Journal of Material Cycles and Waste Management · 2025

This study aimed to quantify food waste to facilitate reporting aligned with the Sustainable Development Goals for Thailand. The required data was gathered through interviews covering retail, out-home consumption and households. The data collection was based on statistical sampling at a 95% confidence level with a potential error of less than 10% and included direct measurements for at least 10% of the total number of samples. The results indicated that Thailand generated 12 million tons of food waste per year, which mainly came from households (77%). The food waste index of household, food services and retail were 97, 29 and 16 kg/capita/year, respectively. In addition, discarded food waste from households was mainly edible parts (46%) which were disposed through the municipality waste service (84%), followed by using as animal feed (13%), and composting (2%). The main barrier for households in food waste was unplanned cooking, discarded food items, and lacking knowledge on food waste impacts. Raising public awareness along with supporting laws and provided facilities for waste separation were the key issues for policy recommendations. This study represented the first attempt to develop the national food waste baseline that could be useful for performance tracking towards sustainable food waste management.

Weather Climate and Society · 2024

Abstract Quantifying the total greenhouse gas (GHG) emissions along the whole value chain is essential for effective greenhouse gas management. Two types of the most popular restaurants in Thailand were included in this study: 1) a restaurant that specialized in northeastern Thai cuisine with an area of 94 m 2 and 41 000 clients per year and 2) a restaurant serving Japanese–Thai fusion meals with an area of 284 m 2 with 59 000 clients per year. Notably, the scope 3 GHG emissions were the highest (76%–81% of total emissions). The main contributors at both restaurants were raw material acquisition, followed by transportation of raw materials and waste management. It was suggested that the restaurants should not overlook the major sources of scope 3 GHG emissions, especially in food procurement, transportation from suppliers, and waste management. GHG management measures that could be applied include using local food ingredients, buying raw materials from nearby locations, simulating transport routes to minimize the distance of transport, and separating food wastes and sorting recyclable packaging wastes for further use. In addition, the restaurants could flag low-carbon footprint meals on their menus to engage their customers in contributing to GHG reductions.

Rattanawan Mungkung, Tananon Nudchanate

Weather Climate and Society · 2023

Abstract This study quantified greenhouse gas emissions from indirect activities along the whole value chain of supermarket retailing to derive mitigation measures. Both direct and indirect greenhouse gas emission sources of a supermarket retailing value chain were identified and calculated using the national guidelines for estimating the carbon footprint for organizations, based on a total area of 13 248 m 2 and operating 12 h per day. A scoring matrix was applied that considered the magnitude of emissions, the level of influence, and the risks or opportunities associated with business operations. The scoring results indicated a major contribution from value chain activities that should be included in any greenhouse gas analysis. The calculation revealed that the greenhouse gas emissions from the value chain activities were 33 784 t CO 2 emitted yr −1 or 94% of total emissions. The key contributors were linked to the production of purchased goods and the management of food waste. Thus, value chain activities should not be overlooked in developing efficient greenhouse gas management strategies. Furthermore, purchased products and services carrying a carbon-reduction label should be given priority, and the application of artificial intelligence and innovation could be considered to reduce the amount of food waste from expired goods.

Rattanawan Mungkung, T. Phetcharaburanin

Journal of Insects as Food and Feed · 2023

Insects will be an important alternative food for protein in the future. Crickets, with a high protein level (54-70%) and all the essential amino acids, have emerged as a high potential protein source. Thailand is taking a leading position in Southeast Asia when it comes to producing alternative proteins based on crickets, with an annual production capacity of 3,700 tonnes/year with 1,200 registered farmers. To provide supporting information for sustainable agriculture policy decisions toward food security, carbon footprinting was applied as the analytical tool to assess the environmental performance of house cricket farming and processing into frozen fresh crickets and cricket powder. The inventory data associated with the life cycle of cricket products were collected from 20 farms in the north and 16 farms in the northeast covering small-, medium-, and large-sized farms. In the processing stage, the inventory data were gathered from the internal recording systems of the production processing activities from a local cricket manufacturer. Based on the edible protein content as the functional unit, the carbon footprint values of frozen crickets and cricket powder were 4.6 and 11.3 kgCO 2 e/kg of edible protein, respectively. By calculating the revenue of cricket-based products per carbon footprint, we showed that the cricket powder had higher eco-efficiency values (almost 4 times) than fresh crickets. Furthermore, the net income from cricket farming and processing was 567-69,670 USD/year and the labour productivity was 16-223 USD/worker-day. This information should be very useful for government to support national policy decision-making on promoting and increasing the number of cricket farms, with the aim of enhancing market opportunities, especially in international markets. Cricket farming is expected to offer a livelihood strategy based of sustainable agriculture in Thailand, while making a strong potential contribution toward food security.

