Sustainability (Organisational Strategy)

Business is increasingly employing sustainability practices, aiming to improve environmental and social responsibility while maintaining and improving profitability. For many organizations, profit-oriented business models are a major constraint impeding progress in sustainability. A formally defined ontology, a model definition, for profit-oriented business models has been employed globally for several years. However, no equivalent ontology is available in research or practice that enables the description of strongly sustainable business models, as validated by ecological economics and derived from natural, social, and system sciences. We present a framework of strongly sustainable business model propositions and principles as findings from a transdisciplinary review of the literature. A comparative analysis was performed between the framework and the Osterwalder profit-oriented ontology for business models. We introduce an ontology that enables the description of successful strongly sustainable business models that resolves weaknesses and includes functionally necessary relationships.

[Since this research was completed, the practitioner visual design tool (the Strongly Sustainable Business Model Canvas) that is conceptually "powered by" the the Strongly Sustainable Business Model Ontology, has been further refined to become the Flourishing Business Canvas - see www.FlourishingBusiness.org for the most recent practice and developments].

Urban Sustainability in Theory and Practice responds to the crises of sustainability in the world today by going back to basics. It makes four major contributions to thinking about and acting upon cities. It provides a means of reflexivity learning about urban sustainability in the process of working practically for positive social development and projected change. It challenges the usually taken-for-granted nature of sustainability practices while providing tools for modifying those practices. It emphasizes the necessity of a holistic and integrated understanding of urban life. Finally it rewrites existing dominant understandings of the social whole such as the triple-bottom line approach that reduces environmental questions to externalities and social questions to background issues. The book is a much-needed practical and conceptual guide for rethinking urban engagement.

=Purpose
This conceptual paper alerts the reader to the urgent need to address the most pressing challenge and opportunity of the 21st century, namely leadership that enables flourishing for all forever.

=Design/methodology/approach
This concept paper suggests a heuristic for the reader and supplies a working model of leadership as enabling function for flourishing that arises from a survey of the literature around leadership development as well as a brief review of the literature on flourishing.

=Findings
The paper highlights the reality that there are, as yet, only a small number of organizations and leadership that have conceptualized and implemented the notion of flourishing by design and that a great deal more research and implementation needs to occur to prove the validity of the model.

=Research limitations/implications
We need to undertake quasi-experimental research in which leadership development praxis incorporates the element of flourishing by design and then action research through which the outcomes can be measured, modified, and ongoing improvements iterated into the organizational design.

=Practical implications
This paper suggests a different mindset and skillset for leadership, and by implication, leadership development. Our ongoing research into "Seeking Best Methods for Leadership Development," through our Round 1 Delphi survey has uncovered the elements of Human Capital, Social Capital, Structural Capital, and Self Leadership, as core elements desired by global CEO's as necessary for an effective leadership development program. What we did not probe for, and need to probe for, is the element of "Flourishing Capital," or the degree to which the leadership might be developed to serve as enabling function for flourishing for all forever

=Originality/value
The paper highlights the reality that there are, as yet, only a small number of organizations and leadership that have conceptualized and implemented the notion of flourishing by design and that a great deal more research and implementation needs to occur to prove the validity of the model.

While many studies in the field of environmental communication have focused on exploring the environmental impact of social media, this research paper takes a different turn. It investigates, through a qualitative content analysis, 391 websites that support and provide green hosting services. This study is considered the first in the field that aims to examine in-depth how these green websites tend to communicate their green services. Therefore, its contribution is to enhance the relevant bibliography and present more insights regarding green websites and sustainability. The results showed that most of the websites were trying to highlight the positive impact their services will have on the environment. In addition, many websites tried to educate their consumers concerning sustainable development and make them part of a broader green cultural tradition. Nevertheless, on many websites, green hosting seemed a supplementary factor for choosing the company’s services.

