Permeable Concrete Barriers To Control Water Pollution: A Review, Rehab O. Abdel Rahman, Ahmed M. El-Kamash, Yung-Tse Hung

Civil and Environmental Engineering Faculty Publications

Permeable concrete is a class of materials that has long been tested and implemented to control water pollution. Its application in low-impact development practices has proved its efficiency in mitigating some of the impacts of urbanization on the environment, including urban heat islands, attenuation of flashfloods, and reduction of transportation-related noise. Additionally, several research efforts have been directed at the dissemination of these materials for controlling pollution via their use as permeable reactive barriers, as well as their use in the treatment of waste water and water purification. This work is focused on the potential use of these materials as …

Wastewater Remediation Technologies Using Macroscopic Graphene-Based Materials: A Perspective, Rajan Arjan Kalyan Hirani, Abdul Hannan Asif, Nasir Rafique, Lei Shi, Shu Zhang, Hong Wu, Hongqi Sun

Research outputs 2014 to 2021

Three-dimensional (3D) graphene-based macrostructures are being developed to combat the issues associated with two-dimensional (2D) graphene materials in practical applications. The 3D macrostructures (3DMs), for example, membranes, fibres, sponges, beads, and mats, can be formed by the self-assembly of 2D graphene-based precursors with exceptional surface area and unique chemistry. With rational design, the 3D macrostructures can then possess outstanding properties and exclusive structures. Thanks to various advantages, these macrostructures are competing in a variety of applications with promising performances unlike the traditional activated carbons, biochars and hydrochars, which have less flexibilities for modifications towards versatile applications. However, despite having such …

Biochar And Ash Amendment Effects On Mine Reclamation In The Boreal Forest, Jillian M.H. Bieser, Sean C. Thomas

Biochar: Production, Characterization and Applications

Natural re-vegetation of gold mine tailings, the main waste products of ore processing for gold extraction consisting of crushed rock, is difficult due to their high bioavailability of heavy metals, low nutrient status and limited organic carbon 1-3. Charcoal produced from the burning of organic matter through controlled pyrolysis, hereafter referred to as ‘biochar’, has been utilized extensively in agriculture as a climate-friendly option to remediate nutrient-poor and contaminated soils 4,5. Biochar produced from wood is highly recalcitrant, has a large surface area due to its porous structure and can bind nutrients and water, improving soil fertility 5-7. Biochar can …

A Three-Stage Thermochemical Conversion Process For The Production Of Biochar, Alessandro Scova, Vander Tumiatti, Francesco Lenzi

Biochar: Production, Characterization and Applications

Within a French consortium of four companies and five laboratories from two scientific groups, Sea Marconi is one of the industrial partners of the LORVER project (www.lorver.org). The project aims at the sustainable redevelopment of brownfield deriving from the deindustrialization of the Lorraine region (France) by soil reconstruction, cultivation of different non-food biomasses and their final conversion into valuable outputs (biochar, bioenergy, natural fibers, metals).
