In this study, experimental results on mesoporous zeolite preparation from a common solid waste, the rice husk ash by a top-down and bottom-up approach were reported. In top-down method, the consecutive treatments of zeolite by acid and alkaline in the presence of a cationic surfactant (CTAB) successfully generated mesopores in the zeolite.

A series of Mg-Cu-Al hydrotalcite/chitosan materials have been synthesized via a co-precipitation method, in which chitosan is synthesized from chitin extraction from waste shrimp shells. The obtained solids were characterized by XRD, BET, EDX, IR techniques. The materials have a well crystallized hydrotalcite structure and medium surface area.

The increase in solid waste volume and change in composition due to urban development cause negative effects on the marine ecological environment. The aim of this study was to assess the amount of plastic waste leaking into the environment from the municipal solid waste (MSW) management system and propose mitigation measures towards sustainable development in Hue city, Viet Nam.

The microstructure of the LFC was also examined using the scanning electron microscopy (SEM) technique. Furthermore, the results of the present study encourage the reuse of industrial by-products in the production of sustainable construction materials and thus can be considered as a potential solution for industrial solid wastes treatment.

In this study, we investigate using acrylic and acrylic-styrene emulsions as curing solution to enhance water resistance and prevent cracking in cement concrete surfaces. Our main objective is to investigate the possibilities of utilizing washing waste generated during the Rhomn & Haas factory - Dow Chemical Vietnam production process. This waste is currently being treated as solid even though it contains anywhere from 10 – 45 % solid content.

Wastes generated from healthcare practices are a serious problem for humans as well as for the environment. In this study, an attempt was made to use mixed solid medical waste (WPN) which consisted of shredded waste plastic and chopped waste needles for partial replacement of natural fine aggregate (sand) in concrete mixes at 0%, 2%, 4%, 6%, 8% and 10% by weight.

The amount of waste generated is increasing in both quantity and complexity, in line with the level of economic development, but the land area available for solid waste treatment is limited. Residents' attitudes and willingness to pay (WTP) regarding waste segregation at source and recycling were investigated in this study through a survey using questionnaires conducted in the Hiep Hoa district, Bac Giang province.

The aim of this study is to enhance biogas production from the organic fraction of municipal solid waste (OFMSW) and garden waste (GW) via pretreatment and codigestion. In order to achieve the aims of the study, two objectives have been developed and are outlined below: To investigate an optimum co-digestion mixture of OFMSW with untreated and pretreated GW; to investigate the effectiveness of different pretreatments on the potential for biogas production from GW and to identify the relationship between certain changes in GW characteristics and enhanced yield.

Poultry industry is one of the fastest growing markets. The poultry industry produces large amounts of solid waste. There are many different waste management options for poultry waste including land application of litter as an organic fertilizer, feed for livestock, biogas production, products for commercial purposes. Poultry wastes are posing serious environmental pollution problems, through offensive odours and promotion of fly and rodent breeding. The appropriate utilization of its waste or by-products increases the monetary output and protects from its unwanted side-effects.

This research was carried out to evaluate the effect of organic loading rate to the performance of anaerobic co-digestion digester treating organic fraction of food waste (FW) and sludge waste (SW) from wastewater treatment plant. The experiment was conducted in two runs: Run S50, substrate contained 50 % of FW and 50 % of SW in term of volatile solid (VS) concentration; Run S100 (control run) contained 100 % SW in the influent substrate.
