Insights into the resources generation from pulp and paper industry wastes: Challenges, perspectives and innovations.

• Waste generated from pulp and paper industry is revisited. • The review covers serious impacts of waste on human health and environment. • Resource generated (energy, product) from different waste materials are reviewed. • Alternative resource generation reduces pollution load of industry. • Integration of industries for waste utilization will help in zero waste emission. Pulp and paper industry is swiftly budding to fulfill industrial needs and with the growth of this industry, a large amount of waste has also generated which includes biological sludge generated from the wood digestion process, fly ash accumulation and lime mud produced in chemical reagent recovery circuit. There are many health hazards associated with generated wastes and this waste material can be utilized in sustainable ways to generate useful resources through technological innovations. This review highlights a few useful aspects of waste conversion to resources like the production of green energy, sorbent development, and clinker preparation. The generation of resources from such wastes is a revolutionary and innovative concept for sustainable development including valorization of the generated waste to integrate pulp and paper industry with biorefinery. This review paper focuses on the sustainable utilization of waste from such industry along with its efficiency and future challenges. [ABSTRACT FROM AUTHOR]
