Energy From Waste

Considering the confrontation of waste disposal and minimizing Green House Gas (GHG) emission, technologies of Waste To Energy (WTE) production seem appealing. It provides one key solution for two major concerns regarding energy crisis and waste management. Energy from biomass can be seen as a promising alternative for fossil fuels, which are getting scarce and more costly day by day. Since a significant amount of organic waste from agriculture, industries, and community sources is collected annually, it can be convertible to useful energy forms like biohydrogen, biogas, bioalcohols, etc., through various Waste-To-Energy Routes (WTERs) for sustainable development. The adoption of this WTE technology will help the world not only in saving the traditional energy resources, but also in reducing GHG emission, and lowering environmental impact. With all these advantages, WTE industry is expected to experience a noticeable growth in the coming years and make greater contribution in supplying renewable energy. The review presents the technical, economical, and environmental aspects of various WTE techniques and focus on the benefit that this thermochemical conversion is a step forward towards sustainable development.

The Impact

Access to energy is crucial in tackling many of the current global development challenges that impact on people’s economic, health and social well-being as well as the ability to meet the commitments of reducing carbon emissions through clean energy use. Despite increased attention from multiple governments and agencies, energy poverty remains a serious sustainable development issue in many developing countries. To date, most research have focused on general access to electricity and the generation of clean energy to replace fossil fuels, failing to address the lack of basic access to clean energy for cooking and heating. More people in the world lack access to clean cooking fuels than to electricity. This issue is one aspect of a broader research which investigates the impacts of optimized energy policy and energy business models on sustainable development in developing countries.

Original Type

In the past architecture of Iran, traditional architects had been able to provide comfort for residents through the smart use of architectural materials and strategies. Soil architecture is the most original type of Iranian architecture and the use of soil with characteristics such as high thermal capacity and thermal latency is at the cutting edge of this field in energy consumption and the pursuit of sustainable architecture in the world. This type of architecture not merely in the form of constructing a building in a single ground, but it has been united proportional to the scale and location of the project on the ground and an indivisible part of it. The research method adopted in this paper is based on text studies and the use of visual documents in the context of library research and descriptive-analytical method. In this research, a comparative study of the principles of sustainability with the vernacular architecture of Iran and the sustainable elements, including Shaw Shawādān, sunken gardens and etc. have been addressed in traditional Iranian architecture. The results of these studies show that desirable solutions derived from this vernacular architecture for achieving sustainable architecture can be presented for reducing fossil fuels and as a result reducing contamination that plays a significant role in these issues and the issue of sustainable development.

Abstract Recognition that hydropower plays a role in fostering sustainable development and helping countries move away from fossil fuels has led to a resurgence of planned projects on transboundary rivers around the world. Whilst these projects offer clear benefits, they are not without their socio-ecological impacts. An added feature of hydropower projects is that they tend to involve a wide range of actors that are responsible for their financing, planning, construction and operation (international and domestic; private and State). This begs the question, if it is ultimately the responsibility of States to ensure that these projects are in accordance with international law obligations, what does that responsibility entail when much of the activity is conducted by private companies? International law has a long tradition of placing States under an obligation to regulate the conduct of non-State activities so as to prevent transboundary harm. However, a closer review of the law relating to transboundary hydropower projects reveals that more could be done to guide States as to the appropriate measures that they might put in place to ensure that any hydropower projects involving private actors are implemented in an equitable and sustainable manner.

The burning of fossil fuels is an unsustainable activity, which is leading to an increase in greenhouse gases (GHGs) emissions and related global warming. Among sustainable energy sources, microalgae represent a promising alternative to fossil fuel and contribute to the achievement of important Sustainable Development Goals (SDGs). In particular, the potential contribution of marine microalgae to sustainable development is large as, among other benefits, they represent a carbon negative energy source and may be applied in many coastal areas around the world. Despite this, significant economic and technological improvements are needed in order to make microalgae biofuels viable on a large scale. This review aims to explore how and to what extent third-generation biofuels (marine microalgae, but also the latest advances in freshwater microalgae) can benefit the realization of these SDGs. From this study we concluded that the production of large-scale marine microalgae biofuels is not yet feasible from the economic perspective at a large scale. However, the cultivation of microalgae in seawater holds great potential for increasing the small to medium viability of this biofuel source. The possibilities for improvement along with the contributions to sustainable development lay the groundwork for continuing to study and apply the potential of sustainable production of microalgae bioenergy.

