SDG6: Clean water and Sanitation

- Our leather product will be able to complete the sustainable development goal number 6, clean water and sanitation. Our project will rid pollution coming from traditional leather companies because we will not produce either metal pollution, water pollution, or gas pollution into the environment. Our product is fully natural and biodegradable, and would not in any ways harm the environment.

SDG13: Climate Action

- The leather industries have emitted large amounts of gas into the environment, contributing to global warming and climate changes. However, our product will change this issue because we don’t need the involvement of gases, and only require supplies such as tea and sugar. Therefore, we would solve the issues concerning gas pollution from the leather companies, and lead the leather industry to develop positive climate action

SDG15: Life on Land

- To protect the animals that were been exploited for the leather products they can provide out of their skin, we developed this BCM leather that can be produced from microorganisms without the need to harm any animals. The cows that would be slaughtered for their skin would be saved because we provided an alternative to leather products, and we would lead the leather market to raise the overall awareness of leather farms.

The leather industry devoted to making leather from animal skin is causing tremendous damage to the environment. The food, pastureland, water, and fossil fuel required to raise livestock are all the causes to the high pollution and costs to the environment in farming industries, especially those designated to fulfill leather industrial needs. According to PETA, animals on industrial factory farms, especially leather industries, “produce 130 times as much excrement as the entire human population.” On average, there are more than 1.4 billion cows, sheep, or goats, and many other kinds of animals, that were killed each year for Leather, and there are 2.29 million of other animals like buffaloes, pigs, and others, that were also killed for their skin. The 90% of animal produce, including skin trims, hair, wastes, and others that are not valuable to producing leather, were all wasted despite recycling plans. The aim of our project is to replace the unsustainable traditional leather industry, and bring a new era of more efficient, sustainable, and qualitative leather production. Our project would decrease the waste by-products produced to a great extent because we use Bacterial Cellulose Membrane (BCM) produced by microorganisms as leather supplies instead of Animal Leather. This product will not cause any harm to the animal lives on land and takes the simplest and most sustainable form of the production of leather.

However, these issues will be solved by our leather product. The aim of our project is to replace the unsustainable traditional leather industry, and bring a new era of more efficient, sustainable, and qualitative leather production. Under the condition of producing the same amount of leather product, our project would decrease the waste by-products produced to a great extent. In the United States, 70% of the water pollution came from the leather industries, and this data is not only limited to the states. However, in the production process of our leather, the use of water will be minimized.

The consumption of leather requires sustainability, complete elimination of potential toxic chemical exposure, the presence of renewable energy, and all factors that contributed to the welfare of the environment and the individual. Therefore, the resources used have to be reconsidered to make sure the efficient use of natural resources. However, in modern leather industries, the amount of CO2 released is tremendous, reaching a 15,190 Kg of CO2 for every 100 m2.

Evolution of global population and global CO2 emission since 1900

One of the Sustainable Development Goals (SDGs) of the United Nations is Responsible Consumption and Production, and one of our project’s aims is to achieve the same level of requirement and goals. To reduce the toxic impact brought by leather industries, we developed leather that is produced from yeast and E. coli, which are sustainable. In fact, Cow-derived leather has almost three times the negative environmental impact as its synthetic counterparts, which is what we developed. They are not only edible but would have the minimal potential chemical harm to the users of our product. We would be able to reduce the waste product from the production process to 1% compared to the previous wasted used. According to amberoot.com, the animal skin consists 10% of the whole animal’s value, which means that the real production process wastes almost 90% of the animal produce, despite the plans that were given in recycling the animal meat into factory farms. However, we would eliminate the devastation to animals by using the Bacterial Cellulose membrane our team produced. The production efficiency would largely increase as the time required greatly decrease.

Water pollution as a result of the tanning of leather

The goal of the United Nations was not to just promote sustainable production and consumption but to also enforce the overall awareness of leather farms and the consumer market. Our project would make this improvement a lot easier in the leather market.

The impacts of leather are of course not only limited to the chemical waste produce, but also the destruction to animals that had their skin used for industrial and consumer purposes, which is one of the SDGs “Life on Land.” Around the globe, there are 290 million cows that were used as leather products for consumerism, and is predicted to reach 430 million in 2025 if there were no intersection or intervention to revolutionize this issue. However, our project can solve this problem. Not only that in the production process of our project, there would not be the slightest involvement of animal but instead would only be the coculture of Kombucha, or Komagataeibacter, and Saccharomyces cerevisiae, forming Bacterial Cellulose Membrane. The facility of the whole production process would be different but much more sustainable, since it only requires, in the simplified way, the involvement of tea, a container, and sugar. We will be able to produce a sheet the size of a lamb from only 10L of Kombucha, which would largely increase the production line efficiency in the working process.

This SDG was specifically designated to save the flora and fauna lives on land, which includes the protection of forests. However, the global area that has been used for leather production has already reached 1/10 of the worlds’ total surface area, and it is yet increasing. The ecosystems that were pioneer to the area would experience high and irreversible land degradation, and even biodiversity loss due to the deforestation and exploitation of animal resources by humans. The leather industry also hugely contributed to global warming in a negative sense, provided that the meat, dairy, and leather production specifically accounts for around 14.5% of global greenhouse gas emissions. The water pollution is also devastating, and makes up a high percentage of the global water pollution total. However, with the adoption of our project, these problems would be disentangled naturally without significant obstacles. Our project has the minimum costs but produce the greatest benefits, and with the sustainability of our product, it would indeed be revolutionary for the entire market of leather industry.
