Chemical engineering research encompasses a plethora of subjects ranging from nanoscale to climate change, from medicine to hazardous waste management, and from electronics and photonics to process intensification, manufacturing, and modelling. The 2017 AIChE meeting included 8000 oral presentations and posters with all these diverse topics. Here we identify experimental methods and instrumentation that straddle these subjects based on Can. J. Chem. Eng. articles published from 2016–2017. Temperature, pH, pressure, and flow rate are the physical properties most researchers report. We identified over 50 experimental techniques, reactor types, and modelling methodologies and show that articles with an experimental focus are more strongly linked than those that concentrate on hydrodynamic modelling and numerical simulation. Spectroscopy dominates instrumental techniques to characterize solids and catalyst properties and we classify 36 instruments according to what property they measure and the scale, nature of the phase, composition, and morphology. A bibliometric analysis grouped the physicochemical properties into three major research clusters centered around solid properties, liquid phase properties, and gas phase and aqueous phase properties. Articles in this special series describe the basic principles of one experimental method or instrument that appears frequently in the journal. Together with a short background, the articles highlight fields of application, assess the sources of error, detection thresholds, and uncertainty. This series provides chemical engineers with a concise, accessible reference guide to help identify and choose appropriate experimental techniques and instruments.

“…The recirculation of the leachate component during co-composting is also found to provide added advantages such as maintaining the essential nutrients ratio and reducing the issues of seepage and foul odour (Chen et At this point, it is important to realize that the prevailing biogeochemical transformations of the bio-fertilizer in the soil depends largely on the composition and characteristics of the composting materials, especially the sewage sludge, due to the supplementing of essential nutrients and favourable species of micro-organisms (García-Ocampo 2012; Valdez et al 2020). The organic fraction of composts mainly consists of the functional groups of phenolic, alcoholic hydroxyls and carboxylic acids while the inorganic fraction consists of chlorides and hydroxides (Milojkovic et al 2014;López-Sotelo et al 2017). By virtue of surface-active phenomena, composts are the favourable bio-sorbents to attenuate many toxic substances such as heavy metals and excess nutrients when it is mixed with suitable bulking agents (Balaganesh et Karthick et al 2020).…”

The methods of compost preparation from sewage sludge and their modes of application to the agricultural elds have profound impacts on the soil ecology and environment. Besides their chemical conditioning effect on soil organic matter, they also impart physical attributes to the soil texture and structure. Though it is expected that compost addition improves water holding capacity and nutrient sequestration, there is lack of clarity in correlating the outcomes with conditions of excess nutrient storage/leaching despite the bene ts on crop yield. In this study, we present a systematic cause-evidence-impact relationship on the feedstock, processing and applications of co-composted organic matter. Various analytical tools were compared to elucidate the unique characteristics of co-composted sewage sludge to get a realistic understanding of the complex soil-compost interactions. Results from the spectroscopic characterization reveal the implications of selection of bulking agents and sludge pre-treatment in determination of the nal quality of the compost. The results attribute signi cant parent material in uence to the formation of well-de ned porous structures. The impacts of compost quality on the soil and crop can be proactively determined in terms of elemental composition, functional groups and stability indices. Thus the present approach provides good scope for customizing compost preparations and applications to get the preferred eld outputs.
