Sustainability in agriculture and industry is essential for balancing economic growth with environmental responsibilities. Thailand, as a leading global producer and exporter of natural rubber, faces significant challenges in integrating sustainable practices within its extensive rubber industry. The environmental integrity dimension target indicators of the Sustainability Assessment of Food and Agriculture Systems (SAFA) framework are used in this study to assess the sustainability of Thailand's rubber industry across the rubber plantations and intermediate rubber processing sectors. The sustainability results obtained were integrated with a comparative analysis of Thai legal compliance. Data were collected via structured questionnaires from farmers and intermediate rubber facilities across major cultivation areas in Thailand. The finding revealed both alignments and significant discrepancies between the sustainability assessment results of the rubber sector and the legal compliance evaluation. This study identifies four sustainability performance scenarios based on legal compliance and indicators. It recommends maintaining standards where sustainability performance aligns with legal requirements, offering support and incentives where performance falls below legal requirements, and promoting certification and legal upgrades where performance exceeds requirements. For indicators not yet covered by law, particularly GHG reduction, new legislation and foundational enforcement mechanisms are essential to ensure long-term sustainability progress across both sectors. • SAFA and legal frameworks assessed sustainability in Thailand’s rubber industry. • Sustainability is grouped into four scenarios by legal compliance and performance. • Plantations showed limited compliance due to regulatory gaps. • Processing industries performed better under stronger laws and enforcement. • Policy reforms needed for GHG, waste, and renewable energy improvements.

Sustainable Production and Consumption · 2024

Thailand has set a maximum biodiesel production target of 11.0 million liters per day in 2037; biodiesels produced from fatty acid methyl ester from palm oil is blended with fossil diesel . The alternative biodiesels include bio‑hydrogenated diesel and partially hydrogenated fatty acid methyl ester which can have higher blending percentages with fossil diesel. The total land and water ecosystem requirements for providing resources and absorbing emissions including cropland, energy, the forest, and built-up land for biodiesel production were assessed by ecological footprint to support the sustainable development of the biodiesel production target while considering climate change . In the existing condition, with production at 4.28 million liters per day, the ecological footprints of fatty acid methyl ester, hydrogenated fatty acid methyl ester, and bio‑hydrogenated diesel were 5.46, 5.51, and 4.09 million global hectare/year, respectively. Water and cropland were the major sources accounting for 67 % and 14 %, respectively. For the production of 11.0 million liters per day under Representative Concentration Pathway 8.5, with maximization of fresh fruit bunches productivity and oil percentage, the ecological footprints of fatty acid methyl ester, hydrogenated fatty acid methyl ester, and bio‑hydrogenated diesel were 9.38, 9.89, and 7.29 million global hectare/year, respectively, whereas for business-as-usual fresh fruit bunch productivity and oil percentage, these values increased to 14.5, 15.0, and 11.3 million global hectare/year, respectively. When only fatty acid methyl ester is used, the plantation area must be increased by between 741,862 and 802,281 ha. Increase in yield of oil palm plantation, percentage palm oil, and promotion of bio‑hydrogenated diesel production should be implemented to decrease the amount of resources used for bio-based diesel production.

The performance capability of granular activated carbon (GAC) adsorption in terms of disinfection by-product (DBPs) removal was investigated with synthetic water containing 1) trihalomethanes (THMs), 2) haloacetronitriles (HANs), and 3) Mix-THMs & HANs. The initial 20 min of adsorption resulted in the maximum adsorption rate, with the total THMs, total HANs, and total Mix-THMs & HANs being 4.972, 2.071, and 6.460 µg/gGAC-min, respectively. GAC dosage affects the adsorption selectivity of THMs and HANs. Under a low GAC dosage, the selectivity of GAC adsorbs more bromo-THMs than chloro-THMs. The adsorption selectivity of THMs on GAC following bromoform > dibromochloromethane > bromodichloromethane > chloroform was investigated. As the GAC concentration increased, the selectivity of THM adsorption by GAC became comparable. Chloro-HAN, in contrast to THMs, has a higher adsorption selectivity than bromo-HAN. Trichloroacetonitrile was removed by GAC more rapidly than the other HAN species when the GAC dose was increased. The toxin of bromoform was primarily eliminated through GAC adsorption, caused by a greater removal rate than that of the other THMs. As an implemented measure, GAC is introduced to reduce THMs and HANs and the toxic contents associated with THMs and HANs.

