Hydrolysis is the most critical stage in high solids Temperature Phased Anaerobic Digestion (TPAD). In this paper two different Organic Fraction of Municipal Solid Waste (OFMSW) types were tested co-digestion with Digested Sludge (DS) at temperatures: 37, 55 and 65 °C. Volatile fatty acids (VFAs), soluble chemical oxygen demand (CODs) Biochemical Methane Production (BMP) measured calculated aft...

Although biogas has been primarily produced through liquid anaerobic digestion, this method leads to the floating and stratification of fibers non-homogeneous mixing, which can reduce yield. Alternatively, be by solid-state digestion (SS-AD) organic material with a high solid content, such as corn cobs. We investigated co-digestion food waste cobs biomass feedstock for SS-AD in production. meas...

The objective of the present study is to develop anaerobic co-digestion process which satisfies features required achieve sustainable development by adjusting component feedstock and modelling digestion process. Three were proposed for waste treatment that processing capacity, energy production capacity stability. There analyzed from viewpoints mass circulation, biogas yield respectively. devel...

In the context of increasing pressure regarding sustainable utilization food waste in a circular economy, one trends is their biological transformation, through anaerobic digestion, into biogas as renewable source energy. We presented physical-chemical properties main categories from different sources: dairy, meat, and poultry, fish, fruit vegetable, cereal bakery, brewing winery industries, ot...

background: the aim of this study was to determine bioavailability heavy metal concentrations of cu, cd, cr, co and zn and health risk assessment in different types of klang district, selangor (malaysia) urban surface soil using in physiologically based extraction test in vitro human digestion model. methods: a total of 76 urban surface soil was sampled based on seven different types of land us...

identification of exogenous factors affecting spermatogonial stem cells (sscs) proliferation in vitro, provides worthy ways to study the basic biology of the cells. the aim of this study was to investigate the effects of a gnrh analogue (alareline acetate) on sscs colonization in short-term co-culture with sertoli cells. five, three-month old holstein male calves were used to isolate spermatogo...

A mathematical model has recently been proposed by the authors to simulate the biochemical processes that prevail in a co-digestion reactor fed with sewage sludge and the organic fraction of municipal solid waste. This model is based on the Anaerobic Digestion Model no. 1 of the International Water Association, which has been extended to include the co-digestion processes, using surface-based k...

the chemical speciation of heavy metals (arsenic, chromium, copper, lead, zinc and tin) in the sediments offormer tin mining catchment bestari jaya, peninsular malaysia was determined by using the latest version of the community bureau of reference, usually called the bcr 3-step sequential extraction procedure. furthermore, a fourth step was introduced for digestion and analysis of the residue....
