Abstract The novelty of this paper is the focus solely on MSW collection/transport in mid-sized metropolitan regions of developing countries, using biomethane (which can be supplied by the MSW management system) an alternative fuel and different waste collection methods. The eight proposed scenarios, compared to the baseline scenario, combine diesel and biowaste, doorto-door and bring collection methods, as well as two different levels of sourceseparated collection. The results have shown if the collection vehicles use biomethane, the impacts will always be significantly lower than using diesel (between 68–98%, depending on the impact category and scenario), even accounting with the uncertainty of the results. In this particular case-study, increasing source-separated collection also reduced the transport impacts in 40–50%, as the transfer stations are closer to the recycling facilities than the landfills. This is because the fuel consumption of transport is a function of distance, so is the impact. Therefore, this study recommends: using biomethane produced from anaerobic digestion of organic waste instead of diesel to expand circular MSW management; establishing transfer stations for the municipalities located more than 25 km away from waste management facilities; expanding the collection coverage to 100%; increasing sourceseparated collection and recycling.

Abstract This paper focuses on the largely unexamined phenomenon of the developing trans-national suburban area west of Szczecin. Sadly the local communities in this functionally connected area struggle with national planning policies that are unsuitable for the region. The paper examines the impact of those processes on the border region in general and on the localities in particular. The paper investigates the consequences for local narratives and the cohesive development of the Euroregion and what position Polish and German communities took to develop the region, even without the necessary planning support. The region has succeeded in establishing grass-roots planning mechanisms which have helped to create a metropolitan-region working from the bottom up.

<p>The relationship between women, technology manifestation, and likely prospects in the developing world is discussed in this manuscript. Using India as a case study, the paper goes on to discuss how ontology and epistemology views utilised in AI (Artificial Intelligence) and robotics will affect women's prospects in developing countries. Women in developing countries, notably in South Asia, are perceived as doing domestic work and are underrepresented in high-level professions. They are disproportionately underemployed and face prejudice in the workplace. The purpose of this study is to determine if the introduction of AI would exacerbate the already precarious situation of women in the developing world or if it would serve as a liberating force. While studies on the impact of AI on women have been undertaken in developed countries, there has been less research in developing countries. This manuscript attempts to fill that need.</p>

The Impact

Abstract Tofu contains various substances that are very good when consumed to improve people’s nutrition. In addition, tofu also has good taste. The problem is that the tofu production process produces products and non-product outputs in the form of waste that is very dangerous if directly disposed of in the environment. The BOD5 content of tofu small and medium-sized enterprises (SMEs) in Sugihmanik Village ranged from 3,667-4,933 mg/L and COD 7,668-9,736 mg/L. At the same time, the TSS values ranged from 701-1,189 mg/L. The BOD5 value in the river water content is 367 mg/L. It greatly exceeds the set Threshold Value. This study aims to measure the environmental impact using Life Cycle Assessment (LCA). LCA can identify the impact of each activity based on the impact category to identify the processes that contribute significantly to damaging the environment. This study found that the cooking and frying process had the highest impact, where the climate change category was the largest. Wastewater treatment plants, biogas from the biodigester as a substitute for electricity for water pumps, rice husks, and corn cobs are expected to reduce environmental impacts.

Purpose The purpose of this paper is to extend the understanding of how internal organisational processes change in response to external demands, by investigating the changes undertaken by two Polish business schools (b-schools) in anticipation of and in response to the demands of accreditation agencies (AAs) and other powerful stakeholders. Specifically, it examines the internal research-related performance measurement (PM) system and changes in the use of performance information (PI). Design/methodology/approach The case study method is adopted, using data from publicly available documents and interviews with the faculty and management at the two schools. The data are interpreted and analysed using the neo-institutional theory. Findings Powerful stakeholders are the primary reason for changes in PM systems and the manner in which PI is used. Specifically, AAs reflect an additional layer in the PM system, allowing for a downward cascading PI effect. This also leads to a wider use of PI across different organisational levels. Research limitations/implications This study focusses on two case studies in a region still undergoing transition. Thus, this analysis could be reinforced through additional cases, different data collection methods and cross-country and between-country comparative analyses. Originality/value The changes in PM systems and particularly the use of PI are discussed in the context of Polish higher education (HE) and, more broadly, the entire Central and Eastern Europe (CEE) region. Moreover, the consideration of two b-school cases facilitates a comparative analysis of the differences in PM systems and the use of PI in the context of stakeholders’ PI needs.