Combining dissolved organic matter (DOM) in raw water (RW) with DOM in treated wastewater (TWW) can react with chlorine and pose emerging disinfection by-products (DBPs). This study evaluated DOM based on the molecular weight (MW) size fractionation, trihalomethane, iodinated-trihalomethane, haloacetonitrile, and trichloronitromethane formation potential (THMFP, I-THMFP, HANFP, and TCNMFP) of the RW from the U-Tapao Canal, Songkhla, Thailand and the RW mixed with TWW (RW + TWW) samples. The RW and RW + TWW were treated by coagulation with poly aluminum chloride. The DOM of RW and RW + TWW and their treated water was distributed most in the MW below 1 kDa. The MWs of 3-10 kDa and 1-3 kDa were the active DOM involved in the specific THMFP for the RW + TWW. The MW of < 1 kDa in the RW + TWW resulted in a slightly high specific I-THMFP and HANFP. The MW of 1 - 3 kDa in the coagulated samples had a high specific I-THMFP. The MW of > 10 kDa in the coagulated RW + TWW was a precursor for a particular HANFP. Monitoring systems for measuring the level of TWW mixed with RW and an effective process to enhance the efficiency of traditional water treatment must be set up to produce a consumer-safe water supply.

Dissolved organic carbon (DOC), microplastics (MPs), and silver nanoparticles (AgNPs) in water are of major concern because of their direct and indirect toxic effects on aquatic organisms and human exposure via water. This work investigated the effect of poly aluminum chloride (PACl) coagulation for reducing DOC, MPs, and AgNPs. This work used water from a canal in Thailand with a DOC of 5.2 mg/L in the experiment. AgNPs of 5-20 mg/L were added to canal water to create synthetic water for the PACl coagulation. Polyethylene and polypropylene (PP) type MPs were identified in the raw water with Fourier transform infrared spectroscopy. Coagulation with 15 mg/L of PACl performed better in the PP removal. The PACl coagulation at dosages of 15, 40, and 70 mg/L removed DOC by 16-20%, 44-52%, and 46-63% and AgNPs by 34-90%, 53-93%, and 81-95%, respectively. The presence of AgNPs at high levels could inhibit the efficiency of DOC reduction by the PACl coagulation. The FESEM identified the adsorption of silver-containing nanoparticles onto the flocs with increased dosages of PACl. So, PACl is a coagulant in the removal of AgNPs that can reduce health hazards and eco-toxicological risks in water sources due to the release of silver.

Abstract The natural rubber industry has played a vital role in Thailand’s economic, environmental, and social contexts. Therefore, sustainable rubber production is a significant concern. At present, a wide variety of international tools has been developed to assess the agricultural sector’s sustainability performance. The Food and Agriculture Organization of the United Nations developed the Sustainability Assessment of Food and Agriculture systems ( SAFA) in 2013. Environmental integrity is one of the dimensions of sustainability in SAFA. SAFA is applied to assess the impact of agriculture operations on the environment. This research aims to assess suitable environmental integrity indicators in compliance with SAFA for rubber plantations in Thailand. The system boundary is set to cover rubber plantations, harvesting of fresh latex, and rubber tree felling. This work conducted focus group discussions, using the SAFA, guidelines, indicators, and tools for rubber plantations, the review process by rubber plantation experts, representatives of rubber associations, SAFA researchers, and environmental scholars, and site visits to interview rubber farmers in the south, northeast, and north of Thailand. Environmental themes, including the atmosphere, water, land, biodiversity, and material and energy were included in assessing the environmental integrity of a rubber plantation. Animal welfare was not included.

