CRITICAL AIR QUALITY ZONING BY USING METEOROLOGICAL STATION DATA AND GOOGLE EARTH ENGINE

2024-09-06T18:01:50+07:00

This study aims to 1) identify critical air areas where pollution emissions have disproportionately severe impacts due to geographical conditions, determined by the proportion of very stable atmospheric conditions, and 2) examine the relationship between PM2.5 and atmospheric stability associated with air pollutant accumulation in the most critical area identified.The Monin-Obukhov Similarity Theory was applied to classify atmospheric stability using cloud cover, wind speed, and temperature data at 10 meters from 20 meteorological stations. Data was collected at 3-hour intervals from 01:00 to 22:00, eight times daily throughout 2023. Geographical data was sourced from Google Earth Engine.

Results identified five critical air areas with the highest proportions of very stable atmospheric conditions: Lampang (51.37%), Kanchanaburi/Thong Pha Phum (50.36%), Nan (49.7%), Mae Hong Son (49.29%), and Phayao (48.66%). Further analysis of Lampang province, the most critical area, revealed a significant relationship between PM2.5 levels and very stable atmospheric conditions. Health-affecting dust levels were present in 67.6% of all atmospheric stability conditions observed. This research contributes the understanding the geographical and meteorological factors influencing air pollution accumulation, potentially informing targeted air quality management strategies in critical areas.

GUIDELINES FOR HOUSEHOLD WASTEWATER MANAGEMENT ALONG THE CHE ME CANAL BY THE WAENG LOCAL COMMUNITY PARTICIPATION, NARATHIWAT PROVINCE

2025-01-09T16:20:43+07:00

This action research aimed to develop guidelines for managing household wastewater along the Che Me Canal in Narathiwat Province through local community self-management mechanisms. The study was conducted in four steps across two phases, including 1) developing and implementing the household wastewater management process along the canal through planning, action, and observation, and 2) expanding the network by reflecting on the outcomes. Content analysis was employed to extract lessons learned and interpret findings from the specifically selected target group meeting. Findings reveal that the wastewater management approach along the Che Me Canal is divided into three levels. 1) At the household level, wastewater is managed at the source by upgrading toilets to meet sanitary standards, composting kitchen food waste, and converting backyard pandan plots into wastewater filtration beds. 2) At the community level, four public policies were introduced, including (1) supporting and promoting household wastewater and source-based solid waste management for canal-side homes, (2) enacting local ordinances, or Hukum Pakat, to designate the Che Me Canal as a conservation area and a community food source, (3) forming a Che Me Canal committee and incorporating follow-up actions into the agenda of subdistrict meetings, and (4) incorporating the Che Me Canal conservation and restoration plan into local development plans. 3) At the network level, a Golok River Basin network was established to collaboratively develop joint measures at the watershed level moving forward.

A STUDY ON THE MANAGEMENT OF WASTE FROM THE THAILAND AROMATIC COCONUT INDUSTRY: A CASE STUDY OF RATCHABURI AND SAMUT SONGKHRAM PROVINCES

2025-01-21T15:51:26+07:00

This research investigates the management of Thailand’s aromatic coconut industry waste, focusing on a case study of Ratchaburi and Samut Songkhram provinces. Primary data, such as processing volumes, amount of waste throughout the product value chain, waste management, and increasing the value-added utilization, were examined. The results from 2023 indicated that both provinces had a coconut planting area of 100,100 rai or 160.16 square kilometers (54.60% of the total), yielding a daily production of 1,630,357 fruits, equivalent to 3,526.53 tons/day (including weight of bunches). While 6.95% of aromatic coconut production was sold as fresh products, the remaining 93.05% was processed into value-added products like peeled coconuts, coconut jelly, and coconut puddings, etc. This processing generated approximately 1,836.14 tons/day of aromatic coconut waste, including peduncles, pedicels, husks, and shells. Currently, both provinces manage 1,420.74 tons/day of aromatic coconut waste through non-utilization methods, such as dumping in public areas, sanitary landfills, or land leveling. To optimize management, a potential solution is to convert aromatic coconut waste into fuel. This approach could replace 200.42 tons of coal per day. (yielding 106.92 TOE/day in energy based on the heating value of biomass). Considering the energy demand of coal-fired boilers in both provinces, which is 1,017.50 tons/day (573.90 TOE/day), this conversion could significantly reduce greenhouse gas emissions by approximately 510.16 TonCO2e/day, aligning with the Bio-Circular-Green Economy (BCG model) for aromatic coconuts.

