— Slaker grits (SG) and biomass fly ash (BFA), two waste streams generated in the pulp and paper industry, are commonly disposed of in landfills, a practice with a high economic and environmental burden. In this work, their individual valorization as fillers in a commercial screed mortar formulation was evaluated in order to achieve a more …
— Paper mill waste has been obtained from M/s Hindustan Paper Corporation Limited (HPCL), Jagiroad, Assam, India. The lime mud thus obtained from these wastes has been used for making bricks by mixing in different weight proportions with another industrial waste: fly ash; obtained from National Thermal Power Station, Badarpur, Delhi, India.

— A Canadian study assessing the potential of ash residue as an amendment for road construction found considerable benefits in both laboratory and field tests when fly ash from a pulp and paper mill was added at a rate of 10% by weight (Zhou et al., 2000). With this addition rate in the lab tests, the unconfined compressive strength increased ...
In addition, the efficiency of adsorption decreases with increasing adsorption temperature for both fly ash and untreated sepiolite. Keywords: Bleached Kraft Mills Effluent, adsorption, sepiolite, fly ash, phenolic and lignin compounds 1.
