The first life cycle assessment (LCA) of injection-molded composites made of low-density polyethylene (LDPE) and polypropylene (PP) reinforced with calcium-rich flue gas desulfurization (FGD) gypsum and marble waste is shown in this work. The life cycle phases of the manufacturing of polymer composites were assessed using the methodological framework of IS/ISO 14044:2006. Midpoint indicators were evaluated by the ReCiPe method. To determine the composition, the physicochemical properties of the used FGD gypsum and marble waste were analyzed to ensure utilization in subsequent composite materials. American Society for Testing and Materials (ASTM) standards were followed for mechanical testing to check the quality of the developed composites. The flexural strength of the developed polymer composites was higher than that of pristine specimens with a 20–80 wt % filler concentration. Using the openLCA software and ecoinvent database, a cradle-to-gate LCA was performed for the developed composites. The global warming potential of the MW-PP composites is 1.01–1.06 times less than those of the other developed reinforced composites. The results of the present research are useful for creating environmentally friendly technologies, particularly the injection-molding practice.

“…Pervious concrete is a novel and sustainable pavement material, which generally consists of coarse aggregates, cement, and water 1 , 2 . Pervious concrete (PC) pavement has many functional and environmental benefits in urban settings because it facilitates stormwater infiltration, reduces surface runoff, mitigates the heat island effect, etc 3 – 6 .…”

Pervious concrete (PC) pavement has been widely accepted as a green infrastructure but is prone to clogging. This study comparatively investigated sand and clay clogging mechanisms of PC and vertical sediment distributions of sand-clogged and clay-clogged PCs. Clay and three sizes of sand were used to clog PC under two exposure methods (no drying and drying). X-ray computed tomography (CT) was used to scan the clogged samples before and after 30 pressure washing cycles. The clogged permeability and permeability after each washing cycle were measured. The clogging patterns of sand depend mainly on sand particle sizes relative to PC pore sizes. The applied fine sand, coarse sand, and medium sand cause easy-passing clogging, surface clogging, and full-depth clogging, respectively. After clay clogging, more than 77% of the total retained clay occurs within the vertical region 24–72 mm below the sample surface; the most clogging (the lowest-permeability layer) occurs at a depth of approximately 48 mm. The dried clay retained within the region 40–120 mm below the surface (especially within the lowest-permeability layer) is hard to wash away because the drying process increases the cohesion of internal clay particles and clay adhesion to the rough, tortuous pore wall of PC. The clogged normalized permeability of 0.154 and permeability recovery ratio of 4.91% in dried clay-clogged samples are lowest among all the samples. However, pressure washing readily washes away the retained undried clay. Accordingly, it is recommended that pressure washing is used to eliminate the clogging effect of dried clay before hot, sunny exposure conditions dry the retained clay. This study provides evidence for developing effective pavement maintenance strategies.

“…One of the most applied methodologies is the Life Cycle Assessment (LCA) and its variants of cost, Life Cycle Cost Assessment (LCCA), and energy, Life Cycle Energy Assessment (LCEA). Some studies have evaluated the LCA [37][38][39][40], energy-related analysis [39,41] and LCCA [39,40,42,43] of concrete or asphalt permeable pavement systems or coatings. Antunes et al [44], for example, conducted a systematic review of the LCA of permeable pavements, whose conclusions corroborate the need for maturation of the technique.…”

Permeable pavements have been the subject of numerous studies in recent decades. The possibility of dissipating stormwater more smoothly and generating numerous benefits to the environment and users makes the use of permeable pavements an excellent possibility of integration into sustainable and resilient water management systems in cities. In Brazil, numerous studies on the quantity and quality of infiltrated water, permeability of the coating, clogging, environmental burden, and feasibility, among other characteristics, have been researched. Within this theme, the Federal University of Santa Catarina (UFSC) has contributed with ten papers in the research of permeable pavements in the last six years, which address various topics about the effectiveness and applicability of permeable pavements. This paper reviews the studies conducted at UFSC on permeable pavements and discusses the different results within the main issues found. In general, the selected documents addressed seven themes in the studies: potential for potable water savings, clogging, quantity and quality of the water infiltrated into the pavement, Life Cycle Assessment (LCA) and its variants, and hydraulic and structural design details. More specifically, many selected papers assess the potential use of stormwater harvested through permeable pavements in non-potable uses of buildings. The possibility of aligning the benefits of green infrastructure with the rational use of water expands the advantages of the system and can help prevent future water scarcity, as well as reduce the environmental impacts of paving.
