“…Cement in infrastructure projects has prompted a number of researchers to come up with innovative ideas for reducing their impact on the environment. In one such study Folorunso and Anyata (2007) developed a ceiling board by the utilization of paper sludge as replacement for cement by 2 and 4%. The study concludes that, it is feasible to use paper sludge as substitution for cement for production of ceiling board.…”

PurposeThe growing quantity of waste is a worrying reality that has resulted in environmental sustainability challenges. Waste paper sludge (WPS) in large quantities from paper mill industry are produced every year. Their disposal in landfills, in general, pollutes the environment. Cement manufacture also contributes to global warming by emitting carbon dioxide. As a result, a novel use of industrial wastes as a supplemental cementitious ingredient in concrete formulation can help to mitigate the environmental problem. This paper aims to study the possibility of usage of WPS as partial replacements of cement for sustainable development of concrete.Design/methodology/approachThis study aims at testing the mechanical properties of concrete that has been mixed with WPS. Between 5% and 20% of the weight of cement, WPS was used to substitute it. The water binder ratios of 0.55, 0.50, 0.45 and 0.42 were all considered for an experiment to better understand the impact of WPS on concrete. In terms of workability, density, water absorption (WA), compressive strength (CS) and flexural strength (FS), concrete mixtures were created, tested and compared to traditional concrete mixes.FindingsAccording to the findings, the initial and final setting times of the concrete mixtures were both significantly delayed, and the workability and density of the concrete mixtures were both significantly lowered at all water binder ratios and replacement levels. Both compressive and FS of concrete made with WSP declined significantly at all water binder ratio. Substitution of cement by WPS enhanced the WA of all the concrete mixes. The mechanical performance of concrete mixtures that were made with a replacement level of 5% exhibited noticeable improvements. Whereas the more is the replacement levels the more the loss in the mechanical properties were noted. The ideal replacement levels for the WPS are up to 5% only.Originality/valueThis paper contributes to the literature by exploring the ecological and sustainable effects of using WPS in construction materials.

“…Berdasarkan data ini, pemberian konsentrasi asetat anhidrida 3% sangat baik direkomendasikan karena memiliki kadar air yang paling rendah. Bila dibandingkan dengan papan semen yang dibuat dari sludge, nilai pengembangan tebal hasil penelitian ini lebih baik dari nilai pengembangan tebal papan semen sebesar 7,9% [13]. Dengan kata lain, papan yang dihasilkan dari penelitian ini mempunyai kualitas yang lebih baik dibandingkan dengan papan semen dengan bahan baku yang sama.…”

AbstrakPenelitian pemanfaatan sludge sebagai bahan baku pembuatan papan serat berkerapatan sedang atau medium density fibreboard (MDF) berguna untuk menciptakan nilai tambah dari sludge. Tujuan dari penelitian ini adalah mengevaluasi sifat fisis, mekanik, dan ketahanan MDF dari sludge terasetilasi dengan 4 macam konsentrasi asetat anhidrida (0%, 3%, 5% dan 7%) dengan 3 kali ulangan. Pembuatan MDF dilakukan dengan proses kering. Setelah bahan baku dicampur perekat, dilakukan pengempaan dengan menggunakan kempa panas dengan suhu AbstractMedium Density Fibreboard Made of Acetylated Sludge from Paper Mill. Research of using sludge as raw material for making medium density fibreboard (MDF) was useful to create additional value of sludge. The objective of the research was to evaluate physical properties, mechanical properties, and durability of MDF from acetylated sludge in 4 levels of acetate anhydride (0%, 3%, 5%, and 7%) with 3 replicates. The MDF was made using dry process. After materials were mixed with adhesives, they were pressed using hotpress under 170 o C temperature and 45 Pa pressure for 25 minutes. The size of the MDF sample was 25 cm x 20 cm x 1 cm with 0.8 g/cm 3 density. The physical properties (density, moisture content, water absorption, thickness swelling) and mechanical properties (modulus of elasticity, modulus of rupture, internal bond, screw holding power) was tested based on JIS A 5905-2003 standard. The durability was evaluated using SNI 01-7207-2006. All physical properties of MDF fulfill JIS A 5905-2003. Acetate anhydride decreased the moisture content value of MDF. On the other hand, all mechanical properties did not fulfill the standard. That was caused by calcium carbonate in sludge that blocked the adhesion between sludge fibres. The durability of MDF tested here was classified Class I which is very resistant to termites.

“…According to a February 2020 report released by the International Energy Agency, the global energy-related carbon dioxide emission plateaued in 2019 at 33 Gt. Though waste paper and its ashes are found to be useful for the production of thermal insulation panel products/ceilings [31][32][33][34][35][36] and preparation of concrete [37,38] as well, there is a need to further devise a scientifically-safe way of minimizing the huge quantity of such waste materials for beneficial purpose(s). Hence, by carefully considering the aforementioned situations in the light of a sustainable building design, this study is designed to assess the feasibility of utilizing hydrothermally-calcined waste paper ash nanomaterial (HCWPAN) as an alternative stabilizer to cement for clay modification for building purposes.…”

It has been observed that clay soil cannot be used for building design, unless it is modified by firing or with cement. Either method of stabilization can adversely affect the environment and public health just like indiscriminate dumping or open burning adopted in developing countries as the prevalent disposal technique for waste papers. This paper sought to examine the feasibility of using assorted waste papers to derive an alternative stabilizer to Portland Limestone Cement for modification of clay soil into composite materials suitable for building design. Specifically, clay-based composites were fabricated at 0 %, 5 %, 10 %, 15 %, and 20% replacement levels by weight with cement, and then hydrothermally-calcined waste paper ash nanomaterial (HCWPAN). Water absorption, sorptivity, bulk density, thermal conductivity, specific heat capacity, thermal diffusivity, flaking concentration, flexural strength, and compressive strength were investigated for each of the fabricated samples. Irrespective of the stabilizing agent utilized, 10% loading level was found to be the optimum for possession of maximum mechanical strength by the samples. Only samples with the HCWPAN content were found to be capable of reducing building dead loads and improving thermal insulation efficiency over un-stabilized clay material, if applied as walling elements in buildings. Generally, it was revealed that the cement and HCWPAN have comparable influences on the properties of clay soil, thus indicating that HCWPAN could be utilized as an alternative stabilizer to cement. In addition, the preparation of HCWPAN was found to be more energy-saving than that of the cement.
