Abstract Wood has been used as an engineering material because it is low in cost, renewable and strong and it requires low processing energy. Wood has many excellent properties that result from its exceptional combination of microstructural, ultrastructural and molecular features. The main drawback is its dimensional instability in the presence of moisture, which can affects also the biological stability. Wood is susceptible to degradation in a number of ways, including rot or decay, insect a...

Abstract The cleanup of environmental pollution involves a variety of techniques, ranging from simple biological processes to advanced engineering technologies. Cleanup activities may also address a wide range of contaminants. Technologies to remediate contaminated soil fall into two principal clean-up approaches: in-situ (which is always done onsite), or ex-situ (which can be done on- or off-site). In-situ treatment deals with contamination without removing material from the ground, while ex...

Abstract Characterization of soil permeability is of great importance for several geotechnical analyses. In common practice, because of the difficulty in sampling of granular material, constant head permeability tests are usually employed on specimens having similar relative densities to those in the field. An alternative approach to permeability tests for granular soils is the prediction of permeability levels by means of empirical equations depending on several particle size distribution an...

AbstractOceans have been proved to be an important resource due to their abundant reserves in oil and gas. However, because of the extent of oil exploration and development in recent years, the marine ecological environment has been increasingly affected. At present, the control and treatment of environmental pollution from offshore drilling both at home and abroad have focused on end-treatment after problems have already emerged. Nevertheless, preventative measures and appropriate control links...

Improving the awareness of the responsibility of our actions is the basis of achieving the ambitious aim of waste management and prevention established by the European Waste Framework Directive 2008/98/CE and the most recent Circular Economy Package. Circular Economy is connected both to improve manufacturing technologies and also educate people towards responsible consumption and waste reduction. Due to its educational and institutional role, universities provide a context to rethink not on...

Carbon Footprint (CF) is an environmental indicator used in Life Cycle Assessment (LCA) that allows measuring the total amount of CO2 emissions caused directly or indirectly by an activity or accumulated through the life cycle stages of a product (ISO 14064-14067). In this article CF was used to analyse and assess the environmental impacts of the resources used for the collection of municipal solid waste by the company Contarina S.p.A. Contarina oversees waste management for part of the Treviso...

A light-driven dissipative engine, which must necessarily operates at a nonzero rate and far from equilibrium to be capable of providing power and work, is investigated in this paper. On the basis of the assumptions that the heat exchange between the working fluid and the environment obeys the linear phenomenological heat transfer law [ q  (T 1) ], the piston trajectories minimizing the entropy generation are determined. Furthermore, numerical examples are provided for...

Acid-base accounting was applied to evaluate the acid generating potential of waste rock dumps of different ages at a nickel mine in Zimbabwe. Metal concentrations in soils surrounding the dumps were also assessed. The net neutralising potential (NNP) of waste rock samples was derived from the maximum potential acidity (MPA) and the neutralising potential (NP). MPA and NP were determined based on total sulphur and acid consumption respectively. Waste rock dumps (WRDs) had more (p<0.05) su...
