Essay On Importance Of Zero

[Evelyn Normington]

Brahmaguptathe Indian mathematician and astronomer, first defined the number zero and its operations and developed a symbol for it.

The ancient Mayans independently developed zero in their number system in Central America.

The requirement of zero in maths is significant as the additive identity of the integers and real numbers. Zero also plays a critical role in algebraic structures. As a digit, zero is important as a placeholder in the place value system.

And not to forget the importance of zero becoming the basis for the binary system of computers.

Everything digital today depends on zero. The computer understands binary language, which consists of two digits: 0 and 1. So the digital age could not have been possible without the ubiquitous zero. Hence proven, that the requirement of zero is felt in our everyday lives.

The project focuses on the investigation of zero waste management as a viable option for saving the planet from pollution and increasing environmental sustainability efforts. The introduction gets the audience acquainted with the general idea of the paper and the key concept investigated. A relevant model supporting the rationale is the 3R approach. The methodology section briefly presents the methods utilized in research and the questions to be answered.

Findings from the literature point out the main points singled out in research articles. The SWOT analysis includes an overview of the major strengths, weaknesses, opportunities, and threats of zero waste management. In the recommendation section, suggestions for promoting zero waste are given. The conclusion reiterates the main points made in the project.

The most relevant model of zero waste management is the so-called 3R model: reduce, reuse, recycle. The model comprises such aspects as development, production, construction, use, and disposal (Singh, Ramakrishna and Gupta, 2017). Zero waste, which incorporates two main aspects, is the major goal of the 3R model. The factors most closely related to zero waste are the recycling of waste and sustainable manufacturing (Singh, Ramakrishna and Gupta, 2017). Recycling may include e-waste (electric and electronic), ceramics, machine scrap, and other types of waste. Meanwhile, sustainable manufacturing involves the most recent trends in the machine industry, foundry, and operation.

The methods to be utilised in research are ethnography and a review of literature. These qualitative approaches allow collecting a sufficient amount of data on the selected topic, sorting it out, and making viable conclusions about the subject of investigation. Ethnographic material will be taken from scholarly articles and reviews. The current study aims at answering the following research questions:

Although the study does not involve any experiments on living beings or data collection from specific participants, it is crucial to adhere to the rules of research ethics. In the case of the present study, the ethical principles to be followed include the authenticity of materials used and paying tribute to the authors whose scholarly works are being consulted. To pursue the first aim, only peer-reviewed articles will be utilised as sources. To follow the second goal, each thought or idea borrowed from the literature will be properly cited.

Many recent research studies are dedicated to the problem of zero waste management and the ways of its implementation. The articles by Pietzsch, Ribeiro, and de Medeiros (2017), Song, Li, and Zeng (2015), and Zaman (2015) focus on zero waste management, its benefits, challenges, and strategies. Pietzsch, Ribeiro, and de Medeiros (2017) note that a consensus on the concept of zero waste has not been gained yet. Still, the scholars have singled out four dimensions of benefits brought by zero waste to society: community, financial-economic, environmental, and industrial.

The main challenges have been found in the micro (stakeholders), meso (municipalities and industries), and macro environment (politics and culture) (Pietzsch, Ribeiro and de Medeiros, 2017). Song, Li, and Zeng (2015) also acknowledge the presence of barriers on the way to zero waste, such as the lack of efforts taken in the spheres of e-waste, packaging, and food waste. Researchers also note the inequality in waste management opportunities in developed and developing countries. Therefore, it is crucial to consider the variability of challenges related to zero waste implementation in each particular state.

Zaman (2015) emphasises the significance of zero waste in the confrontation of waste problems prevailing in the world. The scholar notes that the main reason why zero waste has gained popularity with policymakers is that this concept helps to promote a variety of beneficial processes. Among them, there are the sustainability of production and consumption, considerate recycling, and recovery of resources. Still, while Zaman (2015) mentions that zero waste is a positive idea, the scholar also argues that the design and evaluation of this important concept have not received sufficient attention yet.

Principato, Pratesi, and Secondi (2018) explore the advantages of zero waste introduction in the restaurant sphere, whereas Sharma et al. (2017) discuss the feasibility of zero waste for paper and plastic waste. Scholars note that zero waste management will become possible due to the increased use of sustainable materials, which are characterised by renewability, natural abundance, and easiness of accessibility and recyclability (Arevalo-Gallegos et al., 2017).

Baghbanzadeh et al. (2017) have found that the process of water distillation is more energy-efficient if performed with the use of the zero-waste approach. Meanwhile, Sharma et al. (2017) remark that zero waste goals cannot be gained without total recycling of plastic and paper waste. Hence, scholars acknowledge the significance of the zero-waste policy but note that it is impossible to achieve without altering the current ways of managing waste and using resources.

Finally, several scholarly studies are concentrated on various functions of materials that can be utilised in order to increase zero-waste efforts. Burlakovs et al. (2018) emphasise the need to reduce waste disposal and recover materials and metals as a necessary prerequisite of the successful movement to zero waste. De Bhowmick, Sarmah, and Sen (2019) analyse the opportunities in the biodiesel sphere presented by oleaginous microalgae biodiesel. Researchers note that the current level of biodiesel development and usage is not sufficient to replace unsustainable petroleum and diesel materials.

Based on the review of literature, it is possible to single out several major findings. First of all, the zero-waste management model is a highly valid approach to reducing the amount of waste produced by people all over the world. The benefits of zero waste are numerous, including the reduction of dangerous pollution, the decrease in waste and material disposal, and the increase in reusability of things.

At the same time, it has been found that the movement toward zero waste is not void of some barriers. For instance, there is currently no holistic strategy for zero-waste programs (Zaman, 2015). Additionally, there is a striking difference in opportunities to implement zero-waste strategies between developed and developing countries (Song, Li and Zeng, 2015).

Statistics indicate that more than 90% of waste in low-income countries is dumped or burned, there being no possibility of recycling it (Solid Waste Management, 2019). At the same time, the status of a developed nation does not guarantee that the citizens are conscious of their environmental footprint. For instance, every U.S. citizen generates approximately 808 kilograms of waste annually (Global Waste Index 2019, n.d.). Still, the main problem is not the amount of waste but the solutions that states utilise to manage it.

Zero waste management is a highly viable approach to minimising the amount of waste generated by people. By encouraging citizens to participate in zero-waste initiatives, governments will promote the elimination of waste, which will lead to lower pollution levels. Sustainability of production and consumption, which can be gained through zero waste, is likely to promote a healthier future for the world. Despite current inequalities in access to zero-waste activities, all countries should strive for participate in this important process.

The concept of net-zero carbon emissions has emerged from physical climate science. However, it is operationalized through social, political and economic systems. We identify seven attributes of net zero, which are important to make it a successful framework for climate action. The seven attributes highlight the urgency of emission reductions, which need to be front-loaded, and of coverage of all emission sources, including currently difficult ones. The attributes emphasize the need for social and environmental integrity. This means carbon dioxide removals should be used cautiously and the use of carbon offsets should be regulated effectively. Net zero must be aligned with broader sustainable development objectives, which implies an equitable net-zero transition, socio-ecological sustainability and the pursuit of broad economic opportunities.
