Abstract Thailand's steady growth of urban areas and industrial estates, the construction sector needs to adopt a low‐carbon circular economy (CE) model that emphasizes material circularity and resource efficiency. This research aims to measure the low‐carbon CE of the construction industry through significant representative products, life cycle assessment and material circularity indicator (MCI) were measured on significant representative products materials were evaluated. In the results of the study, it was found that the MCI and GHGs revealed the following results: 1 ton of construction steel products = 0.73 and 2.32 kgCO 2 /ton, 1 bag (50 kg) of mortar and cement products = 0.17 and 16.92 kgCO 2 /bag, 1 m 3 of ready‐mixed concrete at compressive strength 240 kilograms per square centimeter = 0.11 and 253.63 kgCO 2 /m 3 , 1 m 3 of wood and composite wood products = 0.17 and 745.84 kgCO 2 /bag, also 1 m 2 K/W (meters squared Kelvin per Watt) of glass wool insulation = 0.50 and 1.63 kgCO 2 /m 2 K/W, respectively. These values are indicated as national baselines for monitoring CE performance that contribute to the industry's long‐term viability and turn to sustainability in Thailand through the key strategic issues in Thailand's CE and low‐carbon society. The GHGs reduction of 11 million tons is expected, which can also increase the 10% of material circularity, also the estimation of the economic value, by considering the value added from material reduction and the price of carbon credit from construction and demolition waste reduction affect the Thai construction industry by approximately 67 million dollars.

LCA (Life Cycle Assessment) is a well known methodology to assess the impact on the environment over the life cycle of a product, process, or activity. This methodology is based on the LCI (Life Cycle Inventory) database, a data set of all resources (material and energy) that are consumed or emitted in order to produce 1 unit of the product. Because electricity is a basic infrastructure, a Thailand electricity grid LCI database is needed to assess the environmental impact not only for the product used in Thailand, but also for any product that is exported to other countries. A complete LCI database for the electricity grid in Thailand is not yet available, and the LCI database developed in this work applies from the fuel acquisition stage to the production stage. The analysis shows the unique characteristics of the Thailand electricity grid. An LCI database for each type of fuel and for each electricity generation system was developed. The characteristics of each type of fuel and electricity generation system are indicated in terms of Life Cycle GHG (Greenhouse Gas) emissions to reflect their global warming potential. Data on the Life Cycle GHG emission per kWh of electricity produced are also provided. The first Thailand LCI database for the fuels used in the electricity generation system was developed using data obtained from the EGAT (Electricity Generating Authority of Thailand), IPPs (Independent Power Producers), and PTT (Petroleum Authority of Thailand) during the Thai fiscal year 2005 (from October 2004 to September 2005). The database was used to analyze the current situation and the characteristics of the electricity generation system in Thailand and to compare it with the systems used in other developed countries.

Unlike other vegetables, mushroom production requires several substrate ingredients, energy to sterilize the substrate, water to humidify the fruiting house and waste management of the spent substrate and used materials.This work studied the environmental impacts and eco-efficiency of sajor-caju mushroom (Pleurotus sajor-caju (Fr.)Sing.) production in terms of climate change potential, acidification potential, water depletion potential and fossil fuel depletion potential, using life cycle assessment (LCA) method.The results showed that the mushroom production in small and large farms had nearly the same environmental performance.Their environmental impacts were lower and their eco-efficiencies were higher than those for medium-sized farms.This means the medium-sized farms would cause more environmental impacts in order to obtain the same profit as the other two farms.It was found that there was inefficient use of both substrate and energy in the medium-sized farms.This is probably because the medium-sized farm had relatively low financial limitations, compared to the small farms, and relatively less concern over efficient use of resources, compared to the large farms.The reduction of sawdust and rice bran, used as substrate ingredients, as well as wood, used as energy source for sterilization, to the same amounts as those used in the small farms could reduce environmental impacts (5-25%) and improve eco-efficiencies (10-40%) of the medium-sized farms to be close to those for large and small farms.

Perspectives on Life Cycle Assessment Application and Research in Thailand

Life Cycle Assessment (LCA) has been initiated in Thailand since the late 1990s with the first life cycle inventory (LCI) of the electricity grid mix and the offering of the first full graduate course. Since then it has come a long way through the development of the national LCI database and application in various research, industry as well as policy initiatives. LCA has been used extensively as an evaluation and decision tool in agri-food products, energy as well as many other sectors. Many graduate studies as well as research and industrial LCA projects have been performed. Related activities include the proliferation of carbon footprint labeling and application in green purchasing initiatives. Industry has been very actively participating in the carbon footprinting applications, some of them extending their interest to full LCAs for environmental performance evaluation and sustainability reporting. More recently, efforts have also been moving in the direction of looking at life cycle impact assessment methods from a Thailand perspective. Also, with interest in LCA from the policy making perspective, a capacity building effort has been initiated to train researchers in conducting LCA-related research on a sustained basis and ensure that Thailand keeps abreast of the international trends and discussions.
