase, lignin peroxidase, avicelase, carboxylmethylcellulase and xylanase are analysed using the solid state fermentation method. It <span style="text-decoration: line-through;">is</span> was found that 5 fungi species which are the WR1, WR2, WR4, WR7 and WR10 produced the highest ratio of lignin degrading enzyme to cellulose and hemicellulose degrading enzyme. The fungi are then analysed under microscope to determine the phylum of the fungi. From the observation, the fungi are identified to belong to the phylum basidiomycetes due to presence of clamp connection.</p>

Abstract This study examined energy, greenhouse gas emission and ecological footprint analysis (EFA) of chickpea and lentil cultivation with different mechanization production systems. In lentil production, except for tillage operations, other operations are performed manually and the remaining straw is burned in the field; while in chickpea production, most of the agricultural operations are mechanized and residues are collected, baled and transferred to the warehouse for animal feed. In this paper, for the first time, some of the sustainability indicators are investigated and compared in two different legume production systems. Energy productivity and net energy for chickpea and lentil production were calculated at 0.036, 0.161 and 2373 and 5900 MJ per hectare, respectively. The CO2 emission and ecological carbon footprint were 173 kg CO2−eq and 0.15 global hectare for lentil and 484 and 0.87 for chickpea production. Totally, due to excessive consumption of diesel fuel and lack of proper management, the social cost of emission from straw baling in chickpea production (27.65 dollars per hectare) was higher than burning straw in lentil production (8.77). Multi-objective genetic algorithm results showed the potential of minimizing diesel fuel and fertilizer consumption and no chemical for chickpea production. Overall audition results of two different production systems revealed that traditional lentil production is more sustainable. Therefore, implementations of modern agricultural practices alone are not enough to achieve sustainability in agricultural production systems.

Building construction sector can play a major role in reducing Greenhouse Gas emission through application of technologies aimed at reduction of use of building materials. Energy consumed during production of building materials and components plays a crucial role in creating environmental pollution. India is witnessing high growth in urban and rural housing, which needs more production of building materials. Permanent or semi-permanent type buildings which consume easily available conventional materials like brick, reinforced cement concrete etc. can be made Economic and Eco-friendly by lowering use of energy-consuming building materials through Cost-effective Construction Technologies. Buildings with Cost-effective Construction Technology can be designed within the parameters of the existing Indian Standards. Awareness generation among the users, proper technical and architectural guidance and easy availability of skilled manpower are of utmost importance for promotion of cost-effective technologies in India and to make them as the most acceptable case of sustainable building technologies both in terms of cost and environment.