Environment Development and Sustainability · 2023

Abstract Riceberry rice has a special characteristic of being specially bred with high nutrients. High-value added products from riceberry are being promoted targeting health-conscious consumers. To provide supporting information for sustainable food systems, environmental footprinting was applied for evaluating the environmental performance of a ready-to-eat product of riceberry rice mixed with kidney red bean called “Riceberry + KU”, developed by Kasetsart University in Thailand. Based on sold unit as the unit of analysis, the carbon footprint of Riceberry + KU was 5.24 gCO 2 e per 300 g. Interestingly, white rice had the highest carbon footprint and riceberry rice as well as the riceberry product had at least 30% lower values. However, using nutrient-based scores, although white rice still had the highest carbon footprint, Riceberry + KU had 80% lower and the riceberry rice had 65% lower values. This resulted from the highest nutritional levels found in Riceberry + KU along with the lower greenhouse gas emissions from riceberry field during the cultivation stage. Similar trends were found in the other impact categories assessed by using life cycle assessment as well. To provide appropriate information to consumers for making more sustainable food choices, the environmental performance based on nutrient quality resulting from different farming systems and processing methods should be used to derive recommendations for moving toward sustainable food systems. The nutrition-environment nexus assessment could be very useful for supporting consumers toward making more sustainable food choices.

International Journal of Agricultural Sustainability · 2022

The sustainability level of current rice farming practices in Thailand was assessed based on in-field data from interviewing 2000 farmers covering six rice varieties and their different production systems. Data were collected on farmers’ characteristics and farming activities according to the 41 requirements of the Sustainable Rice Platform (SRP) standard. The SRP scores ranged from 53 to 81%, with the best performance by Khao Dawk Mali 105 cultivated in rainfed, organic production systems. The key success factors were linked to the formation of a farmer group resulting in very good performance on farm management, Integrated Pest Management, health and safety, and water use. The proposed 12 performance indicators (PIs) interconnected with the 41 requirements are considered appropriate to measure and monitor progress toward sustainable rice cultivation for policy makers. PIs for good governance, affordability of living costs, energy-use efficiency, and life satisfaction could potentially be added, considering the local context in relation to sustainable agriculture goals. The successful cases of SRP-certified rice farms and the benefits from SRP implementation should be conveyed to with other rice farmers to induce wider implementation. The SRP scores and PIs were useful to identify areas requiring priority interventions to make progress toward sustainability.

Sustainability · 2020

Thailand has a strategic national policy to increase organic rice farming. This study firstly applied Life Cycle Assessment for evaluating the quantitative environmental impacts at the regional and national levels to facilitate the national policy decision on the expansion of organic rice cultivation areas. The impact categories of interest included global warming, terrestrial acidification, freshwater eutrophication, terrestrial ecotoxicity, and freshwater ecotoxicity, and the life cycle impact assessment method applied was ReCiPe. The results showed that the life cycle environmental impacts from organic rice cultivation in the nine provinces in the North were lower than those from the 12 provinces in the Northeast, due mainly to the higher yields and lower use of fertilizers in the former. The methane emissions in the North (11,147 kg CO2e/ha) were similar to those in the Northeast (11,378 kg CO2e/ha). However, nitrous oxide emissions in the Northeast were higher than in the North due to the higher amounts of fertilizer used. If Thailand expands the rice farming by 50% in the North and by 50% in the Northeast, the greenhouse gas emissions could be reduced from 11,400 to 11,100 kg CO2e/ha, but the impacts of terrestrial acidification, freshwater eutrophication, terrestrial ecotoxicity, and freshwater ecotoxicity could be increased by 0.0257 kg PO4e (95%), 0.508 kg 1,4-DBe (53%), and 33.1 kg 1,4-DBe (17%), respectively. To reduce the global warming as well as other environmental impacts, Thailand should expand rice farming areas to the North. This information could be useful for supporting the policy decisions on which areas the organic rice farming should be expanded in to minimize the potential life cycle environmental impacts.

Journal of Agricultural Science · 2019

A meat-free diet and the aging society cause some of the health problems. One of that was the deficiency of some essential amino acid in the diets. Riceberry has recently been developed in Thailand. This new variety of colored rice has a dark purple seed coat containing anthocyanin which acts as an antioxidant. Similar to normal rice, riceberry lacks lysine which plays an important role in maintaining body systems through hormone release and muscle mass maintenance. To enrich ready-to-eat rice products, red bean was added as a natural amino acid source. This formulated product had higher protein and ash content, while energy, fat and carbohydrate content were not different from the control. The essential amino acid profile of the product was complete and product shelf life was 6 months with an unchanged texture. Anthocyanin and antioxidant capacity of the product decreased with storage time. This product suited a wide range of consumers and was convenient for modern lifestyles that demand healthy, ready-to-eat foodstuffs.