District heating networks are commonly addressed in the literature as one of the most effective solutions for decreasing the greenhouse gas emissions from the building sector. These systems require high investments which are returned through the heat sales. Due to the changed climate conditions and building renovation policies, heat demand in the future could decrease, prolonging the investment return period. The main scope of this paper is to assess the feasibility of using the heat demand – outdoor temperature function for heat demand forecast. The district of Alvalade, located in Lisbon (Portugal), was used as a case study. The district is consisted of 665 buildings that vary in both construction period and typology. Three weather scenarios (low, medium, high) and three district renovation scenarios were developed (shallow, intermediate, deep). To estimate the error, obtained heat demand values were compared with results from a dynamic heat demand model, previously developed and validated by the authors. The results showed that when only weather change is considered, the margin of error could be acceptable for some applications (the error in annual demand was lower than 20% for all weather scenarios considered). However, after introducing renovation scenarios, the error value increased up to 59.5% (depending on the weather and renovation scenarios combination considered). The value of slope coefficient increased on average within the range of 3.8% up to 8% per decade, that corresponds to the decrease in the number of heating hours of 22-139h during the heating season (depending on the combination of weather and renovation scenarios considered). On the other hand, function intercept increased for 7.8-12.7% per decade (depending on the coupled scenarios). The values suggested could be used to modify the function parameters for the scenarios considered, and improve the accuracy of heat demand estimations. Abstract This study aims to examine the nonsterilized fermentation conditions for coproduction of pectinases and lipase enzymes using several fruit wastes as an energy source. Thermophilic fungal strain, Penicillium expansum CMI 39671 was used as a fermenting strain. The effect of process conditions including; nitrogen sources, pH, temperature, time and moisture contents, on the production of both enzymes were studied. The highest activities of pectinase and lipase (2817, 1870 U/g dry substrate) enzymes were found with orange peel feedstock, whereas the lowest activities of 1662 U/g and 1266 U/g were found with banana peel and papaya peel feedstocks respectively. Overall, pectinase showed higher enzymatic activities than lipase enzymes, both having similar increasing and decreasing trends, at all studied conditions. The optimum process conditions of peptone as a nitrogen source, pH 7, 40°C, 5 days and 70% moisture contents, were found to show highest enzymatic activities for both enzymes. The orange peel feedstock showed no significant difference in both enzymes' activities at sterilized and nonnotarized process conditions. Pectinase and lipase enzymes showed (13791 U/g) and (8114 U/g) for sterilized and (14091 U/g) and (8324 U/g) for nonnotarized process conditions respectively. In addition, the fungal strains also produce bacteriocin-like compounds that could inhibit microbial growth. These findings will help to design and develop robust, cost-effective and less energy intensive enzyme production processes and consequently an efficient fruit waste to energy system through open fermentation.

In this research, an integrated system for sustainable agriculture and environment was designed and built at the experimental farm of Palestine Technical University. The system included: a) Hydroponic unit, b) Aquaponic unit, c) Pilot plant for wastewater treatment, d) Home composter. Lettuce crop was used throughout the research to compare its yield under different agricultural systems. In this regard, lettuce was planted in hydroponic and aquaponic systems, whereas, conventional cultivation of the same crop was performed using direct irrigation with hydroponic solution, direct water effluent from fish rearing tank and effluent from wastewater treatment plant, in addition to control trial using fresh water and fertilizers. Lettuce production in each trial was evaluated using different parameters. The obtained results showed that hydroponic system is the most efficient one, where fast production with little resources could be achieved. Nevertheless, and even acceptable results were obtained in aquaponic system, it was clear that more attention should be applied as fish is affected by the surrounded ambient factors, mainly the temperature. Also, the wastes produced by fish may need more time to be degraded, or does not contain all nutrients needed by plants, thus hinder their growth. Both systems used around 80% less water than growing in soil, which is important especially with the scarcity of water resources for agricultural sector.

In a world increasingly faced with, and divided by, regional and global crises, resilience has emerged as a key concept with significant relevance for tourism.

