The generation of solid waste around the world creates problems if not properly managed. The method of processing solid waste by burning or landfill is currently not optimal. The availability of land where the final processing (TPA) is critical, looking for a new TPA alternative will be difficult and expensive, especially in big cities. The processing of solid waste using bio drying technology has the potential to produce renewable energy and prevention of climate change. Solid waste processing products can serve as Refuse Derived Fuel (RDF), reduce water content of solid waste, meningkatkan kualitas lindi and increase the amount of recycled solid waste that is not completely separated from home. Biodrying technology is capable of enhancing the partial disintegration and hydrolysis of macromolecule organic compounds (such as C-Organic, cellulose, hemicellulose, lignin, total nitrogen). The application of biodrying has the potential to reduce greenhouse gas emissions such as carbon dioxide (CO2), methane (CH4), and dinitrooksida (N2O). These gases cause global warming.

History Of

‘What are renewables?’ defines renewable energy and provides a brief history of its use. It focuses on energy generated by solar, wind, and hydropower. These energy sources are renewable, in the sense that they are naturally replenished within days to decades. Only a few years ago, giving up our reliance on fossil fuels to tackle global warming would have been very difficult, as they are so enmeshed in our society and any alternative was very expensive. Nearly all of the sources of energy up to the 18th century were from renewables, after which time the world increasingly used fossil fuels. They powered the industrial revolution around the globe, and now provide most of our energy. But this dependence is unsustainable, because their use causes global warming, climate change, and pollution. Other than hydropower, which grew steadily during the 20th century and now provides almost a sixth of the world’s electricity demand, renewable energy was a neglected resource for power production for most of this period, being economically uncompetitive. But now, renewables are competitive, particularly through the support of feed-in tariffs and mass production, and governments are starting to pay more attention to clean energy, as the threat of climate change draws closer. Moving away from fossil fuels to renewables to supply both heat and electricity sustainably has become essential.

The landfill is a final disposal technique to confine municipal solid waste (MSW), where organic matter is degraded generating leachate and biogas composed of methane gases (CH4), carbon dioxide (CO2) and other gases that contribute to global warming. The objective of the current research was to estimate the amount of biogas generated through the LandGEM 3.03 mathematical model to determine the amount of electrical energy generated and the number of homes that would be supplied with electrical energy from 2021 to 2144. As a result of the application, it was estimated that in the Pichacay landfill, the highest point of biogas generation in 2053 would be 76,982,177 (m3/year) that would generate 81,226,339.36 (kWh/year), and would supply 5083 homes with electricity. Similarly, in the Las Iguanas landfill, the highest point would be 693,975,228 (m3/year) of biogas that produces 73,223,5296.7 (kWh/year) and would supply electricity to 45,825 homes. Of the performed gas analyses in the Pichacay landfill in 2020, an average of 51.49% CH4, 40.35% CO2, 1.75% O2 and 17.8% H2S was presented, while in the Las Iguanas landfill, for 2020 and 2021, we obtained an average of 51.88/CH4, 36.62% CO2, 1.01% O2 and 187.58 ppm H2S. Finally, the biogas generated by being harnessed minimizes the impacts related to global warming and climate change and would contribute electricity to the nearby communities.

On December 1, 2010, a spokesperson for Rep. John Boehner, the leader of the incoming House Republican majority, declared that the Republicans will dissolve the House Select Committee on Global Warming, established in 2007 to provide a forum for discussion of climate change issues. Boehner, like most of the Republican leadership, has long denied the urgency of climate change. In April 2009, as a guest on ABC's “This Week with George Stephanopoulos,” he notoriously compared carbon dioxide emissions to cow flatulence, asserting: “George, the idea that carbon dioxide is a carcinogen that is harmful to our environment is almost comical. Every time we exhale, we exhale carbon dioxide. Every cow in the world, you know, when they do what they do, you've got more carbon dioxide.”

The study aims to focuses on waste-to-energy and especially its current status and benefits, with regard to GHG, renewable energy production and slurry management based on an experience in Nepal. An environment pollution and climate change happened due to green house gases (GHG) emission. As we know that the most of the anthropogenic emission of GHG results from the combustion of fossil fuels but we should also know that environmental concerns such as waste management also contribute for Global Warming. The solid waste management is based on an understanding of MSWs composition and physiochemical characteristics. The results show that organic matter represents 69% of waste, followed by paper-cardboard 7%, plastic 8%, miscellaneous 13%, metal 1% and glass 2%. The major source of GHG from landfill sites which produce significant methane and carbon dioxide gas. The main impact of the methane is on global scale, as a greenhouse gas. Although levels of methane in the environment are relatively low, its high “global warming potential” (21 times that of carbon dioxide) rank it amongst the worst of green house gases. The main cause to increase atmospheric temperature due to highly production of GHG (CH4, CO2 & N2O etc). GHG mitigation measure in the waste include source reduction through waste prevention, recycling, composting, waste to energy incineration and methane capture from landfills and waste water. Specific mitigation option include use of 3R principle; waste segregation, reduction at source; composting anaerobic digestion for biogas; sanitary landfill sites with methane capture; healthcare waste management; proper statutory framework; public participation; private sector partnership; tax waiver for recycling enterprises; and financial management. Regulation is required to ban of recyclable waste in landfill.

