“…The life cycle impact assessment performed was based on the IMPACT 2002+ methodology, which is very frequently used among researchers and environmentalists (see [ 35 , 36 ]). Following midpoint indicators were used to compare the particular mixtures studied: carcinogens (CA), non-carcinogens (NCA), respiratory organics (RO) and inorganics (RI), aquatic (AE) and terrestrial ecotoxicity (TE), terrestrial acidification/nitrification (TA/N), aquatic acidification (AC) and eutrophication (AEU), land occupation (LO), mineral extraction (ME), non-renewable energy (NRE), ionizing radiation (RI), ozone layer depletion (OLD), and global warming (GW).…”

Production of concrete is connected to extensive energy demands, greenhouse gases production or primary sources depletion. Reflecting current economical, social, or environmental trends, there is strong pressure on mitigation these requirements and impacts. The exploitation of secondary- or waste materials in production processes has therefore a great potential which is not related solely to binders but also to fillers. In this light, this paper aims at thorough investigations of concrete mixtures with crushed concrete pavements as partial or full replacement of natural coarse aggregates. The research combines experimental techniques to quantify the influence of the substitution on basic physical, mechanical, and heat/moisture transport/storage parameters. The experimental data obtained are further exploited as input data for computational prediction of coupled heat and moisture transport to assess the influence of the aggregates substitution on hygrothermal performance of the built-in concretes. In the last step, the environmental impacts are assessed. Since the changes in the hygrothermal performance were found to be insignificant (i), the compressive strength were improved by up to 25% (ii) and most of the environmental impact indicators were decreased (iii) at the same time, the findings of the research presented predeterminate such a reuse strategy to wider application and use.

“…One of the latest, complex approaches including the economic, social, and environmental dimensions of sustainability [18,64] is the Triple Layered Business Model Canvas (TLBMC), which interprets the original BMC as the economic dimension of sustainability, adding two additional layers to it, the environmental layer, representing the life-cycle approach, and the social layer, representing the stakeholder approach [18,64]. The practical application of this model has already been tested in many sectors [18,[65][66][67][68][69][70][71]. Although we consider the new variations of the tool to be promising for the future, our goal is to specifically use the original BMC [58] which is a widespread and well-known business modelling tool that can stress the importance of sustainability issues in a transparent, distinct way even for mainstream economists, bankers and decision-makers.…”

Business Model and Principles of a Values-Based Bank—Case Study of MagNet Hungarian Community Bank

2021

View full text Add to dashboard Cite

The 2020–2021 global pandemic has brought significant changes to social and economic life. Companies must begin to rethink their business models and values to meet these new challenges. Given the process of intermediation, which has an indirect and catalytic impact, banks have a responsibility and opportunity to transform the economy by, for example, lending to projects that encourage decarbonization and/or green energy. The purpose of this paper is to examine the MagNet Hungarian Community Bank’s approach as a values-based bank in order to compare how the operation of the bank differs from that of traditional ones—even if these apply the Corporate Social Responsibility approach. The findings of an exploratory study of MagNet’s responsible and sustainable way of doing business can help other sectors and companies cope with the global crisis and be a part of the transition to an inclusive, fair, and decarbonised economy. The data for this study were collected using semi-structured interviews with eleven bankers and three customers of MagNet Bank in 2019, as well as bank documents. Using this information, we created a business model for the bank, using the Business Model Canvas method. Within the business model we highlighted how MagNet Bank integrates principles of the Global Alliance for Banking on Values, with the aim of truly integrating sustainability into the core of their corporate genetic makeup, instead of as a partial or insincere measure. With the projection of the models onto each other, we emphasize the role of values in the business model. The combination of the models indicates potential learning points for the further development and long-term success of the bank and serves as an example of good practices for others. This is especially relevant when considering the greater need for improved crisis and risk management due to the pandemic and for the integration of sustainability considerations into business operations which have increased the impetus in the financial sector towards sustainability.

“…The value proposition element is the most important key factor in the marine waste processing business. This element can explain the benefits created by companies in selling products to their customers and why they should choose that company over other companies that provide similar products or services [37]. In marine waste processing companies, the value proposition is the element that gives what customers will get in this business, namely providing raw material products from waste in the sea and coastal areas.…”

“…The objective of the environmental layer is to ensure that the full life cycle of a product or service is considered, when a new business is launched, with an emphasis on environmental impact. This objective is based on Life Cycle Analysis (LCA) which is important to know the mapping of environmental impacts (e.g., carbon and water footprint) originating from a product or service over the entire life cycle [37,38]. With this layer, the company will easily identify negative and positive externalities in the environment generated by the company's activities.…”

Aims: The shift from linear to circular business models is becoming increasingly necessary at the environmental level. There are many ways to make business and the environment an inseparable unit, one of which is by promoting the circular economy business model. Methodology: This study focuses on the Triple Layer Business Model Canvas approach to apply the circular economy concept by using the example of a marine waste processing company. Results: The results showed that the mapping of the waste processing business model with the TLBMC approach can be described as a whole, the sustainable value of the company in three integrated layers, namely the economic layer, the environmental layer, and the social layer. Despite the limitations resulting from this study but the findings in this study can be adapted to other waste processing companies.
