Flame retardants (FRs) play an important role as additives which is applied in a wide range of products because they can inhibit ignition to delay the spread of fire. By adding fly ash (a waste of thermal power plants), we have developed an epoxy resin material with good flame retardant properties. Besides, using the fly ash can reduce the consumption of current flame retardants (organic halogen compounds) and thus meet the environmental safety of flame retardant epoxy resin.

The building sector has negatively impacted on environment and people health due to high consumption of energy as well as significant emission of CO2 from material production and large consumption of nonrenewable raw materials. It is therefore necessary to develop new products that not only satisfy the same technical criteria, but also have enhanced qualities in term of the environment, people health and comfort.

The eco-efficiency indicator is recognized as an effective tool to measure sustainability in construction. This study proposes s indicators to measure eco-efficiency at project and component levels during the roadway life cycle. Conventional cost over energy consumption and conventional cost over GHG emissions are two most prominent indicators in the material production stage, whereas conventional cost over solid waste is the most prominent in the disposal/recycling stage.

In the attempt to support the development of sustainable transport in Vietnam, this study investigates the material stocks of road and railroad network. A long-term preference for transport development (especially road and railroads network) has led to approximately 40% of Vietnam’s annual consumption of construction materials to be for expanding and maintaining its network, causing stress on natural resources and the environment.

Disposable/ Single-use plastic has become more prevalent in production and consumption than other materials due to the advantages it may bring. However, wastes from SUP, especially plastic packages, account for nearly half of the global plastic wastes, causing potential environmental problems. Students are not only a big group but also an influential group in the process of reducing SUP in Vietnam.

This research shed some light on green consumption behavior of consumers in Vietnam. Materialism (centrality), environmental concern, perceived risk and trust were all reported denoting significant influence on consumers’ willingness to purchase green products in Vietnam. Limitations for this study mainly come from the representativeness of the sample, which was restricted to consumers in Hanoi. This paper provides a conceptual framework to explain green consumption and its motives.

Tomato is one of the most important vegetables cultivated in Vietnam. Besides its regular consumption as a vegetable, a new demand for using tomato as a decorative plant on special occasions was identified in recent years. This study aimed to characterize new tomato accessions on their desirable morphological traits to select potential materials for further breeding programs of ornamental tomato varieties in Vietnam.

Particle size is important parameter affecting the composition, quality and final applications of the producer gas. Fine grained or fluffy feed stock may cause flow problems in the gasifier as well as an inadmissible pressure drop over the reduction zone and a high proportion of dust in the gas. To avoid such problems briquetted material considered for gasification. The developed gasifier was tested with different sizes of briquettes of 15, 30 and 45 mm width and 90 mm diameter. The volatile matter, fixed carbon and ash content of briquette were found as 71.87%, 17.07% and 4.
