wood plastic composites were made with paper mill sludge produced by three different pulping processes. the effects of primary and secondary sludge on composites properties were assessed. higher cellulose content improved the composite properties.
from paper-mill sludge to plastic decking : plastics technology kadent composites president jonathan painter left and v.p. of r and d anatole klyosov are part of the entrepreneurial team turning paper sludge into hdpe composite decking.
the aim of this study was to evaluate some physical and mechanical properties of the paper mill pms and spruce planer shaving added cement boards. also the effect of sludge type in consequence of waste water treatment technique on properties of wood-cement boards wcb was investigated.
we used paper mill sludge pms to substitute for part of the wood fibers wf used to reinforce high density polyethylene hdpe . the resulting composites were subjected to xenon-arc weathering. the composite filled with limited pms under 10 % had mechanical properties and aging resistance similar to those without pms.
from paper-mill sludge to plastic decking. link/page citation * kadant composites' self-appointed mission for the past eight years has been to find commercial uses for paper sludge, a soggy mix of short cellulose fibers, calcium carbonate, and clay that is the copious byproduct of paper recycling. the idea was for fibergen to build a plant
pulp and paper sludge can be recycled in the manufacture of medium-density fiberboard mdf because it contains wood fibers. a comparative study was conducted to evaluate the properties of mdf made from virgin fibers mixed with different pulp and paper sludge sources.

paper mill sludge pms is a waste material from pulping. in this article it was used to replace part of a wood fiber wf filler to reinforce highdensity polyethylene hdpe . the properties of the pms/wf/hdpe composites were investigated.
the disposal of paper mill sludge pms is a difficult environmental problem. thus, pms has been used as a substitute for wood fiber wf to reinforce highdensity polyethylene hdpe . in this study, we compared pms wf hdpe composites with composites without pms after water immersion and thermal treatment.
protein extraction from secondary sludge of paper mill wastewater and its utilization as a wood adhesive. muhammad pervaiz a, * and mohini sain a. in this study, secondary sludge ss from a kraft paper mill was used as a source of biomass to recover protein and investigate its potential use as a wood adhesive.
the wood pellets were produced from saw dust pine by ab svensk brikettenergi. the sludges originated fromresults wastewater treatment plants of five swedish pulp and paper mills. the sludge consists mainly of three fractions: pure fibre sludge, sludge produced by chemical precipitation or by apredried pulp and paper sludge
characteristics of paper mill sludge and its utilization resource for wood fiber-based composite panels. fiberboard panels are one of the most commonly used furniture and building materials, and the consumer demand for fiberboard panels has been increasing over the years.
a comparative study was conducted using paper mill sludge from three different pulping processes at two primary sludge ps to secondary sludge ss ratios to better understand the role of ps and ss in the development of wood/high-density polyethylene hdpe composite properties. sludge samples from
