A Primer on Earth Pollution: Pollution Types and Disposal, is an encyclopedia of important research articles and short essays on pollution. Chapters in the initial half provide information about a wide variety of pollutants (dyes and microplastics) and contributing factors (thermal pollution and the impact of GM plants, for instance). Each chapter explains the nature of polluting agents and presents notes and references on preventive measures. Notes on the associated clinical complications due to exposure are also proved where applicable, such as the case of MDR bacteria in marine environments. The latter chapters of the book cover the biotechnology of medical waste disposal using microbes as well as nanotechnology used for limiting the spread of COVID-19. The volume is a handy reference for students and trainees in the field of environmental science as it brings a balance of basic and applied information on the subject of pollution.

Abstract

The paper mills are generating significant quantities of solid wastes and effluent. The scientific ways and means of recycling these solid wastes and effluent in an integrated, eco-friendly manner for agricultural purposes have been the main objective of the present investigation. In brief, in the present investigation, the possible options and potential for agro-cycling of the treated paper mill effluent coupled with the solid byproducts of the industry have been evaluated with special reference to Sugarcane [CO 86032]. The pH and EC of the soil were increased by 0.1 and 0.12 units due to continuous effluent irrigation. The organic carbon content and exchangeable sodium content also increased due to effluent irrigation and solid waste amendments.

Keywords: Biosludge, Effluent, Flyash, Pressmud.

INTRODUCTION

Historically, the discharges from pulp and paper production have long been recognized as a significant source of pollution. Early pollution control initiatives, concentrated upon the loading of suspended solids and biological oxygen demand to the receiving waters [1]. BOD control is still problematic in areas where discharges are made to restricted watercourses or enclosed coastal areas. The pulp and paper industry is one of the largest consumers of water. Nearly 80% of freshwater used in the pulp and paper mill is discharged as effluent, containing organic and inorganic pollutants requiring treatment and disposal. The treated paper mill effluent’s application to cultivated lands is considered to be an in...
