One of the main sources of water pollution in Taiwan is piggery waste. With the major pollutants such as odors, BOD, TN and TS, waste from the piggery industry has been seriously affecting the environment in Taiwan. However, if this amount of waste is properly treated, it will bring great benefits and can be considered as a resource. Generally, wastewater from the piggery industry is treated in three stages: liquid soil, anaerobic digestion and then aerobic treatment. However, this process is difficult due to high cost and difficult operation. Therefore, a feasible method was to establish a centralized methane production facility for the treatment of piggery industrial waste. The products after treated like methane and fertilize are utilized as clean and environmentally friendly products. Methane can be used for cooking or electricity generation. This is a new direction suitable for sustainable development.

Water is an essential element for human life but is being wasted and made unsafe due to anthropogenic activities and pollution. In Bangladesh, both surface water and groundwater are being polluted due to the rapid growth of urbanisation and industrialisation, and most importantly, arsenic contamination and industrial waste are affecting the potability of this natural resource. Bangladesh is a highly polluted country that faces a scarcity of clean water, despite having an abundance of water sources. This article presents a range of examples of existing environmental pollution in Bangladesh before focusing on water pollution and its causes and consequences. In addition, this article discusses how inefficient water management and poor law enforcement have failed to ensure environmental justice for the citizens of Bangladesh. Finally, this article concludes with observations about some ways forward to ensure water justice, enable access to clean water for all and achieve sustainable development in Bangladesh.

In the paper experiments and theory of biogas production using industrial waste from paper production as a co-substrate are described. The main aim of the experiments was to evaluate the sensitivity and applicability of the biochemical conversion using the anaerobic digestion of the mixed biomass in the pilot fermentor (5 m3), where the mesophillic temperature was maintained. It was in parallel operation with a large scale fermentor (100 m3). The research was carried out at the biogas plant in Kolíňany, which is a demonstration facility of the Slovak University of Agriculture in Nitra. The experiments proved that the waste arising from the paper production can be used in case of its appropriate dosing as an input substrate for biogas production, and thus it can improve the economic balance of the biogas plant.

AbstractThe implementation of circular economy in wood industries is an effective way for future sustainable development. The wood industries in China are not in the direction of circular economy approach due to less availability of assessment/calculation data of pollutants as per life cycle assessment (LCA) criteria. The present study focuses on the calculation of emission and pollutants from wood industries as per LCA; the emission and pollution data were collected from fiberboard Medium-density fiberboard (MDF), plywood and particleboard (PB) production. The comparative analysis of dust emissions, industrial waste gases and chemical oxygen demand (COD) were performed among three wood industries. The results revealed that the fiberboard industry was the highest emitter of dust, industrial waste gas and COD; and particleboard industry was the least emitter. Further, results indicated that pollutant index of wood industries were significantly changed between 2015 and 2017; the industrial waste water discharge increased five folds and the COD, dust and industrial gases increased two times. This study provides with the emission and pollutants data of wood industries as per LCA to promote the sustainable development for circular and low carbon economics.

Feasible Method

Anaerobic digestion can be an attractive and economically feasible method for the treatment of piggery wastes, provided that maximization of gas production and efficient subsequent utilization can be attained. Expedience from anaerobic digestion of domestic sludges can not be directly transferred to the design of digestion treating piggery wastes, due to the particular characteristics of the latter. The sequential anaerobic degradation of these wastes favours the adoption of short retention times for maximum gas production while at the same time satisfactory stabilization can be obtained.

Contamination Of Soils

As a result of accidental spills or leaks, industrial wastes may enter in soil and in streams. Some of the contaminants may not be completely removed by treatment processes; therefore, they could become a problem for these sources. The use of synthetic products (e.g. pesticides, paints, batteries, industrial waste, and land application of industrial or domestic sludge) can result in heavy metal contamination of soils.

This chapter addresses a typical borderland environmental problem—transboundary air and water pollution. During the 1970s and 1980s, rivers carried eastern industrial waste and sewage into West Germany; the wind blew sulfur dioxide both ways. Their environmental interdependency forced both German states to the negotiating table, eventually producing the ineffectual Environmental Accords of 1987. The western encounter with eastern pollution through the interface of the inter-German border confronted West German authorities with early signs of East Germany’s dissolution. While they failed to grasp the message, their experience with East German pollution and the futile diplomatic efforts to curb it nonetheless generated the knowledge about the nature and extent of the GDR’s environmental problems that became the prerequisite for the post-1990 ecological restoration of East Germany.

This chapter looks at the obligation not to cause significant pollution to other states sharing freshwater resources, and of the emerging obligation to protect the ecosystems of international watercourses. While problems of water pollution have perhaps received more attention in the literature, it seems probable that the protection of watercourse ecosystems is of wider significance, in terms of geography, meeting basic human needs, and sustainable development. Sustainable development was endorsed at the 1992 Earth Summit as the proper approach to reconciling economic development with protection of the environment. It aims at ensuring that economic development will not exhaust the very resources on which it, and human welfare itself, depend. Clean water and healthy aquatic ecosystems are cornerstones of this effort. International law has now progressed to the point that it protects those values.

Substrate Type

Anaerobic digestion is an efficient technology for a sustainable conversion of various organic wastes such as animal manure, municipal solid waste, agricultural residues and industrial waste into biogas. This technology offers a unique set of benefits, some of which include a good waste management technique, enhancement in the ecology of rural areas, improvement in health through a decrease of pathogens and optimization of the energy consumption of communities. The biogas produced through anaerobic digestion varies in composition, but it consists mainly of carbon dioxide methane together with a low quantity of trace gases. The variation in biogas composition are dependent on some factors namely the substrate type being digested, pH, operating temperature, organic loading rate, hydraulic retention time and digester design. However, the type of substrate used is of greater interest due to the direct dependency of microorganism activities on the nutritional composition of the substrate. Therefore, the aim of this review study is to provide a detailed analysis of the various types of organic wastes that have been used as a substrate for the sustainable production of biogas. Biogas formation from various substrates reported in the literature were investigated, an analysis and characterization of these substrates provided the pro and cons associated with each substrate. The findings obtained showed that the methane yield for all animal manure varied from 157 to 500 mL/gVS with goat and pig manure superseding the other animal manure whereas lignocellulose biomass varied from 160 to 212 mL/gVS. In addition, organic municipal solid waste and industrial waste showed methane yield in the ranges of 143–516 mL/gVS and 25–429 mL/gVS respectively. These variations in methane yield are primarily attributed to the nutritional composition of the various substrates.