Food waste is a significant contributor to greenhouse gas emissions (GHG) and therefore global warming. As such, the management of food waste can play a fundamental role in the reduction of preventable emissions associated with food waste. In this study, life cycle assessment (LCA) has been used to evaluate and compare the environmental impact associated with two composting techniques for treating food waste using SimaPro software; windrow composting and the hybrid anaerobic digestion (AD) method. The study, based on a 1 tonne of food waste as a functional unit for a case study in the State of Qatar, concludes that anaerobic digestion combined composting presents a smaller environmental burden than windrow composting. The majority of the emissions generated are due to the use of fossil fuels during transportation, which correspond to approximately 60% of the total impact, followed by the impact of composting with 40% of the impact especially in terms of global warming potential. Environmental assessment impacts were the highest in windrow composting for the acidification impact category (9.39 × 10 − 1 kg SO2 eq). While for AD combined composting the impact was highest for the human toxicity impact category (3.47 × 10 kg 1,4 − DB eq).

Different Levels

A multi-sided platform can only succeed if a critical mass of users can join. This is a necessary, but not sufficient, condition for a platform's success. However, there is a limited understanding of the factors that contribute to reaching such critical mass. In this study we identify ways to determine the market potential of a platform and to reach critical mass. We particularly enrich past studies by exploring how the openness of a platform influences market potential. We examine openness at three levels – provider, technology, and user level – and ask the question: to what extent can opening (or closing) each level increase or decrease a platform's market potential? The provider level recognizes the strategic involvement of key stakeholders that provide a platform. The technology level is concerned with the interoperability of a platform across different technologies. The user level relates to what extent a platform discriminates different segments of the customer base. On the basis of analytical modeling and theoretical analysis, we formulate four propositions concerning the effects of openness on platforms’ market potential. We illustrate the strength of propositions through a confirmatory case study, which is informed by five theoretically sampled cases. The cases illustrate cogently the effects of opening different levels of a multi-sided platform. In conclusion, we propose a decision model that can assist decision making concerning the opening of a platform to catalyze its growth.

The Impact

In a global context increasingly concerned with climate change, understanding the impact of economic growth on the environment is becoming crucial, especially for developing countries. Morocco has been committed to the United Nations Framework Convention on Climate Change (UNFCCC) to achieve the objectives set for reducing greenhouse gas (GHG) emissions by 13% by 2030, with 2010 as the reference year. Such a target could reach 32% by the same horizon under certain technical, financial and capacity building support conditions.The main emitters of greenhouse gases (CH4 and CO2) are landfills because during the decomposition of solid waste CO2 is the most present gas pollutant is for this reason focuses this case study carried out in a landfill located in Fez, the development of a new calculation method or we could have a reduction in CO2 41261,69 teq CO2/year and with a yield of 85%.

The paper examines the impact of INGOs on the democratization of developing countries. Following the &lsquo;end of history,&rsquo; the INGOs multiplied globally, and the number of aids to developing countries was given through them in billions of dollars in the past three decades. It is envisaged that with the increase in their population, the developing countries will be better off with a standard form of living that is attributable to standard democratization. However, despite the billions of dollars spent, the citizens of the developing countries are still worse in poverty, poor leadership, and corruption. On the contrary, some countries, including Nigeria, are threatening legislation that will curtail the INGOs, sighting their opacity and lack of tangible results as reasons. The research used Nigeria as a case study to analyze the methods, approaches, and the capacity of these INGOs and how they affect the democratization of their host countries. Through a review of existing records, non-participatory observations, and reviews of conference proceedings. The paper analyzed the parallel gaps that exist by arguing that, taking a broad, multi-disciplinary method from the various works of literature studied will provide essential conceptual and practical insights that can inform current debates.
