“…Ahlam et al, also showed the utilization of cardboard waste nearly 25 gm/l of the substrate with 2.95 FPU/ml, which is quite higher than the observation treatment first, then further for enzymatic hydrolysis [31]. Similarly, newspaper, filter paper and other substrates were also tested for cellulose hydrolysis [32]. Here in this study, maximum enzyme activity was found with cardboard substrate i.e.…”

“…Waste paper is part of lignocellulosic waste and its accumulation is a major problem in many countries such as China (Zhao et al, 2013), India (Zhao et al, 2014), UK (Cesaro and Belgiorna, 2014) and also most countries in Africa (Tonn, 2002). Cellulase enzymes are described as suitable biocatalysts that could be used for the effective bioconversion of lignocellulosic waste such as waste paper into fermentable sugars and reports on the bioconversion of newspaper (Van Wyk et al, 1999), office paper (Ikeda et al, 2006) viride.…”

The search and development of alternative and renewable energy resources are issues that should become more topical as the negative effect of fossil fuels on the environment is experienced. Also of environmental importance is the management of huge volumes of solid waste produced annually. Waste paper is the major component of organic solid waste and during this investigation the relative saccharification of eight different waste paper materials with cellulase from Trichoderma viride has been concluded. Different sugar releasing patterns have revealed the difference in susceptibility of different organic waste materials for cellulase catalyzed bioconversion into sugars. The highest extent of degradation was observed with brown envelope paper followed by cardboard while the least susceptibility for this process of degradation was experienced with newspaper. The pH value of all incubation mixtures changes between values of pH 5.0 to pH 7.0 during the 51 hours of cellulase catalyzed bioconversion.

“…The majority of this amount is either dumped or burnt and this significantly increases the rate of environmental pollution (Ojewumi et al, 2018). Even in cases of recycling, a huge amount of paper materials are produced from virgin fibers which make for good quality paper but recycling of such paper leads to lower quality of the paper, and with increasing uses of paper, there arises a huge demand of the environment to deal with the increasing amounts of waste paper (van Wyk et al, 1999;van Wyk and Mohulatsi, 2003). In a bid to control this, several alternatives have been looked into and invented for the possible conversion of the cellulosic content in paper and other waste materials into fermentable sugars such as glucose (Ojewumi et al, 2018;Ojewumi et al, 2019d).…”

“…Limiting environmental pollution by recycling wastes into usable items is not the only good thing recycling brings to the table but it also helps to protect and conserve our natural resources. An environmentally friendly way of achieving this is by the enzymatic catalysis of naturally derived waste such as paper materials into fermentable sugars, for example, glucose (van Wyk et al, 1999).…”

Pollution generated by solid waste has become a massive source of concern worldwide as the amount of waste being generated has become overwhelming. Waste paper contributes significantly to the overall solid municipal waste being generated daily and with control methods that are equally bad for the environment or just plain ineffective; better, effective, and environmentally friendly control solutions are required. This study reviews the use of various microorganisms as they aid in the control of waste papers in an environmentally conscious way. In addition to being an environmentally friendly solution to the issue of solid waste paper pollution, it is also a prominent source of renewable energy in the conversion of paper into fermentable sugars for the production of bio-ethanol. This review examines the vital revolution in the enzymatic hydrolysis of paper to sugar. Salient challenges that involve bioconversion were highlighted and a few solutions were suggested.