A paradigmatic shift is taking place in the long-term planning of tourism development, in which the prevailing focus on sustainability is being enhanced with the practical application of resilience planning. This book provides a critical appraisal of sustainability and resilience, and the relationship between the two. Contributions highlight the complexity of addressing social change with resilience planning in a range of tourism contexts, from islands to mountains, from urban to remote environments, and in a range of international settings. Case studies articulate how tourism is both an agent of social change and a victim of larger change processes, and provide important lessons on how to deal with increasingly unstable economic, social and environmental systems.

This book is the first to specifically examine social change and sustainability in tourism through a resilience lens. This much-needed contribution to the literature will be a key resource for those working in tourism studies, tourism planning and management, social geography, and development studies, among others.

The concept of circular economy (CE) has recently gained momentum in the political, scientific, and economic debate, especially in China and Europe. As a result, organizations and scholars have started to establish different sets of principles for its adoption. For this reason, it is important to identify and assess the differences and similarities among existing sets of CE principles, and how organizations and individuals understand and translate them into practice. In this paper, we firstly present a brief review and analysis of the coherence among six existing sets of principles. Our analysis finds that, despite the mixed degree of coherence, all sets describe the necessity to implement CE principles at all levels of a company. We then present the results of an in-depth qualitative survey that investigates how 19 key informants representing small, medium, and multinational companies based in China understand and carry out the CE principles laid out by the BSI standard BS 8001:2017; how these principles can transform the culture and processes of these companies; and what are the opportunities and threats that such transformation can bring. Results describe a good awareness and knowledge of the CE principles and an optimistic outlook concerning their adoption. At the same time, numerous barriers and threats that the implementation of these principles might entail are presented. Overall, respondents confirm the complexity of implementing the principles of the CE in an integrated and consistent way in the management and strategies of Chinese companies and highlight the challenges that might arise during their implementation.

The explosion of the BP-leased Deepwater Horizon and subsequent oil spill stands as an indictment not just of our national energy priorities and environmental law enforcement; it equally represents a failure of Anglo-American corporate law and what passes for corporate social responsibility in business today. Using BP and the disaster as a compelling case study, this Article examines green marketing and corporate governance and identifies elements of each that encourage firms to engage only superficially in corporate social responsibility yet trumpet those efforts to eager consumers and investors. The Article then proposes reforms and protections designed to increase corporate social responsibility, root out greenwashing, and recognize liability for corporate social responsibility frauds on consumers and investors. One of these protections derives from the newly enacted Dodd-Frank Act, whose Bureau of Consumer Financial Protection could play a leading role in policing fraudulent claims of corporate social responsibility.

Biomass pyrolysis is a promising renewable sustainable source of fuels and petrochemical substitutes. It may help in compensating the progressive consumption of fossil-fuel reserves. The present article outlines biomass pyrolysis. Various types of biomass used for pyrolysis are encompassed, e.g., wood, agricultural residues, sewage. Categories of pyrolysis are outlined, e.g., flash, fast, and slow. Emphasis is laid on current and future trends in biomass pyrolysis, e.g., microwave pyrolysis, solar pyrolysis, plasma pyrolysis, hydrogen production via biomass pyrolysis, co-pyrolysis of biomass with synthetic polymers and sewage, selective preparation of high-valued chemicals, pyrolysis of exotic biomass (coffee grounds and cotton shells), comparison between algal and terrestrial biomass pyrolysis. Specific future prospects are investigated, e.g., preparation of supercapacitor biochar materials by one-pot one-step pyrolysis of biomass with other ingredients, and fabricating metallic catalysts embedded on biochar for removal of environmental contaminants. The authors predict that combining solar pyrolysis with hydrogen production would be the eco-friendliest and most energetically feasible process in the future. Since hydrogen is an ideal clean fuel, this process may share in limiting climate changes due to CO 2 emissions.
