The purpose of the study on the association between factors affecting environmental information disclosure quality of listed companies in the Stock Exchange of Thailand was to investigate factors which posed impacts on the listed companies in Thailand Stock Exchange using the information from 2007 to 2011. The data applied Multiple Regression Analysis to test the relationship between the dependent variable environmental information disclosure quality and independent variable which included the ability to compete the ability to make profits business liquidity operation period business industry and business size as control variables. The result showed that the ability to compete was significantly related to the quality of the environmental information disclosure. This means that the higher competition the more environmental information disclosure. Regarding the other variables such as the ability to make profits business liquidity and operation period did significantly not relate to the environmental information disclosure quality. Moreover business size had significant positive association with the quality of the environmental information disclosure which means that bigger businesses are more capable to reveal their environmental information than the smaller ones. The information disclosure qualities in terms of resources legalization and sustainability were reported more highly than others. However the companies producing industrial products disclosed their companies’ policies more while service industries revealed more about their accounting and financial information which related to the environment.

The purpose of the study was to scrutinize patterns and levels of environmental accounting disclosure of listed companies in eight industries in the Stock Exchange of Thailand. The research applied documentary research methodology and descriptive statistics including percentage distribution and Correlation analysis using Chi – Square at Statistical significance at the 0.05 level. The results of the study showed that five among eight industries including agro- and food industry consumer goods industry industrial goods industry real estate and construction industry and resources industry disclosed their environmental accountings at level 2; specific but not quantitatively measurable. However each company paid the highest attention to the environmental management systems because of its prominent requirements. As for the other three industries which were finance industry service industry and technology industry disclosed their environmental accountings at level 0; no environmental accountings disclosure since they paid limited interest to the environmental accounting during 2009 and 2012. In terms of the relationship between the entrepreneur and the environmental accounting disclosure it was found that the entrepreneur’s five aspects such as the business operational period paid paid-up registered capital total assets total liabilities and total revenues were significantly related at the disclosed level of 0-3.

The study was aimed to investigate environmental conservation conscience and related knowledge of Business Administration undergraduates at Rajamangala University of Technology Phra Nakhon. It was also intended to examine the relationship between the environmental conservation knowledge and the students’ environmental conservation conscience. The samples were 208 fourth year students studying in the second semester of at the Faculty of Business Administration in 2013. The data were collected through the questionnaire regarding the environmental conservation conscience and related knowledge and were analyzed by the frequency distribution percentage distribution standard deviation t-test and One – Way ANOVA. In case of 0.05 statistical differences was found Scheffe’s method was applied for adjusting significance levels in a linear regression analysis to account for multiple comparisons as well as Pearson Product Moment Correlation statistically significant at 0.05 level. The result showed that Business Administration undergraduates highly displayed their environmental conservation conscience and related knowledge and moderately related (r = 0.407) and statistically significant at level of 0.05.

The using of ground coffee wastes from industries to develop the cement board is an objective of this research that can solve the air pollution problems from smell and spreading of ground coffee wastes. The ratio of Portland cement type1: fine sand: tap water is equal to 1: 0.5: 0.416 by weight and the ratios of Portland cement type1: ground coffee wastes include 1: 0.05 1: 0.06 1: 0.07 1: 0.08 1:0.09 and 1: 0.10 by weight (6 ratios). The production of cement board uses the pressure casting in temperature 30 – 35 degree of Celsius and controls 0.75 g/cm3 of density. The testing of cement-bonded fiberboard properties follow the TIS 878-2537 standard (cement bonded particle board: high density). From the results 1: 0.05 is the most suitable quantity of cement: ground coffee wastes which mixed in cement board. This cement boards can reduce the ground coffee wastes by using as aggregate to produce the construction materials.

This research aims to develop the cement board from coconut shell ash. The Portland cement type1: fine sand: tap water ratio is equal to 1: 0.4: 0.33 by weight. The 5 ratios of Portland cement type1: coconut shell ash include 1: 0.12 1: 0.13 1: 0.14 1: 0.15 and 1: 0.16 by weight. The cement board production uses the pressure casting in normal temperature (30 – 35 degree of Celsius) and controls the 0.75 g/cm3 of density then test the properties of cement-bonded fiberboard follow TIS 878-2537 standard (cement bonded particle board: high density). From the results 1: 0.12 is the most suitable ratio of cement board from coconut shell ash. This developed cement boards can reduce the quantity of coconut shell ash waste and have the good thermal insulation.
