Biodevelopment of Wastepaper as a Resource of Renewable Energy:  Influence of Enzyme Concentration and Paper Amount on the Bioconversion Process

Abstract

Renewable energy would become more topical as natural energy resources are depleted. Also a major global issue is the extent of solid waste generation of which biowaste is the main component and development of its bio-energy potential can address issues such as renewable energy and environmental pollution, simultaneously. Used paper is a primary component of biowaste with cellulose its dominant structural biopolymer. Various used paper materials have been treated with a cellulose hydrolyzing enzyme from Penicillium funiculosum to bioconvert their cellulose component into sugars such as glucose that could be utilized as feedstock for the synthesis of biodegradable products such as bio-ethanol. These paper materials exhibited nonsimilar susceptibilities toward this cellulase enzyme and consequently different sugar releasing and bioconversion efficiency patterns were obtained when changing quantities of each paper were treated with a fixed amount of enzyme. When a fixed amount of each paper material was treated with increasing enzyme concentrations, different bioconversion and efficiency profiles were also constructed for each paper material biodegraded.

Electrochemical Capacitance of Nanocomposite Polypyrrole/Cellulose Films

“…In recent years, there has been a significant increase in research devoted to the applications of cellulose, particularly due to the increasing interest in the use of renewable, environmentally benign materials. , Applications of cellulose include uses in structural reinforcement of materials, , smart materials and dialysis membranes. , Cellulose nanocrystals (CNXLs) can be extracted from natural cellulose resources, and these renewable nanomaterials have attracted attention recently for a number of applications due to their cost effectiveness, ease of preparation, mechanical strength, and biocompatibility. − The surfaces of the CNXLs also contain functional groups that can be modified to introduce functionality to the crystal exterior. − …”

UCST-Type Soluble Immobilized Cellulase: A New Strategy for the Efficient Degradation and Improved Recycling Performance of Wastepaper Cellulose

“…As an emerging technology, bioenzymatic catalysts have gained widespread application in the wastepaper processing industry due to their fast reaction rates, mild reaction conditions, and minimal environmental pollution [ 4 , 5 , 6 ]. Enzymes, commonly employed as biocatalysts, can significantly improve the hydrolysis rate of cellulose and reduce the energy consumption for pollution treatment when utilized in wastepaper pulp processing.…”

Bio-inspired writable multifunctional recycled paper with outer and inner uniform superhydrophobicity

“…[1][2][3][4] Recycled paper, for the moment, must be the best answer to solve these problems. [5][6][7] The process of recycled paper involves mixing used paper with water to break it down. Aer being chopped up and heated, it is further broken down into strands of cellulose, which is calling pulp or slurry.…”
