This research studied recycled waste by the Recyclable Material Bank Project of 4 universities in the central region of Thailand for the evaluation of reducing greenhouse gas emissions compared with landfilling activity during July 2012 to June 2013. The results showed that the projects collected total amount of recyclable wastes of about 911,984.80 kilograms. Office paper had the largest amoun...

Many asphalt pavements fail structurally after having performed well for some years. In China, when low volume of traffic highway is recycled, the surface course and base stabilized by inorganic stabilizers are sometimes recycled mixed together to form a new base. Portland cement, lime-fly ash, lime or cement-fly ash added improve strength base, but they not used at same time, so it difficult r...

Organic sticky contaminants represent one of the biggest technical challenges in paper recycling process. These reduce strength, cause plugging wires and felts, stick to or deposit on machine parts affecting runnability machine. The removal these is difficult achieve along process due heterogeneous nature organic contaminants. In this study, multiple wastepaper grades was analyzed characterized...

The efficient use of papermaking potential secondary fiber by gentle refining recycled pulp is one the basic principles for recovered paper stock preparation. mild modes more important in case wetstrength than conventional waste paper. This due to fact that weakened hard conditions wet-strength repulping, particular, long repulping time, elevated temperature, alkali and oxidizers. study aims at...
