It thus helps address g | d the great challenge we face of replacing non-sustainable fossil resources to or make many of the articles we use in modern society. In fact biomass has a c. s much wider range of applications, some of which have been known for many s.r b years. Two of the other great challenges the world faces—clean water and u p p:// renewable energy—can be partly addressed through the use of biomass and htt these areas are the subject of this book. n o Theuseofbiomasstocleanwaterhasbeenusedbymostlylocalcommunities 3 01 throughout history. Today the increased levels and increased complexity of 2 er pollutants, as well as the increasing demands of a growing population, make b m the clean water challenge especially great. In particular we need low cost, e c e geographically diverse and effective processes. Biomass can fit these require- D 5 ments nicely. . on 0 Biosorption, along with biocoagulation and bioflocculation, has many ad- d e vantagesoverothertechniquesincludingrenewabilityandlowcost.Therearea h s bli vast array of bioresources that can be used in this context including seaweeds, u P fungi,agriculturalby-products,woodyresidues,grassesandbacteria.Thebook alsocoverssoilremediation—anothergreatsocietalchallengeasourfertilesoil levelsdecline.Phytoremediation—theabilityofplantstotakeuppollutants—is anespeciallyinterestingandpowerfulphenomenonwhichisalreadybeingused to decontaminate soils, even those contaminated with military explosives! The removal of hazardous substances is considered along with the mechanisms of adsorption. Many factors can influence the uptake of pollutants by biomass includingpH,temperatureandionicstrength.Alloftheseareconsideredinan attempt to better understand the key biomass–molecule interaction.

In that g | d context, renewable biomass presents both a sustainable energy source and an or alternative to expensive pollution remediation technologies. This book gives c. s an overview of the various ways to valorize biomass for energy production s.r b and for pollution treatment of contaminated soils and waters. It focuses on u p p:// the fact that we could produce renewable energy from biomass without using htt corn, sugarcane or colza oil, but lignocelluloses, bacteria and algae instead. n o Besides, we could treat any water or soil pollution using renewable and 3 01 cheap agro-industrial by-product, algae and fungi. 2 er This book was elaborated considering the biological and physiochemical b m characteristicsofthesebioresources—themajorcriteriaonwhichthechoiceof e c e which application(s) could be reserved for each biomass. Thus, different fields D 5 ofapplication,havingbiomassitselfasthelinkbetweenthedifferentsectionsof . on 0 thepublication.Becausemanyscientificandengineeringdisciplinesaredirectly d e or indirectly involved in the use of biomass for energetic applications and h s bli pollution remediation, the book is deeply multidisciplinary in content and u P treatment of the subject matter. Thus, biologists, chemists, environmentalists, electrochemists and professionals, who are involved in biomass for environ- mentalandenergeticapplications,willcertainlyfindthewholebookorpartof it very insightful and useful for discovering possible applications of locally found biomass(es). The book is divided into two main parts: part 1 made up of chapters 1 to 5 dealswiththeuseofbiomassforpollutionremediationwhilepart2madeupof chapters 6 to9 is dedicated to energy production and storage. Chapter 1 deals with the use of bioresources as an adsorbant for sustainable water treatment processes. The use of biopolymers produced from different biomasses as nat- ural flocculants for water treatment to remove different kind of organic and inorganic pollutant from water streams without prior treatment (i.e. raw RSCGreenChemistryNo.25 BiomassforSustainableApplications:PollutionRemediationandEnergy EditedbySarraGaspardandMohamedChakerNcibi rTheRoyalSocietyofChemistry2014 PublishedbytheRoyalSocietyofChemistry,www.rsc.org vii View Online viii Preface biomaterials)isalsopresented.Chapter2describesthermochemicaltreatments to produce highly efficient activated carbons from various biomasses, their physico-chemicalcharacteristics,andtheirapplicationfortheremovalofheavy metals or organic pollutants such as dyes.

The main criteria are their natural 8 1 8 abilities of extracting the pollution from the soil and ‘processing’ it via 7 9/9 assimilation, degradation or detoxification. Four main aspects of phytor- 3 0 emediation: phytostabilisation, phytodegradation, phytovolatilisation and 1 10. phytoextraction are investigated. Chapter 4 describes the most promising and doi: eco-friendly approaches in soil bioremediation using biomass. The role of g | fungi, bacteria and biomass-derived chemicals such as biosurfactants in these or c. approaches is discussed.

Chapter 9 describes nanoporous car- bonaceous materials produced from biomass, with a large surface area and pore volume, and their use in electrochemical storage systems such as supercapacitors. We sincerely hope that our contribution throughout this book will be a valuable asset to researchers, instructors, decision-makers, practising pro- fessionals, senior undergraduate and graduate students and others interested in pollution remediation and energy production and storage using renewable and low-cost bioresources. The book could even be used as a textbook or reference book for researchers teaching courses dealing with biomass valorisation.