Hemp is a non-psychoactive (less than 1 % tetrahydrocannabinol) variety of Cannabis sativa L. It is cultivated on hills and used mainly for textiles. Hemp requires less water and pesticides. It grows fast (3 - 4 m in 3 months) and has a high carbon sequestration rate of 1.67 kg CO2-eq per kg of hemp fibre. The local hemp in Thailand is the Rpf3 species developed by the Highland Research and Development Institute. This study aims at exploring the potential use of hemp for eco-building materials to meet the increasing demands for green buildings by applying the upcycling design concept. Hemp stalks left after fibre harvesting were sun dried before ground into small pieces of varying sizes. Artificial stones (polyester-resin solid surface material) left over from production processes were also collected. Hemp materials and artificial stone scraps were used at different proportions to develop a new composite called Hempstone. The study found that Hempstone did not require the drying process; hemp fibers helped absorb the moisture. Hemp fibres also offered unique natural aesthetic. Quality tests were conducted to ensure that Hempstone was fit for use in construction. Life Cycle Assessment (LCA) was performed to identify the potential reduction of environmental impacts of typical artificial stone and Hempstone. The results indicated that the Hempstone sheet (0.82 x 3.04 x 0.012 m) with 10 % of hemp-stalks (6 - 10 mm size) and 7.5 % or 10 % by weight of artificial stone scraps performed best with the potential reduction of environmental impacts by 40 % on climate change, 42 % on freshwater eutrophication, 55 % on terrestrial eco-toxicity and 60 % on terrestrial eco-toxicity. With the growing pursuit of green buildings, these reductions show that the potential use of hemp in local eco-building materials to help reducing impact on the environment.

Rice cultivation is a vital economic sector of many countries in Asia, including Thailand, with the well-being of people relying significantly on selling rice commodities. Water-intensive rice cultivation is facing the challenge of water scarcity. The study assessed the volumetric freshwater use and water scarcity footprint of the major and second rice cultivation systems in the Chao Phraya, Tha Chin, Mun, and Chi watersheds of Thailand. The results revealed that a wide range of freshwater use, i.e., 0.9–3.0 m3/kg of major rice and 0.9–2.3 m3/kg of second rice, and a high water use of rice was found among the watersheds in the northeastern region, like the Mun and Chi watersheds. However, the water scarcity footprint results showed that the second rice cultivation in watersheds, like in Chao Phraya and Tha Chin in the central region, need to be focused for improving the irrigation water use efficiency. The alternate wetting and drying (AWD) method was found to be a promising approach for substituting the pre-germinated seed broadcasting system to enhance the water use efficiency of second rice cultivation in the central region. Recommendations vis-à-vis the use of the water stress index as a tool for agricultural zoning policy were also discussed.

Hemp is a non-psychoactive (less than 1% tetrahydrocannabinol) variety of Cannabis sativa L. It is cultivated on hills and used mainly for textiles. Hemp requires less water and pesticides. It grows fast (4-5 meters in 3-4 months) and has a high carbon sequestration rate of 1.36 kgCO 2 e per kg of hemp fiber. This study aims at exploring the potential use of hemp for construction materials. By applying the upcycling design concept, hemp stalks left after fibre harvesting were sun dried before grinding into small pieces of varying sizes. In addition, artificial stones (polyester-resin solid surface material) left over from production processes was also collected. Hemp materials and artificial stone scraps were used at different proportions to develop a new composite called Hempstone. The study found that Hempstone did not require the drying process; hemp fibers helped absorb the moisture. Hemp fibers also offered unique natural aesthetic. Quality tests were conducted to ensure that Hempstone was fit for use in construction. LCA (Life Cycle Assessment) was performed to identify the potential reduction of environmental impacts of typical artificial stone and Hempstone. The results indicated that the Hempstone sheet (0.823.040.012m) with 10% of hemp-stalks (5 mm size) and 7.5% or 10% by weight of artificial stone scraps performed best with the potential reduction of environmental impacts by 40% on climate change, 42% on freshwater eutrophication, 55% on terrestrial ecotoxicity and 60% on terrestrial ecotoxicity. Hence, the Hempstone sheet with 10% of hemp-stalk material and 10% of artificial stone scraps complies with the UPCYCLE Carbon Footprint certification and labelling requirement of minimum scrap content of 20% by weight. With the growing pursuit of green buildings, these reductions

There is no indicator measuring Thailand’s green growth by valuing the resource degradation and environmental damage costs. This article aims to estimate Thailand’s green gross domestic (GDP) that takes into account environmental damage costs with the detailed analysis on the agricultural sector using the Economic Input Output - Life Cycle Assessment (EIO-LCA) approach. The representative product in each sector was selected based on the available life cycle inventory data, economic values and their magnitude of impacts. Here we find that oil palm cultivation (Sector 011 in the economic input-output table), fibre crops (Sector 013), rice cultivation using chemicals (Sector 001), coffee-tea-cocao (Sector 015), and coconut growing (Sector 010), respectively, generated the highest environmental damage value. This study revealed that the total environmental damage costs of agricultural products was $22.05 million per year accounting for only 0.1003 percent of total GDP in agricultural sector while the total environmental damage cost from all sectors is equal to $36,950.79 million accounting for 14.58 of total GDP.
