TLDR
In this article, the authors review past and future trends in sludge handling, focusing mainly at thermal processes (e.g. pyrolysis, wet oxidation, gasification) and the utilization of sewage sludge in cement manufacture as a co-fuel.Abstract:
The European Union has made progress in dealing with municipal wastewater in individual countries and as a corporate entity. However, it intends to make still further and substantial progress over the next 15 years. Currently, the most widely available options in the EU are the agriculture utilization, the waste disposal sites, the land reclamation and restoration, the incineration and other novel uses. The selection of an option on a local basis reflects local or national, cultural, historical, geographical, legal, political and economic circumstances. The degree of flexibility varies from country to country. In any case sludge treatment and disposal should always be considered as an integral part of treatment of wastewater. There is a wide range of other uses for sludge, which exploit its energy or chemical content, namely the thermal processes. The present paper sought to review past and future trends in sludge handling, focusing mainly at thermal processes (e.g. pyrolysis, wet oxidation, gasification) and the utilization of sewage sludge in cement manufacture as a co-fuel.read more

Feasible and effective reuse of municipal sludge for vegetation restoration: physiochemical characteristics and microbial diversity.
TL;DR: Compared to garden soil, the mixed substrate was weakly alkaline, and had higher nutrient contents, which is beneficial for A. altissima, and results in better growth in mixed substrate, and suggests this mixed substrate as a potentially feasible and effective pathway for the reuse and recycling of municipal sludge for vegetation restoration.

Pilot-scale operation of enhanced anaerobic digestion of nutrient-deficient municipal sludge by ultrasonic pretreatment and co-digestion of kitchen garbage
TL;DR: In this paper, a pilot-scale study was carried out to evaluate the in situ anaerobic digestion of nutrient-deficient activated sludge (AS) from southern China, and the performance of ultrasound pretreatment and co-digestion with kitchen garbage was evaluated by comparing volatile solids removal and biogas production.

Assessment of co-composting of sludge and woodchips in the perspective of environmental impacts (EASETECH).
TL;DR: To reveal potential impacts to environment and human health quantitatively, co-composting and utilization of sludge and woodchips were investigated using a life-cycle-based model, EASETECH and offer evidence for appropriate sludge treatment selection.

Correlation between heating values and thermogravimetric data of sewage sludge, herbaceous crops and wood samples
TL;DR: In this paper, the thermal properties of a sewage sludge sample, woody (black locust, poplar and willow) and herbaceous (energy grass and wheat straw) biomass as well as mixed (sewage sludge and black locust in ratios 1:1 and 1:3) samples were compared under inert and oxidative atmosphere.

Sequential extraction procedure for the speciation of particulate trace metals
TL;DR: In this paper, an analytical procedure involving sequential chemicai extractions was developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions: exchangeable, bound to carbonates, binding to Fe-Mn oxides and bound to organic matter.

Trace metal analysis on polluted sediments
Ulrich Förstner,Wim Salomons +1 more
TL;DR: In this article, the authors proposed a standardization with respect to grain size effects, commonly achieved by analyzing the sieve fraction <63μm, which is used to pin point major sources of metal pollution and to estimate the toxicity potential of dredged materials.
