Amounts of non-fibrous components in recovered paper

Paper and board recycling is now a central issue in papermaking. Understanding of material flows, as a part of the total production chain, as well as, fibrous and non-fibrous component flows needs further clarification. These flows are studied at a European level, with special focus on Germany and Sweden. Non-fibrous components are discussed in terms of a material which hampers the processing of paper and board. Resource-efficiency improvements, in conjunction with economic benefits, are sought and recycling has been able to fulfil both of these. The main drivers to maximize the use of recovered paper in paper and board manufacturing, have been improved over the last decades. These drivers are cost, environmental image and good technical properties to be used as raw material.The increased recycling rate has reduced the quality of the collected paper, produced recycled paper, and replaced virgin pulp. Also, recycling as a process, like deinking, produces large amounts of waste material that has challenges to find proper utilization. These problem areas are addressed in this paper, too.One focus area in the analysis of statistical information is an estimation of the share of non-fibrous components and fibre volumes of paper in Europe (EU) for the year 2010.     

Co-pyrolysis of paper waste and mustard press cake in a semi-batch pyrolyzer—optimization and bio-oil characterization

Under the present research study, the co-pyrolysis of paper waste and mustard press cake was conducted in a 50 mm diameter and 640 mm long semi-batch pyrolyzer in the temperature range of 673 to 1173 K in nitrogen atmosphere and synergistic relationship between the pyrolysis of two feed stocks has been observed. The paper wastes were composed of local packing paper, newspaper-based food packets of grocery, and printing paper in the ratio of 6:3:1. During co-pyrolysis, response surface methodology (RSM) technique has been employed using Design Expert Version 7.0.0 to determine the collective effects of factors, namely, A: ratio of paper waste to mustard press cake and B: pyrolysis temperature, on the yield of bio-oil, energy yield, and oxygen content of bio-oil. Optimization has been done by using RSM to identify the individual sets of values of independent parameters corresponding to maximum bio-oil yield (A: 9.0:1, B: 874.75 K), energy yield (A: 8.80:1, B: 812 K), and minimum oxygen content of bio-oil (A: 2.75:1, B: 883.06 K). Bio-oil obtained at maximum energy yield condition has been characterized using the Gas chromatography–mass spectrometry (GC-MS) and Fourier transform infrared spectroscopy (FTIR) spectroscopic analyses. The array of compounds present in the bio-oil compounds has been compared with literature data available on pyro-oil obtained from similar feed stocks.     

Small-scale mining in Ghana: The government and the galamsey

This paper argues that the current formalization system for small-scale gold miners in Ghana has been undermined and the small-scale mining laws no longer capture the reality of the sector’s activities. The paper will examine the small-scale mining system and shows that registered and unregistered actors operate not only in parallel but are actually intertwined and highly dependent on one another. The paper shows that the perceived dichotomy of formal and informal actors in the sector does not actually exist. The sector has instead evolved into a highly intertwined group of semi-formal sectors operating with varying degrees of legal registrations. The paper concludes that political leniency and law enforcement corruption has resulted in a booming small-scale gold system under poor government control. The paper recommends that politicians move to enact reforms to regularize the small-scale mining sector and curtail ubiquitous environmental and occupational safety problems. Anti-corruption initiatives and law enforcement reforms are the most urgent. However, reforming the laws is also necessary to capture and regulate the technological innovations the sector is currently using.

Implementing Sustainability: the Use of Natural Channel Design and Artificial Wetlands for Stormwater Management

Sustainability is a concept that has been widely embraced both politically and intellectually but has not been addressed in terms of practical application. In most resource sectors, the features of a sustainable future remain unclear and there are few examples that give practical expression to sustainability. This is especially true in the case of water resources management which has been conspicuous in its absence from the majority of the literature. This paper attempts to address this deficiency on two counts. First, it provides a discussion of sustainability and the application of the concept to the management of water resources. Second, the paper illustrates how the concept can be utilized for the management and planning of urban stormwater. The paper concludes by offering research opportunities to investigate the feasibility of adopting natural channel design and artificial wetlands for sustainable stormwater management.
