The recovery of degraded areas is imperative for the sustainability mining activities. main action implemented to improve chemical, physical and biological conditions soils, tailings sterile deposits incorporation organic material. Biosolids (hygienized sewage sludge) are among materials that can be applied. However, considering health risk they represent, not all suitable receiving this waste....

A three-year field study was conducted to evaluate the impact of two different agro-industrial byproducts on soil properties, provisioning services, olive quality and production in a traditional rainfed grove assess suitable management options for recycling organic wastes reduce use inorganic fertilizers. The amendments consisted compost (AC), made from residues oil industry (“alperujo”), bioso...

Deteriorating soil fertility and gradually decreasing rice productivity along with higher greenhouse gas emissions from paddy fields have emerged as serious threats to the sustainability of production food security. Rice in subtropical environment Bangladesh is mostly dependent on synthetic inorganic fertilizer maintain productivity; however, has negative effects global warming. Climate-smart r...

Simple and suitable treatment of swine slurry from small farms is paramount especially in sensitive areas. This paper evaluates the viability an innovative nature-based technology hybrid system (a Vertical Flow Constructed Wetland followed by a Horizontal both planted with reeds – Phragmites australis ) to treat for further land application or discharge water bodies reduced nitrogen impact. Phy...

Abstract Corn was grown under greenhouse conditions in the presence of uncleaned versus cleaned municipal sewage sludge to assess effectiveness a chemical leaching process that uses an inorganic acid and strong oxidants clean biosolids (i.e., remove metals without reducing their agronomic potential). Specifically, our study analyzed physicochemical from Montreal (MSL) wastewater treatment plant...

Ferric oxide-containing waterworks sludge can be used to reduce the formation of hydrogen sulfide during anaerobic digestion. The ferric compound is reduced biochemically in digester and forms insoluble pyrite sludge. Virgin chloride often solve problem. Since 2013, Sydvatten AB has supplied a growing number digestion plants Sweden with ferric-containing dewatered derived from drinking water tr...

● Content of heavy metals in hydrochar varies considerably, from 50% to 100%. Concentrations can be higher than those the dairy manure. are far below regulatory level. Hydrochar produced manure is a regulated biosolid if being promoted for agricultural applications thus must have properties that comply wit...

This study evaluated the influence of 20 annual land applications of Class B biosolids on the soil microbial community. The potential benefits and hazards of land application were evaluated by analysis of surface soil samples collected following the 20th land application of biosolids. The study was initiated in 1986 at the University of Arizona Marana Agricultural Center, 21 miles north of Tucs...

BACKGROUND Bioelectrochemical systems have been considered a promising novel technology that shows an enhanced energy recovery, as well as generation of value-added products. A number of recent studies suggested that an enhancement of carbon conversion and biogas production can be achieved in an integrated system of microbial electrolysis cell (MEC) and anaerobic digestion (AD) for waste activa...
