This work aimed to reveal the differences of nitrogen (N) transformation between animal-derived and plant-derived biochar during paper mill sludge composting. Three treatments were established, including CK (no biochar), ABC (animal-derived biochar), and PBC (plant-derived biochar). Results showed t
2017/4/1/ · Primary Paper mill sludge (PMS), cow dung and sawdust were mixed in five different ratios for preparing the feed material for rotary drum composting. PMS was collected from Nagaon Paper Mill, a unit of Hindustan Paper Corporation situated at Nagaon in the state of Assam, India at a distance of around 70 km from Indian Institute of
the inoculated compost at the certain stages of the composting process. It was recommended to use thermophilic bacteria as a start inoculum to improve the PPMS composting process. Keywords: thermophilic bacteria, pulp and paper mill sludge, DGGE, API ZYM 1. INTRODUCTION Pulp and paper mill sludge (PPMS) is the main organic residual
2013/12/1/ · A potential raw material for the production of compost may be the waste from paper production—pulp and paper mill sludge [18,19,20]. Waste from the pulp and
In this study, the roles of AL and SLS additives in the formation of humic substances (HS) during paper mill sludge composting were investigated. Results showed that HS content and degree of polymerization of the final products in AL (44.42 mg·g -1 and 0.70, respectively) and SLS (45.87 mg·g -1 and 1.14, respectively) treatments were
Co-composting dewatered paper mill sludge (PMS) and hardwood sawdust, two readily available materials in Canada, was investigated using uncontrolled and controlled In tank processes. The composted materials were characterized for total C and N, water-soluble, acid-hydrolyzable, and non-hydrolyzable N, extractable lipids, and by Fourier
The compost mass contained 18% (DW) of pulp and paper mill sludge, 40% DW of fruit-vegetable waste, 32% DW of Agronomy 2022, 12, 13 4 of 18 spent mushroom substrate, and 10% DW of rye straw. Each 100 kg of its fresh weight (FW) included 20 kg FW of pulp and paper mill sludge, 54 kg FW of fruit-vegetable waste, 22 kg FW of spent mushroom
Co-composting dewatered paper mill sludge (PMS) and hardwood sawdust, two readily available materials in Canada, was investigated using uncontrolled and controlled In tank processes. The composted materials were characterized for total C and N, water-soluble, acid-hydrolyzable, and non-hydrolyzable N, extractable lipids, and by Fourier
Conclusions The physicochemical and phytotoxicity changes during the reactor composting of OFMSW, paper & pulp mill sludge and sawdust have been investigated at initial mix ratios of 1:3, 1:6 and 1:9. The final characteristics indicate the stability and usability of the compost in all the reactors with paper & pulp mill sludge.
Pulp and paper mill sludges (PMS) are a significant byproduct of the paper making industry world-wide, and composting with mineral nutrients in Tasmania is viewed as the most environmentally suitable method to convert this material into a horticultural product, thus eliminating the need for landfilling. The major control variables for composting PMS with a
All the prepared compost samples sub-samples and sample of paper mill sludge before composting were taken, air dried and sieved through 2 mm sieved and extracts were processed for physico-chemical

2004/2/1/ · Moreover earlier studies of invessel composting of paper mill sludge required long time for the composting process and varied between 121 days to 28 days (Jackson and Line, 1997;Das et al., 2001).
2002/11/1/ · Use of organic by-products as soil amendments in agricultural production exemplifies a strategy for converting wastes to resources. The overall objective of this research was to evaluate the short- and intermediate-term effects of repeatedly amending sandy soil with paper mill residuals (PMR) and composted PMR in a vegetable rotation in
2. Trends in paper mill sludge generation The pulp and paper industry produce over 304 m illion tons of paper per year. In 2005, soley in Europe, 99.3 million tons of paper was produced which generated 11 million tons of waste and represented 11 % residue in relationship to the total paper production. The
