If you live in an apartment or a house, you will notice that your home has different rooms separated by walls. A plant is just like your home, except there are many small rooms, called cells. Plant cells, like rooms, are also separated by cell walls. Cell walls are unique and are not found in animal cells. In a building, if you want to turn one large room into two small rooms, you build a new wall to divide it. This is similar to how a plant cell divides into two cells during cell division. To build a wall in a building, you need to employ construction workers, design the building plan, buy building materials, and finally assembly the wall. How does the plant cell take care of these different jobs? This article explains how the cell wall is built in a plant cell during cell division.

Conventional building materials (CBMs) made from non-renewable resources are the main source of indoor air contaminants, whose impact can extend from indoors to outdoors. Given their sustainable development (SD) prospect, green building materials (GBMs) with non-toxic, natural, and organic compounds have the potential to reduce their overall impacts on environmental and human health. In this regard, biocomposites as GBMs are environmentally friendly, safe, and recyclable materials and their replacement of CBMs reduces environmental impacts and human health concerns. This study aims to develop a model of fully hybrid bio-based biocomposite as non-structural GBMs and compare it with fully petroleum-based composite in terms of volatile organic compound (VOC) emissions and human health impacts. Using a small chamber test (American Society for Testing and Materials (ASTM)-D5116) for VOC investigation and SimaPro software modeling with the ReCiPe method for evaluating human health impacts. Life cycle assessment (LCA) methodology is used, and the results indicate that switching the fully hybrid bio-based biocomposite with the fully petroleum-based composite could reduce more than 50% impacts on human health in terms of indoor and outdoor. Our results indicate that the usage of biocomposite as GBMs can be an environmentally friendly solution for reducing the total indoor and outdoor impacts on human health.

Purpose – There have been speculations as to whether environmental friendly buildings are always healthy. Using lifecycle assessment (LCA) methodology, the purpose of this paper is to investigate lifecycle relationship between building sustainability and its environmental health impacts Design/methodology/approach – In order to achieve this, a block of classroom was modelled with the aid of Revit software, and its lifecycle global warming potential (GWP) and human health impacts were analysed using green building studio and ATHENA impact estimator tools. Sensitivity analyses of the block of classrooms were then carried out by varying the building materials and energy use pattern of the original typology. The LCA was performed for seven alternative typologies that were achieved through variation in the building materials and energy use patterns. Findings – For all the eight building typologies, the study shows a direct relationship between GWPs and human health impacts. This confirms that the more sustainable a building, the less its tendency for having negative health effects on building operatives, occupants and the wider environment. Again, the more green a building in terms of its materials and energy use pattern, the healthier the building becomes. Research limitations/implications – The human health impacts was evaluated by measuring amount of particulate matter (PM2.5) produced by the buildings while environmental impact was evaluated by measuring global warming (KgCO2) potentials of the buildings throughout its lifecycle. The study has been based on the impacts of building materials and energy use patterns over the entire lifecycle of the buildings and materials used for construction. Originality/value – The study established a positive relationship between GWP of building and its human health impacts. Thus, all arguments relating to the relationship between building sustainability and health are laid to rest by the paper.

The United States Environmental Protection Agency (EPA) has labeled as “friable” those building materials that are likely to readily release fibers. Friable materials when dry, can easily be crumbled, pulverized, or reduced to powder using hand pressure. Other asbestos containing building materials (ACBM) where the asbestos fibers are in a matrix of cement or bituminous or resinous binders are considered non-friable. However, when subjected to sanding, grinding, cutting or other forms of abrasion, these non-friable materials are to be treated as friable asbestos material. There has been a hypothesis that all raw asbestos fibers are encapsulated in solvents and binders and are not released as individual fibers if the material is cut or abraded. Examination of a number of different types of non-friable materials under the SEM show that after cutting or abrasion, tuffs or bundles of fibers are evident on the surfaces of the materials. When these tuffs or bundles are examined, they are shown to contain asbestos fibers which are free from binder material. These free fibers may be released into the air upon further cutting or abrasion.
