This paper examines structural dimensions of the influence of core-per iphery relations on adoption of environmental technologies in newly industrializing countries (NICs), using Nordic involvement in development of Southeast Asian pulp manufacturing in the late 1980s and early 1990s as a case study. Contrary to conventional wisdom, Southeast Asia was one of the first places in the world to employ new cleaner technologies in pulp and paper manufacturing. How did this happen? This paper argues that adoption of these technologies was influenced by dynamics within the world-system combined with the intentional actions of firms, states, and social movements over a 30-year period. The paper concludes that diffusion of the new environmental technologies is resulting in cleaner production in the periphery even while being part of a trend toward increased polarization between core and peripheral states, economies, and firms. Data were gathered from fieldwork in Southeast Asia from 1993-96; correspondence with Nordic firms, organizations and individuals in attendance and interviews at industry trade shows; and use of available data. Portions of the paper are derived from a larger study of adoption of environmental technologies in the pulp and paper industries of Southeast Asia and Australia.

Industrial effluent Management is one of the major environmental concerns, especially in developing countries under rapid industrialization. The grossly polluting industries recognized by Central Pollution Control Board (CPCB), such as Pulp and Paper Industries, poses even bigger environmental threats, owing to quantity and quality of effluent generated. This paper aimed at analyzing effluent management practices in pulp and paper industries in India, and asses the performance variability of a paper mill effluent treatment plant (ETP), as a Case Study. Majority of pulp and paper industries found to still employ conventional methods of effluent treatment. Although, most of the parameters of treated effluent are commonly reported within CPCB’s permissible discharge limits, the treatment is usually cost and energy intensive, and produce high amount of solid residuals as sludge. For the case study paper mill ETP, the treatment efficiencies of the ETP units were analyzed under variable inlet pH, TSS, TDS, BOD and COD loads. The pH variations in the range of 6.5 to 9 had little effect of COD or TSS removal, however removal efficiencies were higher for larger inlet COD or TSS loads. The results of the study could be helpful in optimizing operation of the existing ETPs, as well as, guiding on upgrading ETPs with more cost-effective and efficient units.

AbstractWorldwide increased concern of the CO2 emissions has led to the replacement of coal by biomass in combustion-based power plants. However, this would cause the scarcity of fly ash, one of the most well-known rest products from coal combustion, which is used as supplementary cementitious materials (SCM) in construction sector to reduce the large environmental footprint of cement production. Seeking to find alternative SCMs, this article aims to demonstrate the viability of using bio ashes in Sweden as SCM, which, due to lack of studies validating their value, are landfilled today. According to the obtained results, bio ashes produced at pulp and paper industries have a considerably consistent chemical composition and exhibit a satisfactory pozzolanic behaviour. Nevertheless, according to the conclusions of this study, the pozzolanicity of these alternative binders is not reflected equally with respect to the most known reactivity tests for common SCMs. The results imply that although “R3” tests method infers the pozzolanic characteristics of the bio ashes in focus of this study, the “activity index test” as well as “calcium consumption test” indicate otherwise.