Plastic Products

With the ever-increasing population, there is exploitation of our environment to meet the growing needs of the inhabitants. Along with pollution, climate change, global warming, etc., one of the major problems associated with overpopulation is the generation of a large amount of non-biodegradable solid wastes along with various other industrial effluents. Plastic, being inexpensive and durable, have found their way to be produced in large amounts for almost every purpose. This results in the accumulation of plastic products around the world causing plastic pollution. During the past few centuries, the idea of “green chemistry” has gained maximum attention, and therefore, efforts have been made by the researchers to reduce pollution with the help of some environmentally friendly solution. In this concern, bioplastics and biofilms have gained remarkable attention over the last two decades. The major advantages of bioplastics are their biodegradability and the reduced emission of carbon dioxide in their synthesis.

Adaptation strategies to the climate change include measures that can be taken to take account of the new climatic conditions. This paper aims at assessing the effects of climate change on environmental sustainability. This sustainability constitutes a major problem in many countries and regions around the world that experience industrial pollution, degradation of land as well as natural disasters caused by the global warming. The paper shows that adaptation strategies are often parallel strategies that can be integrated simultaneously with the management of natural resources. They can make resources more efficient and resilient to climate change. The paper shows that reducing the carbon footprint by more than 50 percent by 2030 and eliminating it by 2050 might be a viable solution how to tackle the climate change and support the environmental sustainability.

Article endeavors to analyze the prophetic guiding principles regarding human behaviors related to plants and trees being an important component of our environment. The discussion mainly deals with the key environmental issues emphasizing plantation and its significance for balancing the equilibrium of the environment. Additionally, it thrashes out that humans are urged to seedling the plantation even the world is to be ended in Islam. The present study is delimited to the present ecological crises faced by society and a great challenge to the globe. The current ecological problems i.e global warming and climate change are interpreted just to analyze the environmental behaviors in Hadith literature. However, a profundity descriptive study has been conducted in the most influential way to examine the prophetic rules for human behaviors related to trees and plants being environment friendly. Furthermore, the existing practices of humans related to such an environmental sphere also been aptly figure out to highlight all possible ways in the light of prophetic guidance to deal with prevailing environmental issues. Inconsistency between religious teachings and human behaviors need the keen interest of religious scholars and social scientists to carefully harmonize both for maintaining the ecological balance in nature.

My own interest in the topics of this book dates back a good many years. In fact, it predates the emergence of the modern field of climate history, or the identification of global warming as an incipient menace. In saying that, I am claiming no status as a prodigy, still less a prophet. Rather, in my teenage years, I read a great deal of speculative fiction, science fiction, in which themes of climate change and cataclysm have long percolated, at least since the latter years of the nineteenth century. We can debate how accurate the scientific analyses or predictions were in many of these works—in many cases, the level of accurate knowledge was minimal—but those works had the inordinate advantage of thinking through the human and cultural consequences of catastrophe, commonly speculating about religious dimensions. Obviously, some works succeeded better than others in that regard, but the essential project was critically important. If we are foretelling that the world will be assailed by lethal menaces, then we cannot fail to go on to imagine what the political or cultural consequences would or should be....

Structural Determinant

The chapter opens with a discussion of two early instances of global warming cli-fi, Arthur Herzog’s Heat and George Turner’s The Sea and Summer, and argues that both are more or less oblivious to the wider world beyond their respective national frontiers. It proceeds to elaborate an account of the place of SF in the world literary system, understood in Wallerstein and Moretti’s terms as comprising a core, semi-periphery and periphery. This model is then applied more specifically to cli-fi, distinguishing between structural and conjunctural determinants of the evolution of the sub-genre. The main structural determinant, it argues, will be the world SF system. But this may be either countered or reinforced by one or more of three main conjunctural factors: the degree of perceived vulnerability to extreme climate change of any particular national political economy; the salience of Green politics within any particular national polity; and the salience of climate change within broader environmentalist discussions in any particular national culture. The chapter concludes with critical accounts of Kim Stanley Robinson’s Science in the Capital trilogy, Frank Schätzing’s Der Schwarm, Margaret Atwood’s MaddAddam trilogy and Antti Tuomainen’s Parantaja.
