2016/2/18/ · The main objectives of this study were to investigate the compostability of wastewater treatment sludge (WTS) containing different bulking agents (BAs) and to determine the most efficient BA. Four different compost trials consisting of mixtures of wheat straw (WS), plane leaf (PL), corncob (CC) and sunflower stalk (SS) with WTS were

2015/9/15/ · An emergy analysis to evaluate the synergic reduction effect of urban sewage sludge use as alternative raw material or fuel in clinker production was carried out. The main steps of the synergic treatment process, namely (1) sewage sludge treatment and (2) its transport to clinker production, were assessed by means of the emergy accounting

2018/2/2/ · The objective of this study was to examine the feasibility of sewage sludge composting using a simple aeration method. Two consecutive composting trials (run A and run B) using Japanese sludge and woodchips (1:1, v/v) were conducted in cubic boxes (0.45 × 0.45 × 0.45 m3) made by plywood at Okayama University. Air was forced up

2020/11/1/ · 1. Introduction. Waste activated sludge (WAS) is the solid waste produced during the biological treatment of wastewater (Wei et al., 2020), especially from municipal wastewater treatment plants (WWTPs).In China, the continuous construction of sewage drainage systems and wastewater treatment facilities has resulted in an increase in the

2023/9/1/ · Settled sludge from sludge treatment ponds has also been used to ‘mix’ compost from solid waste, as shown in Accra, Ghana; farmers in Ghana, Mali, and Benin have been known to bribe septic truck drivers to deposit fecal matter in their fields [50]. The most critical aspect is the SS quality, as it will influence the stabilization procedure

2023/11/30/ · The world is faced with a growing population, increasing pollution, and diminishing resources. As such, there is a growing need to explore the possibility of harnessing resources such as energy from unconventional sources to promote sustainability. Wastewater sludge is a critical point to recover energy in the form of both gas and

2022/12/5/ · Modern compost machines are the gateway to a circular economy as it relates to food waste and other compostable material. This decentralized approach to waste management eliminates waste hauling, renders landfills useless, and generates a valuable commodity, compost. Let’s get started. The chemistry of composting: Aerobic

2020/12/22/ · Conventional fertilization practices in agroecosystems concern the supply of bioavailable nutrients, such as mineral fertilizers. A consolidated alternative to restoring the long-term fertility of agricultural soils is their amendment with organic fertilizers. Soil amendment with biowaste compost or sewage sludge represents a sustainable strategy

2002/9/12/ · The advantages of using biosolids are part of your fertilizer program are many. The greatest advantage is a reduction in fertilizer costs. In Georgia, the Environmental Protection Division's "Guidelines for Land Application of Sewage Sludge (Biosolids) at Agronomic Rates" requires the soil pH to be maintained at 6.5 or above.
