“…The initial screening performed by researchers screened out articles that studied waste management out of or extending beyond the C&D sectors. For example, Fagnani and Guimarães 2017and Jones et al (2009), though targeting waste processing and management, did not focus on the C&D industry. Other studies such as Dong and Lee (2009), Pattnaik and Reddy 2010, as well as Staley and Barlaz (2009) focused on a larger scope (e.g., solid, municipal, or industrial wastes), which covered the C&D waste but was not limited to it.…”

Sustainable treatments of construction and demolition (C&D) wastes have become an increasingly urgent social, environmental, and economic issue worldwide. Based on a filter of 370 articles related to C&D waste management, this review-based study adopted a science mapping approach to evaluating the recent decade's C&D waste management research. Through a three-step workflow consisting of bibliometric literature search, scientometric analysis, and qualitative discussion, this study identified the most influential journals, scholars, articles, and countries that have been active and influential in the C&D waste management research since 2009. Keyword analysis revealed the emerging research topics, such as BIM, prefabricated construction, Big Data, and Circular Economy. The follow-up discussion summarized the mainstream research areas (e.g., qualification of waste generation), discussed research gaps (e.g., integration of BIM and Big Data into C&D waste management), and proposed the framework for near-future research, such as a comprehensive evaluation of the performance of C&D waste diversion, human factors, and design and planning for waste diversion. By providing the big picture of the latest research in C&D waste management since 2009, the paper serves as a multidisciplinary guide for practitioners and researchers to link current research areas into future trends.

“…The main growth parameters recorded were plant height, stem width, leaf blade width, root dry biomass, and above-ground biomass dry weight. The root dry biomass of each plant was determined by separating the roots from the soil by washing with sufficient water and drying the sample at 80°C for 48 h. Above-ground biomass dry weight of each plant was determined after drying the sample in a drying oven at 80°C for 48 h ( Jones et al., 2009 ). All such measurements reported in the results section were averaged among all collected plants from each microplot, and standard deviations values were calculated.…”

Optimizing Inorganic Carbon Sequestration and Crop Yield With Wollastonite Soil Amendment in a Microplot Study

Carbon dioxide (CO 2) is a major greenhouse gas, and its concentration in the atmosphere is increasing continuously, hence there is an urgent need to reduce its level in the atmosphere. Soils offer a large natural sink to store CO 2. This study focuses on sequestering CO 2 in the agricultural soils as inorganic carbon, which can be accomplished by adding alkaline-earth silicates. Wollastonite is used in this study as a soil amendment, to sequester CO 2 via the geochemical route of mineral carbonation. The first objective of the present study was to evaluate the effect of mixing a wide range of dosages of wollastonite, as a soil amendment, on the growth performance of two leguminous plants frequently used in agricultural sector: soybean and alfalfa. The plants were grown with different wollastonite dosages (3-20 kg•m −2 for soybean and 3-40 kg•m −2 for alfalfa), for a duration of 14 weeks in a microplot experiment in Ontario, Canada. The second objective was to find evidence of enhanced weathering of wollastonite in soil, in addition to the augmentation of inorganic carbon content in soil. For this, mineralogical assessment of the soils was performed using XRD and SEM-EDS analyses. Wollastonite increased the soybean yield by twofold in the plot amended with 10 kg•m −2. At all dosages, wollastonite increased the alfalfa growth in terms of height and above-ground biomass dry weight, as well as root biomass. The rate of CO 2 sequestration, at optimum wollastonite dosage, reached 0.08 kg CO 2 •m −2 •month −1. XRD and SEM-EDS analyses indicated accumulation of calcite in wollastonite-amended soil and formation of other weathering products. The results obtained from this study help to understand the impact of wollastonite soil amendment on agronomy, and will aid in implementing such negative emissions technology by informing farmers and industry alike that the use of wollastonite contributes toward global climate change mitigation while supporting crop yield. The findings of this study add to the existing body of knowledge on enhanced weathering as an atmospheric CO 2 removal technology, providing further evidence that wollastonite weathering in agricultural soils can lead to significant capacity for CO 2 sequestration as inorganic carbon, while concurrently promoting plant growth.

“…Indeed, few studies have considered mixed waste streams for composting (Jones et al, 2009) and therefore scientific studies are required to demonstrate their cleanliness and effectiveness in supplying nutrients.…”
