Assessment of Arundo donax Fibers for Oil Spill Recovery Applications
2019
In the last years, natural fibers are increasingly investigated as an oil recovery system in order to overcome the oil spillage phenomena, thus preserving environment and aquatic life. In particular, lignocellulose-based fibers have recently been employed with promising results. In such a context, the aim of this paper is to assess the oil sorption capability of natural fibers extracted from the stem of the giant reed Arundo donax L., a perennial rhizomatous grass belonging to the Poaceae family that grows naturally all around the world thanks to its ability to tolerate different climatic conditions. Sorption tests in several pollutants and water as a reference were carried out. The fibers …
A CARBON CONSTRAINED SOCIETY: THE ECONOMICS OF CARBON CAPTURE, UTILIZATION AND STORAGE
Traditionally carbon dioxide (CO2) emissions has been viewed and treated as a “bad” rather than a “good”. This mental model is of little surprise due to a well-established consensus on carbon dioxide as a pollutant constraining the sustainability of economic and social development at a global scale. In the world where so many actors are preoccupied with shifting towards a low- carbon economy the very idea of carbon dioxide being a commodity (literally and not in the form of carbon caps or quotas trade, in which case a “commodity” is in fact the right to emit carbon, which is in its essence a very different concept) might be a big of a statement. However, this idea is not a mere perspective …
Surface Modified Arundo Donax Natural Fibers for Oil Spill Recovery
2021
The use of green materials for oil recovery applications is the goal to be achieved to reduce the environmental impact of these essential processes. In this context, Arundo Donax L. is a plant known for its wide uses whose absorbent properties have been previously investigated. In this paper, the influence of silane surface treatment on the absorbent behavior of natural fibers extracted from the culms of this eco-friendly and cost-effective material was assessed. A close correspondence has been identified between the physical characteristics of the investigated oil and the fiber size, by means of microstructural and morphological analysis. Excellent results have been achieved with an absorp…