IOP Conference Series Materials Science and Engineering · 2021

Abstract This research is aimed at determining the reduction of chloride in the raw water of a water supply plant using nanofiltration and reverse osmosis. Raw water was prepared by adding NaCl at the concentrations of 300 and 600 mg/L. This work used a PACl at 15 mg/L as the pre-treatment for removing turbidity and DOC. Coagulated water was filtered with GF/C filter as the filtration process for minimizing membrane blockage. At chloride concentrations of 300 and 600 mg/L, the flux values were in the range of 66.7-70.0 and 62.8–65.0 L/m 2-h for NF-270 and 17.2–20.6 and 18.3-20.8 L/m 2-h for TW-30, respectively. The performance capabilities of NF-270 and TW-30 for reducing chloride were significantly different. NF-270 and TW-30 membranes were able to reduce chloride by 67 % and 92 % at the added dose of 300 mg/L, respectively. At the added amount of 600 mg/L, NF-270 and TW-30 membranes could reduce chloride by 63 % and 85 %, respectively. In the case of chloride in raw water at a concentration lower than 600 mg/L, the nanofiltration is suitable for removing chloride in regards to the low operation costs compared with the reverse osmosis. Nanofiltration could reduce chloride to lower concentration levels than the water supply standards of the Provincial Waterworks Authority.

Journal of Environmental Science and Health Part A · 2019

Raw water (RW) from the Bangkok and Sing Buri water treatment plants located on the Chao Phraya River, river water, domestic wastewater (WW), and treated wastewater (TWW) from two wastewater treatment plants in Thailand were collected three times to investigate disinfection by-products' (DBPs) formation potential (FP) including trihalomethane FP (THMFP), iodo-THMFP (I-THMFP), haloacetonitriles FP (HANFP), and trichloronitromethane FP (TCNMFP). High THMFP levels were observed in river water, WW, and TWW. Considering average value, the THMFP of TWW was about two times higher than that of RW. Relatively high levels of I-THMFP were found in WW and TWW. The I-THMFP of TWW was three to seven times higher than that of RW. The HANFP of TWW was one to three times higher than that of RW. High levels of TCNMFP were found in WW and TWW. TCNMFP of TWW was six to thirteen times higher than that of RW. The discharge of TWW to RW must be prevented and controlled. The moderately positive linear relationship was obtained between dissolved organic carbon and TCNMFP in TWW. Considering measured weight concentration, THMFP was found as the highest DBPs. The highest lethal concentration 50-weighted and lowest cytotoxicity-weighted concentrations of DBPs were determined for HANFP.

Raw water from the Banglen (BL) water treatment plant (WTP) and Bangkhen (BK) WTP in central Thailand and Hatyai (HY) WTP in southern Thailand was investigated for dissolved organic nitrogen (DON) reduction. The DON(mg N/L) and the dissolved organic carbon (DOC)/DON ratio were 0.34 and 21, 0.24 and 18, and 1.12 and 3 for the raw waters from BL, BK, and HY WTPs, respectively. Polyaluminum chloride (PACl) dosages of 150, 80, and 40 mg/L at pH 7 were the optimal coagulation conditions for the raw waters from BL, BK, and HY WTPs, respectively, and could reduce DON by 50%, 42%, and 42%, respectively. PACl and powder activated carbon (PAC, both in mg/L) at 150 and 20, 80 and 20, and 40 and 60 could reduce DON in the raw waters from BL, BK, and HY WTPs by 71%, 67%, and 29%, respectively. DOC/DON values of water treated with PACl were similar to those of raw water. DOC/DON values of water treated with PACl and PAC were lower than those of raw water. N-nitrosodimethylamine (NDMA) formation potentials of raw water, water treated with PACl, or both PACl and PAC, and organic fractions of BL, BK, and HY WTPs were below the detection limits of 542 and 237 ng/L, respectively. Reductions in fluorescence intensities of tryptophan-like substances at peaks 240/350 and 280/350 (nmEx/nmEm) were moderately (correlation coefficient, R = 0.85 and 0.86) and fairly (R = 0.59, 0.67, and 0.75) correlated with DON reduction.
