The ongoing global climate change and the associated environmental degradation pose a threat to Europe and the rest of the world. Raw materials and energy are required to produce building materials, which are used for construction purposes. Resulting buildings and structures generate waste during construction, operation, and demolition, and they emit potentially harmful substances. Thus, the key to achieving climate goals is to support low-emission materials and technologies in the construction sector, significantly impacting the environment. In the European Union, building materials are not yet subject to mandatory sustainability assessment during the assessment and verification of constancy of performance (AVCP). Objective evaluation of construction materials’ environmental impact requires it to be carried out based on production data on an industrial scale. This article presents the environmental impact of premixed gypsum-based plasters, commonly used in modern construction. Nine environmental indicators (global warming potential (GWP), depletion potential of the stratospheric ozone layer (ODP), acidification potential (AP), eutrophication potential (EP), formation potential of tropospheric ozone (POCP), abiotic depletion potential (ADP)-elements, ADP-fossil fuels, renewable primary energy resources (PERT), and nonrenewable primary energy resources (PERNT)) of premixed gypsum plasters based on natural and flue gas desulfurization (FGD) gypsum were estimated and discussed. Knowledge of the construction products’ environmental impact is fundamental for creating reliable databases. AVCP of construction materials in the future will use the data collected during the voluntary environmental impact evaluation.

Depletion Potential

The production of waste is increasing yearly and, without a viable recycle or reutilization solution, waste is sent to landfills, where it can take thousand to years to degrade. Simultaneously, for the production of new materials, some industries continue to ignore the potential of wastes and keep on using natural resources for production. The incorporation of waste materials in mortars is a possible solution to avoid landfilling, through their recycling or reutilization. However, no evaluation of their “sustainability” in terms of environmental performance is available in the literature. In this sense, in this research a life cycle assessment was performed on mortars, namely renders, with incorporation of industrials wastes replacing sand and/or cement. For that purpose, eight environmental impact categories (abiotic depletion potential, global warming potential, ozone depletion potential, photochemical ozone creation potential, acidification potential, eutrophication potential, use of non-renewable primary energy resources, and use of renewable primary energy resources) within a “cradle to gate” boundary were analyzed for 19 mortars with incorporation of several industrial wastes: sanitary ware, glass fiber reinforced polymer, forest biomass ashes, and textile fibers. Sixteen out of the 19 mortars under analysis presented, in all environmental impact categories, an equal or better environment performance than a common mortar (used as a reference). The benefits in some environmental impacts were over 20%.

Ordinary Portland cement (OPC) is a material that is widely used in construction. The production of OPC creates large amounts of carbon dioxide. Mortar is one of the building materials that uses cement as the main ingredient, including the use of natural sand as a fine aggregate. Therefore, to reduce the use of cement and natural materials, flue-gas desulfurization (FGD) gypsum was used instead of OPC, and water treatment sludge (WTS) was used instead of fine sand to create cement mortar. This research used both materials as ingredients in the production of cement mortar and helped to reduce waste in the environment. The objective is to study the suitable ratios of FGD gypsum and WTS in the production of cement mortar. As for the binder, FGD gypsum was used instead of OPC at 0%, 10%, 20%, 30%, and 40%. Instead of fine sand, WTS was used at 0%, 5%, 10%, and 15%. The cement mortar was tested after 7 days for compressive strength. It was found that the cement mortar made with increased ratios of FGD gypsum and WTS decreased in compressive strength.

The article presents the first results from research, which is deal with recycling of plaster boards and use of the resulting material. The research is carried out within the project MPO Trio c. FV30359 “Recyklace sádrokartonových desek a nová materiálová využití s pridanou hodnotou – GIPSRec”. The plasterboards are produced of stucco, which is calcinated of Flue Gas Desulfurization Gypsum (FGD Gypsum). There is possibility to replace a part of this stucco with recycled material. There is opportunity for saving costs for production. The question how this utilization can change the properties of the products is very important and it is necessary to find the possible improvement or deterioration. This is the objective of this research. The effect on properties was monitored on the samples which was prepared of only pure stucco and of stucco with part of recycled material. There was observed water ratio (splash test), setting times, volume changes, flexural strength, compressive strength and elasticity module.

With the emphasis of national policies on green manufacturing and the recognition of the people for green development, expanding the green assessment of products will be the general trend. In this study the life cycle assessment method was used to compile a list of resources, energy consumption and pollutant emissions during the life cycle of typical ordinary gypsum plasterboard and functional phase-change gypsum plasterboard, the key environmental impact indicators of both products during the life cycle calculated, the key stages affecting the environmental performance of products analyzed and identified, and the difference in environmental impacts between phase-change gypsum plasterboard and ordinary gypsum plasterboard compared and analyzed, for guiding the selection of green building materials and the development of ecological building materials. The results show that the global warming potential of phase-change gypsum plasterboard is 3.42 kgCO2 equivalent/m2, the non-renewable resource depletion potential is 2.25×10-5 kgSb equivalent/m2, the respiratory inorganic is 1.97×10-3 kgPM2.5 equivalent/m2, the eutrophication is 1.21×10-3 kgPO43- equivalent/m2, and the acidification is 9.47×10-3 kgSO2 equivalent/m2. Compared with ordinary gypsum plasterboard, the phase-change gypsum plasterboard shows the biggest increase by 874.03% in non-renewable resource depletion potential. The major environmental impact of ordinary gypsum plasterboard in the life cycle is mainly from energy use, and the transport process is the main stage of eutrophication. The use of phase-change materials in the phase-change gypsum plasterboard is the main stage causing environmental impact.

The uncertainty of long-term bonding strength of flue gas desulfurization building gypsum and cement based construction materials is the major issue impeding the application of flue gas desulfurization building gypsum in construction. A polymer cement mortar is suggested to get high bonding quality with flue gas desulfurization building gypsum. Long-term bonding observation has been carried out to verify the bonding performance of suggested polymer cement mortar with flue gas desulfurization gypsum. The results show that the bonding strength is up to 3.0MPa, and the bonding between them is durable.

The purpose of this study was to deduce the major construction wastes to be managed using environmental impact assessment for construction wastes generated in the construction phase. To accomplish this, the amount of construction waste discharged in the construction phase was analyzed using loss rate and weight conversion factor in the Standard of Estimate for Construction Works. Based on the result of construction waste generation deduced, major construction wastes were extracted with consideration on 6 comprehensive environmental impacts including potential, abiotic depletion potential, acidification potential, eutrophication potential, ozone depletion potential, and photochemical ozone creation potential. As a result, 5 major building materials such as concrete, concrete block, rebar, cement and polystyrene panel were deduced as major cpmstruction wastes in construction phase.

This study examines the stocks of building materials in Toronto’s in-use and annual obsolete single detached housing, to provide potential environmental benefit parameters for city scale material reuse and recycling. The material volumes of five archetypes, developed to represent typical Toronto housing, were measured and extrapolated to the city scale. Applying established criteria for reusability and recyclability, city scale reusable and recyclable stocks were determined for three environmental indicators: material volume headed to landfill, carbon dioxide emissions, and primary energy consumption. It was determined that 61-66% of the material volume in Toronto’s in-use and annual obsolete housing could be reclaimed for reuse/recycling, and was mostly composed of masonry, concrete, and framing lumber from houses built from 1930-1960. Additionally, annual obsolete reusable materials represented an embodied carbon of 2,287-4,116 tonnes and energy of 52,883-95,189 GJ. By addressing common barriers to widespread uptake of reuse/recycling, Toronto could reap these determined potential environmental benefits.
