Chromated copper arsenate (CCA)-treated wood was liquefied with polyethylene glycol/glycerin and sulfuric acid. After liquefaction, most CCA metals (98% As, 92% Cr, and 83% Cu) were removed from liquefied CCA-treated wood by precipitation with calcium hydroxide. The original CCA-treated wood and liquefied CCA-treated wood sludge were fractionated by a modified Community Bureau of Reference (BCR...

Omni Processors (OP) are machines which use sludge as a fuel to generate electricity and clean water, but create ash at the same time. In present study, fly bottom investigated materials for potential reuse in construction field. First, granular size, density Blaine finesse determined. Then, chemical composition microstructure obtained by means of X-ray fluorescence Scanning Electron Microscopy...

Developing efficient, low-cost, and stable carbon-based catalysts for oxygen reduction reaction (ORR) to replace the expensive platinum-based electrocatalysts remains a major challenge that hamper the practical application of fuel cells. Here, we report that N, Fe, and S co-doped nanoporous carbon material, derived via a facile one-step pyrolysis of sewage sludge, the major byproduct of wastewa...

Due to the fact that compost is a valuable fertilizer serves principally as source of macronutrients, composting one preferred methods management organic waste, including municipal sewage sludge. However, due its high moisture content and low C/N ratio, sludge cannot be composted alone. This study investigated usefulness waste willow-bark (WWB) (after salicylate extraction) an amendment for sew...

Abstract As the significant residuals in sewage treatment system, sludge and reuse play a pivotal impact on environmental sustainability study China. In this paper, two systems have been investigated, calculated, analyzed, including conventional system (Scenario A) improved B), respectively. The results demonstrate that (1) Compared to Scenario A, B is comprehensive which integrates brick produ...
