“…This problem reached a crisis when in March 2019, for several days, the PM 2.5 μm and PM 10 μm levels were higher than the national standard of 25 µg m −3 and 50 µg m −3 . Even though the Thai government has introduced laws and attempted to manage haze and forest fires since 2006, air pollution has been a persisting problem (Pardthaisong et al 2018 ; Phetpradap 2020 ).…”

This study aimed to focus on the design and development of low-cost do-it-yourself (DIY) air purifiers, using a ventilating fan, air pump, water pump, and an ultrasonic generator that can be used during the haze pollution. Six types of household air purifiers were fabricated. The amount of particulate matter (PM) and carbon dioxide (CO 2 ) levels were recorded at 0, 10, 20, 30, and 60 min (min), then, repeated 3 times. After 10 min of the 3rd experiment of each study, the last measurement of air pollution would be recorded. The results showed at 60 min, the high-efficiency particulate air (HEPA) filter and electrostatic fiber was the best technique regarding reduction of PM and CO 2 levels. The highest PM reduction rate had occurred at 30 min using an air pump procedure (99.330 to 100%). The CO 2 levels of all experiments had fluctuated at different times. After 10 min of a closed machine, PM levels of all air purifier systems were decreased, except HEPA filter and electrostatic fiber types. In conclusion, the best method for reducing particulate matter and cost without taking humidity into account is an air pump technique, whereas the HEPA filter and electrostatic fiber method is the best choice for lowering PM levels without increasing humidity and vapor production.

“…In Southeast Asia, people have been suffering from the incidence of seasonal vegetative fires, also called “slash-and-burn” farming methods, which entails burning trees and plants on the farms because these are the traditional low-cost procedures to create nutrient ash and eradicate weeds ( Cheong et al, 2019 ). Over the past decade Thailand, especially Chiang Mai, the second largest province of Thailand, has faced this haze problem, particularly in the summer season from February to May ( Pardthaisong et al, 2018 ).…”

“…Burning of residue can cause air pollution problem, smog and dust. Pardthaisong et al (2018) said that this problem has affected Northern provinces of Thailand tremendously, not only economic and tourism sectors, but also health of residents in both short and long term. Biogas is a renewable energy resource produced by anaerobic digestion (AD).…”

In 2014-2015, there was approximately 26,823.44 x106 kg of the residue leftover from agricultural products in Northern Thailand and roughly 18,943.57x106 kg or 70.62% were left unutilized. The aim of this research was to survey and calculate the proportion of agricultural area and products as well as their corresponding waste towards potential of biogas production using biochemical methane potential (BMP) method. The results showed that rice straw was the most promising feedstock for methane production with the highest biogas yield of 363 mlN /gVSadded followed by sugarcane leaves and corn cob having 333 and 318 mlN/gVSadded, respectively. Additionally, the predicted areas for growing rice and corn decreased. Meanwhile areas for growing cassava, sugarcane and oil palm increase slightly. This study also found out that the unused agricultural waste generation was decreased due to improved waste utilization.
