This could lead to the greater utilization of POFA in concrete and, subsequently, could be useful in protecting the environment by minimizing volume of waste disposed on the wasteland and minimizing emission of greenhouse gases that released during cement production, besides contribute to cost saving which could somehow contribute towards the sustainability of the concrete industry.
A significant advantage is the conversion of chemical into electrical energy and vice-versa, minimizing the amount of waste heat.
Across Harvard departments and Schools are focused on minimizing the amount of waste they produce by reusing equipment and materials that are no longer needed.
This approach could lead to the significant utilization of PWAs in concrete, which could, thus, help in protecting the environment by minimizing the volume of waste disposal.
To mitigate this environmental damage, is possible to use waste from other sectors to reduce raw material or by minimizing the generation of waste with materials of satisfactory durability.
The aim of this paper is to develop and apply several criteria for the building sector that help decision making at the design and construction stages, thereby allowing the selection of sustainable building materials, reducing the environmental impact of the materials used, minimizing the amount of waste generated, and increasing the percentage of this waste that is recycled.
Nowadays, educational institutions, as is the case with many other places, focus on minimizing the amount of waste generated while maximizing the extraction of value-added products from these wastes.
Harvard is focused on operating an efficient campus that incentivizes reuse and minimizes the amount of waste we produce.
Land-based closed systems minimize the amount of waste and nutrients expelled to the environment, eliminate fish escapes and limit the spread of disease; but pumping the water through them requires a great deal of energy, and the wastewater must still be disposed of properly.
Also, the approach is environmentally friendly and minimize the production of waste wherein necessitates aqueous quenching and neutralization steps to remove an acid and washing out the surfactant is not required, and thus effectively reduces the emission of hazardous waste and pollutants and maintains economic viability of the process.
The adoption of low activation materials, while important for reducing the radiotoxicity of the most active components, should be done as part of a strategy that also minimizes the volume of waste material that might be categorized as radioactive, even if lower in level.
