“…Tunnel ventilation facilities are used to capture vehicle exhaust emissions within a tunnel and released it into the atmosphere using a "smoke stack" (Chang et al, 2020). Longer tunnels require ventilation stacks to regulate the air quality within the tunnel and ensure that it is suitable for human health and are often situated as close as possible to the tunnel portals, usually at the start and the end (Liu et al, 2020). Two ventilation facilities are being constructed within the Rozelle Interchange and Iron Cove Link, one of which will be the largest ventilation structure in the southern hemisphere (Thomy and Merrick, 2018).…”

Many city's current transport infrastructure is deemed to be inadequate for rapid population growth and projected urbanisation, driving an increase in the construction of more efficient and reliable transport infrastructure and networks. However, transport infrastructure projects have negative impacts on the environment, during both the construction and operational phases.Green wall technologies have become an increasing trend within urban areas to combat these impacts, however, their uptake has been limited. This study answers the question of whether green wall technologies are a suitable technology for instilling sustainability into major infrastructure projects. This was achieved by comparing available green wall systems, conducting interviews with leading industry professionals and developing a case study on the possible areas of implementation of green wall technologies within a major multi-billion dollar infrastructure project. The overall benefits and constraints are presented, with insights into how these systems may contribute to sustainability rating tools for infrastructure projects.

“…The wind speed in the wind tunnel was adjusted with the inverter and measured with a TSI 9545 anemometer. The wind speed was maintained at 5,6,7,8,9,10,11,12,13,14,15,16,17,18,19, and 20 m s −1 , with each wind speed run for 10 min. After that, an electronic scale was used to measure the mass of the residual coal powder in the two surface dishes.…”

“…[4][5][6] In areas where miners simultaneously undertake cutting, transfer, and stage loading operations, the instantaneous total dust concentration in certain coal mines can even reach 4000-6000 mg m −3 . [7][8][9] The aforementioned dust concentrations far exceed the national standard. [10][11][12] Pollution resulting from dust dispersion also constitutes a severe issue during the outdoor storage and transportation of coal.…”

Development and Performance Characterization of a Hybrid Dust Suppressant Based on Sodium Ligninsulfonate Modification

et al. 2020

A naturally occurring macromolecular material (sodium ligninsulfonate) is mixed with acrylic acid to perform grafting copolymerization and generate a sodium ligninsulfonate–acrylic acid graft copolymer. The chemical structure of the product is characterized based on infrared spectroscopy. Using viscosity and surface tension as indicators, the optimal ratio of wetting agents and coagulants is selected for auxiliary materials to prepare a novel hybrid dust suppressant customized for coal mines. The results indicate that, compared with spraying with water alone, this dust suppressant enhances the average anti‐weathering performance of coal samples by 28.34%, 30.13%, and 43.40% at wind speeds of 5–10, 11–15, and 16–20 m s−1, respectively. The hybrid dust suppressant can keep the weathering rate of dust to less than 40% at a wind speed of 19.3 m s−1 (i.e., Beaufort scale 8). High‐resolution scanning electron microscopy shows the dust suppressant has a good curing effect. Finally, coal quality analysis experiments show the dust suppressant does not reduce coal quality.

“…This shows that cleaner production has become an important choice for global sustainable development. Until now, existing research on cleaner production focuses on the analysis of the relationship between environmental pollution and production (Lu et al, 2017), cleaner production efficiency measurement (Zulfiqar et al, 2017;Liu et al, 2020), cleaner production improvement (Zulfiqar et al, 2017) and related policy evaluation (Leroy and Crabb, 2012). That is, existing studies mainly focus on the causes of pollution under policy control and provide policy recommendations.…”

We investigate a single-cycle product supply chain with one retailer and one supplier in a game model, where the supplier is the leader and the retailer is the follower. By innovatively introducing cleaner production fraudulent income perception factor into the game model, we studied the mechanism of the effect of enterprise social responsibility and environmental awareness on cleaner production fraud. The results showed that the value of cleaner production fraudulent income perception factor will affect the enterprise's choice of differentiation strategy. When the enterprise's sense of social responsibility is weak, i.e., the fraudulent income perception factor is correspondingly large, it more likely to choose cleaner production fraud. Conversely, under the constraints of high social responsibility, it more likely avoids production fraud. Regarding government supervision, a reasonable punishment for cleaner production fraud can reduce such violations to some extent. However, after the punishment reaches a level, the efficiency of supervision beginning to decline. In views of that, improving enterprise social responsibility through institutional reform is a more effective way to reduce cleaner production fraud. To contribute to a healthy competitive market environment, government supervision should establish a feedback mechanism, and make timely adjustments.
