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...

Abstract This paper studies the use of wastepaper sludge ash (WPSA) for structural concrete in binary and ternary mixes with high-strength cement two industrial by-products, ground granulated blast-furnace slag (GGBS) pulverised fuel (PFA). The potential WPSA this type its combination other supplementary cementitious materials has not been established; thus, further research is needed prior to ...

The evolution of the microstructure wastepaper sludge ash-based dry-mortar mixtures is characterized. Mixtures have been prepared with a large volume ash (WSA) and ground granulated blast-furnace slag (GGBS) as binder matrix mixed water. Two ratios water/binder (w/b) = 0.5 0.6 were selected. Both these two industrial by-products are well-known supplementary cementitious materials in constructio...

Kitchen Lemongrass (Cymbopogon Citratus) waste has the potential to become a strong and environmentally-friendly material for handmade paper due its high cellulose content, distinctive texture aroma. So far, made from kitchen lemongrass is in Thailand India available international market. Indonesia, which quite resources, not explored much exploration of paper. Although it good as material, mus...

The last two decades have seen a constantly increasing interest in mindfulness, due to its positive effects on health and well-being. Recently, a number of mobile applications aimed at supporting people in practicing mindfulness techniques have appeared, but their efficacy has not been formally evaluated yet. In this paper, we first introduce the reader to mindfulness techniques, traditional as...
