Chlorine-free extraction and structural characterization of cellulose nanofibers from waste husk of millet (Pennisetum glaucum)
PublikacjaThis study aims to extract cellulose nanofibers (CNFs) from a sustainable source, i.e. millet husk, which is an agro-waste worthy of consideration. Pre-treatments such as mercerisation, steam explosion, and peroxide bleaching (chlorine-free) were applied for the removal of non-cellulosic components. The bleached millet husk pulp was subjected to acid hydrolysis (5% oxalic acid) followed by homogenization to extract CNFs. The extracted...

The effect of agro-waste co-digestion and sludge disposal on carbon footprint in municipal wastewater treatment plants
PublikacjaThe study presents analysis of the carbon footprint (CF) in 6 wastewater treatment plants in northern Poland with a special focus on the effect of co digestion of sewage sludge and food waste. Although co-digestion increases the on-site energy production, but it has a negative effect on the total CF. To overcome the negative effect, several sludge disposal scenarios were analysed and their effect on the CF reduction was determined....

Biochemical assays of intensified methane content in biogas from low-temperature processing of waste activated sludge
PublikacjaAnaerobic digestion (AD) is implemented as an important ‘waste to energy’ approach for converting organic-rich byproducts such as sewage sludge into biogas and nutrient-rich digestate. Sewage sludge consists of primary sludge and waste activated sludge (WAS), and low biodegradability of WAS limits methane production. This study presents the influence of the low-temperature pretreatment (LT-PT) of WAS on the efficiency of AD. Different...
