The behavior of rPUf (polyurethane foam derived from bis(2-hydroxyethyl) terephthalate (BHET)recovered from post-consumer poly(ethylene terephthalate)-PET bottles) and cPUf (polyurethane foambased on a commercial polyol) were evaluated by comprehensive characterizations, and their thermalstabilities,flammabilities, and physical properties were compared. Without using aflame retardant, rPUfpassed the UL-94HB standard, whereas cPUf burned rapidly to the holding clamp. Various formulationsof rPUf and cPUf with established eco-friendlyfire retardants (FRs), including triphenyl phosphate,aluminum diethylphosphinate, and aluminum trihydroxide, exhibited notably higherfire resistance. Thedifferences between the experimental and calculated densities showed the effectiveness of the foamingprocess. A larger difference indicated that the FR improved the foaming process more. The BHET structurecontains an aromatic moiety that strongly enhanced the compressive strength and protected the rPUf/FRsfrom biodegradation, as evidenced by sorption isotherm experiments. For that reason, the rPUf/FRs couldbe used as building materials, especially under high humidity conditions. These are the advantages ofBHET over the commercial polyol for PUf preparation. Chemical recycle of post-consumer PET bottles toproduce high performance PUf could be applied on an industrial scale and then it creates the sustainablerecycling industry.

In recent years, there has been a substantial theoretical and empirical study on the role that financial market development has significantly played in promoting economic growth and development in the world. The development of an economy requires the financial industry to be developed. In the context of rapid economic development, global warming has become a serious problem with issues such as rising average temperatures, climate change, rising sea level, and increasing carbon dioxide emissions. This study aims to examine the influence of economic growth, financial development, transportation capacity, and environmental degradation. Using time-series data from 1986 to 2019 and environmental degradation being measured by CO2 emissions, the study employs a quantity of ample unit root tests, the structural break unit root tests, Autoregressive Distributed Lag (ARDL), and cointegration bounds test. The results show that there is a significant long-term cointegration among study variables. Empirical findings also indicate that an increase in per capita GDP and financial development worsens environmental quality whereas transportation capacity and foreign investment can improve environmental quality.

In Vietnam, the WHO Framework Convention on Tobacco Control (WHO FCTC) took effect in March 2005 while MPOWER has been implemented since 2008. This paper describes the progress and challenges of implementation of the MPOWER package in Vietnam. We can report that, in term of monitoring, Vietnam is very active in the Global Tobacco Surveillance System, completing two rounds of the Global Adult Tobacco Survey (GATS) and three rounds of the Global Youth Tobacco Survey (GYTS). To protect people from tobacco smoke, Vietnam has issued and enforced a law requiring comprehensive smoking bans at workplaces and public places since 2013. Tobacco advertising and promotion are also prohibited with the exception of points of sale displays of tobacco products. Violations come in the form of promotion girls, corporate social responsibility activities from tobacco manufacturers and packages displayed by retail vendors. Vietnam is one of the 77 countries that require pictorial health warnings to be printed on cigarette packages to warn about the danger of tobacco and the warnings have been implemented effectively. Cigarette tax is 70% of factory price which is equal to less than 45% of retail price and much lower than the recommendation of WHO. However, Vietnam is one of the very few countries that require manufacturers and importers to make "compulsory contributions" at 1-2% of the factory price of cigarettes sold in Vietnam for the establishment of a Tobacco Control Fund (TCF). The TCF is being operated well. In 2015, 67 units of 63 provinces/cities, 22 ministries and political-social organizations and 6 hospitals received funding from TCF to implement a wide range of tobacco control activities. Cessation services have been starting with a a toll-free quit-line but need to be further strengthened. In conclusion, Vietnam has constantly put efforts into the tobacco control field with high commitment from the government, scientists and activists. Though several remarkable achievements have been gained, many challenges remain. To overcome those challenges, implementation strategies that take into account the contextual factors and social determinants of tobacco use in Vietnam are needed.
