organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. an integrated approach of composting methodology was tested for municipal solid waste management. solid waste first was composted and after 22 days, was...

Since potassium is essential for plant nutrition, should this element be deficient in sewage sludge used for plant fertilization supplementary mineral potassium fertilization is necessary. The aim of the present study has been to evaluate the effect of fertilization with organic materials on maize yield, its potassium concentrations and the content of bioavailable forms of potassium in soil of ...

Sustainable agriculture practices within the guidelines of nutrient recycling and circular economy must be increasingly promoted. This work aims to evaluate performance dried sewage sludge (DSS), green liquor dregs mixed with (DSSA), raw sludge, commercial organic fertilizer control, using a short-term agronomic assessment lettuce crop (Lactuca sativa) in greenhouse conditions. Different applic...

Microplastics were investigated in an agricultural soil to which three types of sludge repeatedly applied: fresh municipal (FSS1), mixed (mainly industrial sludge) (FSS2), and dry heat-treated (DSS). The percentages microplastics <1.0 mm 24.3 28.7–59.1 % unamended amended soils, respectively. Particles this size accounted for 47.1–60.0 different sludges polymers particle <100 μm occurred all sa...

Introduction: Nitrophenol compounds are toxic compounds found in industrial wastewaters. 2,4-dinitrophenol is the most dangerous compound among phenolic compounds. The aim of this study was to evaluate the removal of 2,4-DNP from wastewater by microwaved dried sludge adsorbent. Materials and Methods: The results of 2,4-DNP removal were discontinuously obtained by the high performance liquid ch...

Sludge incineration is a sludge resource management and disposal method that can greatly decrease the volume of sludge, reduce degree harm realize recovery heat energy. Most research on focuses combustion process gas emissions, but there are relatively few studies fuel molding drying before incineration. Besides, independent has high energy consumption. This paper proposes pre-incineration trea...

Over a 3-yr period 336 MT/ha of dried sewage sludge, from a municipal waste treatment plant, was applied in liquid form to land subsequently used to grow corn. The sludge contained 115 mg Cd, 4,200 mg Zn and 538 mg Ni/kg dry matter and comprised the solids remaining after treatment of the waste waters of approximately 260 industries as well as domestic users. Corn grain harvested from the plot ...

Digested sludge (DS) is a waste product of anaerobic digestion that produced during the biodegradation excess sludge. It cannot be used as substrate for further biogas production owing to its recalcitrant nature. In present study, we heat treatment technique convert DABYS microflora (DABYS = digested sludge-assimilating and biogas-yielding soil microflora), which degraded DS methane gas, could ...