PRODUCT-SERVICE SYSTEMS DESIGN GUIDELINES FOR SUSTAINABLE PLASTIC FILM WASTE MANAGEMENT BY APPLYING FOCUS GROUP AND CO-CREATION

2025-03-10T15:55:01+07:00

Plastic waste management in Thailand remains a significant issue, particularly for plastic film waste such as food packaging and plastic bags. These materials are widely used but difficult to recycle due to the lack of proper sorting systems. The problem is especially evident in Bangkok, where plastic waste volume is high and waste management systems remain insufficient.

This study aims to analyze the situation of plastic film waste in Bangkok through focus group discussions and co-creation sessions with stakeholders in the waste management system. The objective is to gain in-depth insights into the challenges and opportunities related to plastic film waste handling.

Findings reveal that plastic film waste has low value and is difficult to manage due to its light, bulky, and contaminated nature, making recycling unprofitable. Additionally, consumers lack awareness of proper waste separation, while producers tend to prioritize marketing over environmental sustainability.

The study proposes improvements to the plastic film waste management system, such as an online waste-sorting guide with AI material identification, a database of drop-off points, color-coded trash bags, and small-scale waste cleaning machines. It also recommends promoting mono-material use and clear recycling labels. Incentive systems like return-and-reward schemes and doorstep collection services are suggested to increase recycling efficiency and support a sustainable waste management system and circular economy in the long term.

COMMUNICATION STRATEGY TO ENHANCE PEOPLE’S PARTICIPATION IN PLASTIC WASTE MANAGEMENT: RECOMMENDATIONS FROM QUALITATIVE RESEARCH FINDINGS IN BANGKOK'S WASTE MANAGEMENT DISTRICTS, “MAI TE RUAM PROJECT”

2025-05-02T11:57:16+07:00

This applied research study examines the physical environment of plastic waste management, disposal behaviors, and communication behaviors. It specifically focuses on the Pathumwan and Phaya Thai districts in Bangkok, which are part of the "Mai Te Ruam" (Don't Mix Waste) initiative. Qualitative data are collected from two sources: field observations of 290 samples, and in-depth interviews with 14 small business operators, along with focus group discussions involving 20 consumers.

The physical environment of waste management results indicate that waste disposal occurs most frequently in the afternoon. Pathumwan district has more segregated waste bins than Phaya Thai district. Most people do not separate their waste. The majority dispose of small amounts of waste, 1–2 pieces at a time, and typically mix plastic waste with others.

Descriptive analysis of key informants' behaviors reveals the following results. Small business operators use a moderate to high amount of plastic. Most have a moderate understanding of plastic waste management. Most are familiar with social media such as Facebook, Line, YouTube, and television. They essentially show interest in short news and interviews. The consumer group uses a moderate amount of plastic. Almost all consumers possess a moderate understanding of plastic waste management. They receive information through social media, especially Facebook and Line. Their message interests include short news feeds and news photography or pictorials.

The study provides practical insights for developing communication strategies that can improve plastic waste practices. Four key components for future applications include target audience, desired outcomes, communication channels and content.

2025-05-01T11:32:21+07:00

This research aims to study and analyze the lessons from a project promoting community participation in waste Separation at the source in Chanthaburi Province, focusing on and examining five local administrative organizations (LAOs). Data collection methods included reviewing relevant documents, conducting structured interviews with administrators, project associates, community leaders, residents, and non-participant observation. Data analysis applied the four dimensions of the Balanced Scorecard in conjunction with SWOT analysis. The research findings are as follows: Effectiveness perspective: four LAOs achieved their objectives, with reduced waste management budgets and extension of waste types. Target group perspective: residents were satisfied with participating in the project across all five LAOs. Most project supervisors were heads of departments or directors of public health and environment divisions. LAO personnels participated in policy implementation. Management perspective: activities were designed to manage 4 types of waste, but their limitation of was in monitoring and evaluation. Learning and Development perspective: all LAOs developed their personnel, and three LAOs continuously operated with a focus on improving work processes. Internal factors affecting participation in waste segregation at the source were administrators, personnel, budget, and operational processes. External factors were area conditions, community leaders, community participation, and cooperation from relevant agencies.
