“…Kataguiri et al (2019) introduced a characterisation flowchart to assess the reuse of excavated soil in the city of Sao Paulo, Brazil. Like in Magnusson et al (2019), the study points to the need of increasing the circularity of excavated soils from construction works in urban areas. Excavated soil, if properly sorted, could be reused on site or redirected to other projects.…”

“…Hence, it is essential to evaluate the potential for increased use of excavated soil for construction purposes on site or in other construction projects, which can be beneficial from a resource conservation perspective. This can enable better control of material flows and avoid quarrying and heavy transport, which have negative environmental effects in terms of energy use and greenhouse gas emissions (Magnusson et al, 2019).…”

“…A better coordination of construction projects could facilitate other applications such as reuse in the construction site or other projects, transport to a recycling facility or preparation for later use. In a later study, Magnusson et al (2019) propose a model to analyse urban soil and rock flows in terms of material quality and their magnitude to evaluate their recycling potential. Kataguiri et al (2019) introduced a characterisation flowchart to assess the reuse of excavated soil in the city of Sao Paulo, Brazil.…”

Soil has been used as building material for thousands of years with a decrease in popularity after the industrial revolution. Nowadays, there is a growing interest in the implementation of unfired soil-based building solutions for their low environmental impact, performances and availability. Traditional soil construction techniques have recurrently included vegetal fibres to enhance soil performance and recent studies highlight a predominant use of agro- and non-agro-waste for unfired soil construction. The article reviews the state-of-the-art of the use of excavated soil and biowaste in the construction industry including a novel focus on urban-only waste and on building technologies using the integration of these two secondary construction material flows. Our literature review highlights a lack of references about the joint use of these secondary resources. Finally, future research orientations are suggested to promote their implementation in the building sector, which could improve urban waste management.

“…For decades, the utilisation of the soils and rocks of concern has been promoted with proper contamination control since large volumes of soils and rocks are usually excavated (e.g. Haid and Hammer, 2009;Katsumi, 2015;Kataguiri et al, 2019;Magnusson et al, 2019;Walsh et al, 2019). For proper utilisation, the leaching characteristics and behaviour of the soils and rocks should be evaluated.…”

Arsenic leaching from shale rock grains was evaluated by the regulatory and modified batch leaching tests. The regulatory test was in according to the Japanese Leaching Test No. 46. The modified batch leaching tests were carried out using de-aired distilled water and eliminating headspace to simulate anaerobic conditions. The results show that dissolved oxygen (DO) in normal batch leaching tests is ~6.0 mg/L. DO can be reduced to ~2.0 mg/L by using deaired water and eliminating the headspace and shaking step. The results suggest that a pseudo anaerobic condition can be achieved by eliminating the headspace and shaking step and conducting the tests in the vacuum deaerator since the DO was very low (~1.1 mg/L). Under the pseudo anaerobic conditions, the arsenic leaching concentrations are lowest (~0.001 mg/L), implying that arsenic leaching might be suppressed under anaerobic conditions. Furthermore, these arsenic concentrations are below the regulatory standard (As < 0.01 mg/L), suggesting that the shale rock grains are environmentally safe for utilisation in geotechnical applications.

“…Despite these difficulties, the benefits from waste geomaterial reuse and recycle are huge and fully recognised in the technical literature [7]; in specific conditions they can lead to significant environmental savings, e.g. a reduction of more than 35% of greenhouse gasses emissions related to soil and rock transportation [8]. Notably, geotechnical works required for transportation infrastructure projects are resourceintensive activities that have high potential for the reuse and recycle of excavation geomaterials [9].…”

Characterisation of geomaterials and non-conventional waste streams for their reuse as engineered materials

Reusing bulk volumes of waste material is a requirement often encountered in mining and construction activities involving excavations. Spoils produced from these activities typically show high variability in terms of properties and behaviour, due to the local geology, adopted excavation method and further spoil treatments. A procedure for classifying the spoil from tunnelling was proposed in order to correlate ground type, possible muck destination and treatment type. With a similar approach in industrial and related sectors, the reuse of non-conventional materials (i.e. wooden chips, fragments, granulates, micronized glass, residual out of shape from manufacturing processes or coming from selection of other waste) has a great relevance as it is accompanied by savings in disposal costs and in the sourcing of raw materials. Characterisation tests derived from geotechnical engineering can support the assessment of the physical and mechanical properties of non-conventional materials, creating a feedback loop encompassing raw material description, required treatments, and possible utilisations as engineered materials. This paper describes the possible screening tests and treatment options for material recycling in the framework of a modified spoil classification system.
