“…It is also important to emphasize the tough financial targets that many companies have in terms of material cost decrement and that provoke, under a pure economic assessment, that "greener materials" shall hardly ever defeat conventional ones (e.g., "green vs. conventional steel" [67]).

Industries are nowadays not only expected to produce goods and provide services, but also to do this sustainably. What qualifies a company as sustainable implies that its activities must be defined according to the social and ecological responsibilities that are meant to protect the society and the environment in which they operate. From now on, it will be necessary to consider and measure the impact of industrial activities on the environment, and to do so, one key parameter is the carbon footprint. This paper demonstrates the utility of the LCI as a tool for immediate application in industries. Its application shall facilitate decision making in industries while choosing amongst different scenarios to industrialize a certain product with the lowest environmental impact possible. To achieve this, the carbon footprint of a given product was calculated by applying the LCI method to several scenarios that differed from each other only in the supply-chain model. As a result of this LCI calculation, the impact of the globalization of a good’s production was quantified not only financially, but also environmentally. Finally, it was concluded that the LCI/LCA methodology can be considered as a fundamental factor in the new decision-making strategy that sustainable companies must implement while deciding on the business and industrial plan for their new products and services.

“…The energy sector, the iron and steel industry, along with heavy industry and petroleum refineries [1], are by far the largest emitters of CO 2 emissions, due to their high fuel and energy demand. The steel industry accounts for between 7% and 11% [1][2][3][4][5][6][7] of global CO 2 emissions as a result of steelmaking, and China is responsible for 50% of these GHGs [7], due to their heavy reliance on coal. The increased use of coal in energy generation, due to imposed oil and gas shortages, was found to be the main factor [1,8] driving up global energyrelated anthropogenic CO 2 emissions by over 2 billion tonnes, their largest ever rise in absolute terms.…”

Global energy market price volatility and an upward trajectory of prices per unit of electricity have sent all industrial sectors and many economies to the brink of recession. Alongside the urgent need for decarbonisation of all industries, achieving a globally higher level of energy independence across all sectors seems imperative. A multi-disciplinary approach with a proposed system of CO2 emissions reduction and capture technologies has the potential for short-term emissions reduction to near-zero in the steel industry—although some of the mechanisms can be implemented across most heavy industries. The findings of this research show a CO2 emissions reduction of ~30% from 977 t of CO2 to 684 t in one single blast furnace production cycle (based on 330 tonnes of liquid iron production capacity, with the mean of 2.1–3.2 tonnes CO2/t of steel and chemical reactions emissions applied), by switching the electricity provider for operating the electric heaters to providers generating energy exclusively from renewable sources. Replacing coal with biomass and adding post-combustion capture units to the blast furnace operation, will add carbon neutrality into the process—resulting in CO2 emissions reduction to near-zero. Carbon capture from biomass utilisation (BECCS) will add the benefit of carbon-negative emissions to the cycle. Simultaneously, energy-saving and process improvement measures implementation (up to 60% efficiency increase), excess heat recovery <30% of energy savings, and retrofitting renewable energy technology resulted in an energy independence of 88%. Engineering solutions, partly subsidised in the UK, are readily available for implementation in the iron and steel manufacturing industry.

“…This process is divided into two main parts: iron production in a blast furnace (BF) and steel production in a basic oxygen furnace. 70% of CO 2 emissions are produced during the BF processes [14]. Approximately 65% of the total steel produced in the world is produced using this method.…”

“…Industries are responsible for 21% of all CO 2 emissions, which includes cement and steel production. 30% and 26% of all carbon emissions are released in steel and cement production processes, respectively, which means that more than half of the CO 2 emissions of all indus-trial activities are caused by steel and cement production [14]. High temperatures, 1,400 °C for glass; 1,200-2,400 °C for carbon, are required during producing (FRP) [15].…”

Strengthening and rehabilitation have been widely implemented for many years to extend the service life of reinforced concrete structures. The paper begins with a comprehensive review of the fiber-reinforced polymers (FRP) utilization on strengthening particularly over the traditional materials formerly used in practice with respect to materials, manufacturing, operation, construction, and maintenance phases, as well as the engineering and environmental performance of such materials. Carbon and Glass FRP, the most frequently used strengthening materials, are particularly designated in the study and are employed to conduct an environmental performance evaluation using the previously published data in the literature. The paper then investigates the punching shear strength of flat slab-column connections strengthened with externally bonded FRP by means of a nominated database comprising 57 number of data points harvested from the recent literature. The database is used in the evaluation of the test data with TS 500 code equations and the recent modification of Chen and Li. The study enabled the key factors affecting the punching shear strength of such connections to be emphasized and highlighted the fact that the TS 500 code equations fall conservative in predicting the punching shear strength of slab-column connections strengthed with FRP. The study is novel as it provides a comprehensive review of the FRP as a strengthening material with regards to environmental sustainability and also provides an insight into the structural implications of this material by evaluating the current TS 500 code provisions and recent modifications.
