Pulp and paper mill industries are always associated with the
disposal problem of highly contaminated sludge or bio-solids. The
development of innovative systems to maximize recovery of useful
materials and/or energy in a sustainable way has become necessary.
The management of wastes, in particular of industrial waste, in an
economically and environmentally acceptable manner is one of the
most critical issues facing modern industry, mainly due to the
increased difficulties in properly locating disposal works and
complying with even more stringent environmental quality
requirements imposed by legislation. This book presents a general
Introduction on waste management in the pulp and paper industry and
contains topics on the generation of waste in pulp and paper mills,
waste composition, methods of sludge pre-treatment, processes and
technologies for conversion of pulp and paper mill waste into
valuable products, waste reduction techniques employed in the pulp
and paper Industry worldwide and future trends.
The socio-economic activities due to world development are
promoting increasing pressures on land, creating competition and
conflicts, resulting in suboptimal use of resources. Integrated
planning and management of land resources is a top subject of
Agenda 21 (managed by FAO), which deals with the cross-sectoral
aspects of decision-making for the sustainable use and development
of natural resources. This is essential for life-support systems
and its productive capacity. In this context, there is a need to
find new strategies for sustainable development that links social
and economic progress with environmental protection and
enhancement. Electrokinetic transport processes (EK) uses a
low-level direct current as the "cleaning agent". EK has been
applied to the remediation of polluted soils and other contaminated
matrices. It also shows a great potential to be used in different
fields, as in saline soil restoration, nutrients recovery from
wastes or repair and maintenance of building structures. EK may be
an integrated approach for new strategies aiming at sustainable
development and to support waste strategies, with worldwide
interest. EK can also be coupled with phytoremediation and
integrated with nanotechnology, enlarging the scope of its
application. The conciliation of the EK in the recovery of
secondary resources, remediation and conservation is a
multidisciplinary novel approach that opens new technical
possibilities for waste minimization, through upgrading of
particulate waste products and the recovery of secondary resources
for industrial, agricultural or social use.

Today synthetic dyes are used extensively in the textile dyeing,
paper printing, color photography, pharmaceuticals, food and drink,
cosmetic and leather industries. As of now, over 100,000 different
dyes are available, with an annual production of over 700,000
metric tons. These industries discharge an enormous amount of
colored effluents into natural water bodies, with or without
treatment. The textile industry alone discharges 280,000 tons of
dyes every year, making it the largest contributor to colored
effluent discharge. Although a variety of treatment technologies
are available, including adsorption, chemical oxidation,
precipitation, coagulation, filtration electrolysis and
photodegradation, biological and microbiological methods employing
activated sludge, pure cultures, microbial consortia and
degradative enzymes are economically viable, effective and
environmentally responsible options. As such, this book gathers
review articles from international experts working on the microbial
degradation of synthetic dyes, offering readers the latest
information on the subject. It is intended as a quick reference
guide for academics, scientists and industrialists around the
world.
