“…Commonly, sludge is used as an addition in the brickmaking process, usually the high temperature firing process. It is reported that the maximum amount of paper mill sludge (PMS) required to be added is 10 wt% because any addition of PMS beyond this weight percentage results in excessively high water absorption values and low compressive strength that do not conform to the standards of conventional bricks . In addition, firing at 900 °C provides improved durability of bricks .…”

Sludge is regarded as a potential source to achieve valorization via strategies such as resource recovery, sludge based adsorbents preparation, bioflucculants production, sludge manufacturing construction materials preparation, sludge composting and thermal valorization, which are currently common and effective strategies. Appropriate treatment strategies of sludge are of great importance worldwide for the fast growing population and rapidly increasing waste. This mini review summarized some widely used and effective strategies to achieve sludge valorization based on whether the strategy would utilize or reuse the potential of sludge to obtain valuable product and eliminate secondary pollution. Anaerobic digestion of sludge is perceived as a potentially cost‐effective method to achieve sludge reduction and resource recovery including carbon, nitrogen, phosphorus resource recovery coupled with other technologies. Utilizing sludge as raw material for preparation of valuable products including sludge based adsorbents, bioflocculants and construction materials is another aspect to achieve sludge valorization. Sludge composting and thermal valorization are also introduced in the mini review since the two strategies could also achieve sludge valorization. In addition, the strategies mentioned were discussed and analyzed in the mini review from environmental and economic aspects. © 2017 Society of Chemical Industry

“…The lack of systematic studies of the illitic clay and bottle glass cullet sintering behavior and the properties of the ceramic materials provide justification for such a study. Some reports have shown the utilization of biomass in porous ceramic material for building applications [16][17][18][19], but the mechanical properties of the bricks were shown to deteriorate. On the other hand, the addition of glass cullet (GC) to the initial clay led to a strengthening of the ceramic body and better performance in terms of mechanical properties and porosity [20][21][22].…”

A mixture of an illitic clay and waste glass was prepared and studied during the sintering process. The illitic clay, from the Liepa deposit (Latvia), and green glass waste (GW) were disintegrated to obtain a homogeneous mixture. The addition of disintegrated GW (5–15 wt% in the mixture) led to a reduction in the intensive sintering temperature, from 900 to 860 °C, due to a significant decrease in the glass viscosity. The addition of GW slightly decreased the intensities of the endo- and exothermic reactions in the temperature range from 20 to 1000 °C due to the reduced concentration of clay minerals. GW reduced the plasticity of the clay and reduced the risk of structural breakage. The increase in sintering temperature from 700 to 1000 °C decreased the apparent porosity and water uptake capacity of the ceramics from 35% and 22%, down to 24% and 13%, respectively. The apparent porosities of all the sintered mixtures showed a decrease of between 6% to 9% after the addition of GW with concentrations from 5 up to 15 wt% respectively, while the water uptake capacities decreased from between 4% and 10%. The addition of GW led to an increase in the apparent density of the ceramic materials, up to 2.2 g/cm3. Furthermore, the compressive strength increased by more than two times, reaching a highest value of 240 MPa after the sintering of the 15 wt% GW-containing mixture at 1000 °C.

“…When the paper sludge quantity increased thickness swelling tends to increase as well. In (Goel & Kalamdhad, 2017), authors find that the addition of paper sludge increases the total porosity of the brick but, decreases the strength. Hydration, mechanical, thermal insulation and sound-absorbing properties of paper sludge ash and cement composites are analysed in (Doudart de la Grée et al, 2018).…”

Paper sludge is the water treatment waste, which produced during paper production. Paper sludge (PS) waste utilization is the common problem in the EU and internationally. According to authors Frías et al. paper sludge is the main waste in the paper processing factories, the percentage reach 35% of product volume. According to the waste management directive No. 2008/98/EC, paper sludge waste should not be utilised in landfills. Such legislation generates the motivation of this study. This study deals with paper sludge as sound absorbing material. In this paper panels made of paper sludge is studied. Sound absorption coefficient of the panels predicted with Horoshenkov and Swift acoustic model for granular media. The aim of this paper is to predict sound absorption coefficient using non-acoustic parameters of the material.
