This work evaluates the performance of peracetic acid (PAA) for the disinfection of stormwater runoffs contaminated by domestic sewage with the objective of using the collecting systems as contact reactors for in-situ disinfection. PAA is increasingly being used as a substitute for chlorination in the disinfection of wastewaters because of its rapid degradability and the absence of chlorinated organic by-products. In Brazil, and despite the adoption of the separator system in sewage systems, there is a large amount of domestic effluents that are piped directly into the stormwater systems, contributing to the contamination of water bodies. The efficiency of the disinfection of Escherichia Coli was evaluated by applying different doses (2, 5 and 10 mg.L-1) of PAA with short contact times (2, 5 and 10 minutes) in real stormwater samples collected at three different points of the stormwater system of the city of Rio de Janeiro. Trials were performed simulating the conditions and flow times available in the stormwater sewers. The results were excellent, with removals up to 5 log units with 10 mg.L-1 peracetic acid and 2 minutes contact time. Where there was available a contact time of at least 5 minutes, a dose of 5 mg.L-1 was sufficient.

The development of urban cities increases the amount of construction and demolition waste, such as ceramic materials, mainly clay bricks, and consequently, generates cost for the management and environmental disposal due to the few routes to recycle or reuse them. Here, it is proposed a new approach to reuse clay bricks waste (CB) composed by red ceramic as a reinforcement filler to natural rubber (NR) composites. It was verified that the residue is mostly composed of silicon, which is a filler widely used in rubber industry as SiO2, to mechanically reinforce composites. Tensile strength showed an increment around 16% when 20 phr of CB waste was added to the natural rubber (reaching 12,4 MPa). In addition, composites with 10 phr of waste showed great abrasion resistance and the hardness property increased as CB waste was added. The results indicate that the residue can be used as a possible filler in natural rubber products.

The modern urban planning is focused towards encouraging pedestrian movement by ensuring their safety and comfort during the walk. Further, COVID-19 pandemic has abruptly obstructed our normal way of life that includes of our local as well as global transport systems. There is greater need of making the public places more pedestrian friendly with the provision of appropriate walking and cycling networks, which can tackle the social distancing issues. This paper presents a novel approach to quantitatively analyze the efficiency of present urban pedestrian streets in maintaining social distancing among pedestrians. The survey research techniques, GIS tool and technique, statistical techniques, and space syntax methods are implemented and tested for evaluating present scenario of the pedestrian movement in relation to the urban layout, in the case of Main-Market Street of Hamirpur town of Himachal Pradesh, India. The regression and correlation analysis is performed between outcomes of axial and segment analysis to establish the interrelation among spatial structure and behavioral phenomena. This paper is an attempt to generate the need of rethinking the pedestrian planning process with more holistic approaches to achieve sustainable urban environment.

The sharp increase in the utilisation and demand of construction materials across the world, especially in road, pavements and transportation sectors has resulted in an unsustainable surge in the amount of carbon emissions. This study investigated the use of low-carbon materials in permeable pavements systems (PPS) and the effects of various low-carbon engineered materials on the mechanical, absorption and infiltration performance of PPS according to relevant standards. This was achieved by the critical analysis of four (4) different materials (recycled grit, recycled glass, recycled rubber) and comparing their performance with normal materials used in conventional pavements. The four materials were implemented into concrete mixes of the permeable pavers and embedded in various layers and sub-sections making up the permeable pavement structure. As a result, the outcome required of this research is to find which mix of concrete blocks (permeable pavers) perform the best when tested for absorption and compression and which permeable pavement works best when tested for infiltration. Compression test was utilised to establish the maximum allowable compressive force, while the absorption test identified the concrete mix that could hold the least amount of water when soaked in water for 24 hours. This was expected to reduce the possibility of breakage of the concrete blocks. Finally, the infiltration test was employed to establish the best performing pavement material based on the rate and amount of infiltration of a fixed volume of effluent. The results obtained from the laboratory tests shows improved performances of the pavements embedded with recycled materials. Therefore, it can be recommended that the use of recycled materials in the development of low-carbon permeable pavements, possesses the ability to perform efficiently in comparison with conventional PPS in the construction and built environment sectors.

The road transport sector plays a vital role in economic development and vehicle numbers are growing. It provides a set of services to meet the different demands of travel and it is a necessity for human civilization. However, although it is an essential element in regional development schemes, it generates negative externalities, thus constituting one of the most important sources of environmental pollution. This paper aims to develop modelling vehicle emissions, especially, the HC, CO and NOx based on experimental speed profiles, acceleration and technical parameters related to the used vehicle. This helps to determine and study vehicle emissions factor related to different pollutant. Two methods are used to develop two different empirical models: the multiple regression and Artificial Neural Network (ANN). The developed approach was applied to two types of vehicle with different technical characteristics. It was observed that the multiple linear regression method allows to predict vehicle emissions with a coefficient of determination between 0.723 and 0.921 but the ANN model can predict exhaust gases with a correlation coefficient in the range of 0.95–0.99. Simulation results demonstrate the efficiency and superiority of the ANN tool to estimate vehicle emissions compared to multiple linear regression approach.