Ecologically Sustainable Development

Protection of the Environment and Sustainability goes hand in hand as one mechanism compliments the other. On the other hand, Sustainable Economic Growth can only be achieved if it is linked to Ecologically Sustainable Development (ESD). Sustainability can best be described as "Living within the limit of what the environment can provide while safe guarding the environment for future generation, Understanding the many connections between environment, society and economy, and equitable distribution of resources and opportunities". Uncontrolled Green House Gas Emission has caused global warming, sea level rise, change of weather pattern (e.g severe untimely rainfall at unusual location), and alarming increase of natural disasters (Cyclone, Hurricane, Floods, Tsunamis and other natural phenomena). Third world countries are worst affected by the Green House Gas Emission and Global Warming Impact and Bangladesh is one of them. UN has taken a leading role and guiding the world to work together not only to reduce pollution but to make significant contribution in achieving pristine environmental conditions. Under the umbrella of UN, the world is now taking collective action to reduce Green House Gas Emission and Tackle Global Warming Impacts. Concerted efforts must be taken in an accelerated pace to educate at Global, Regional, National and Community level, about the benefits of the above-mentioned concepts and introduce incentive-based programs for mass participation. The environmental cleanup process should start from individual home and gradually extending to community, national and global level to achieve accelerated measurable success. An opportunity must be created to reform land use change, replacing pollution producing industries with environmentally sustainable practices. It is overdue to put through a series of EPA recommended processes to clean up the contaminated land, soil and water and secondly, introduce and adapt an Ecologically Sustainable Development program. The long-term goal should be to expedite and spread the land use change practices to relace the contaminated practices and introduce mandatory adaption of environment friendly technology for the ongoing industrial and business activities to reduce pollution while contributing improving the environment. With a global collective action this world can be transformed into a heaven on earth.

Waste-to-energy (WtE) could prevent the production of up to 50 million tons of CO2 emissions that would otherwise be generated by burning fossil fuels. Yet, support for a large deployment of WtE plants is not universal because there is a widespread concern that energy from waste discourages recycling practices. Moreover, incineration plants generate air pollution and chemical waste residuals and are expensive to build compared to modern landfills that have appropriate procedures for the prevention of leakage of harmful gasses. In the context of the EU, this paper aims to provide a picture of the actual role of WtE as a disposal option for municipal solid waste (MSW), enabling it to be utilized as a source of clean energy, and to address two important aspects of the debate surrounding the use of WtE; namely, (i) the relationship between WtE and recycling, and (ii) the effects of decentralization, waste mobility, and plant ownership. Finally, it reviews the role of the EU as a supranational regulator, which may allow the lower government levels (where consumer preferences are better represented) to take decisions, while taking spillovers into account.

Nuclear option is in a unique position to restore its original role of the main source of energy with an increased attention paid to the security of electricity supply as well as regulatory changes affecting fossil fuels, particularly with due introduction of climate change prevention measures. Recent developments indicate the advantages of nuclear option over other possible options in terms of sustainable development. However, a large number of controversial issues on nuclear energy make its reversal less clear. These are discussed with particular attention paid to recent developments worldwide, including the World Summit on Sustainable Development held in September 2002 in Johannesburg, South Africa.

The linear economic model consumes large amounts of energy and resources, but the limits on its physical capacity are being reached. The circular economy (CE), conversely, is reparative and regenerative; it aims to ensure that products, components, and resources maintain their usefulness and value. Tourism is a generator of wealth and employment worldwide (9.8% of world GDP and 9.1% of world employment), but it also contributes to a variety of environmental problems all over the world. Reducing the negative impacts of the practices of the tourism sector is essential. Therefore, implementing CE practices in this sector is crucial for producing changes that benefit the environment to reach the goal of sustainable development. The objective of this research was to explore the tourism sector knowledge of a CE and the actual implementation of its practices in Puerto Vallarta, and to determine companies´ willingness to design a transition to the CE. Puerto Vallarta, Mexico, is a national tourist destination that ranks among the top three places in the country in terms of the number of tourist visitors, and therefore tourism is the basis of the local economy. A questionnaire was designed to collect information about attitudes and motives, which was answered by key informants from 64 tourism companies. The results show an incipient knowledge about the CE concept. However, companies conducting environmental activities, such as reducing consumption of fossil fuels and improving treatment of waste, indirectly generate a positive impact on the environment. In conclusion, Puerto Vallarta is prepared to implement the CE.

Global warming is increasing due to accumulation of greenhouse gases (GHGs) in the earth’s atmosphere. This is leading to devastating consequences causing floods and droughts in different areas of the globe. The exploitation and burning of fossil fuels on a tremendous scale is the main reason for rising global warming. The approach of sustainable development may help in controlling the rising temperatures. Hydrogen fuel is one such promising alternative clean fuel, that could change the scenario as per the vision of ‘Hydrogen Economy’. A combined approach of switching to cleaner and greener fuel with increased natural sinks for CO2 can provide a better solution to global warming.
