Sustainable Leather Alternative

Field of Invention
The present invention is a bio-based, environment conscious material that serves as an alternative to traditional leather. This new material is based on the concepts of circular economy and sustainability, targeting UN Sustainable Development Goals (namely, Climate change, Life on land and Life under water). Main aim behind this work is to develop new, sustainable material utilizing the potential of marine seaweed or algae and organic food waste that fills up the landfills, rots and releases harmful greenhouse gases such as methane, leading to global warming. It also aims to bridge the gap between design, science and sustainability, providing a step towards a sustainable lifestyle.

Background of Invention
Materials play a very crucial role in configuration of things around us, our ecosystem and our lives. Objects that we use on a day-to-day basis, be it indoors or outdoors, nurtures us, providing functionality, comfort, and impacting the ecosystem that we live in. These materials impact how we behave, live, and accommodate in an ever changing, evolving world. They carry particles of form and functionality that fulfil our needs. Not just needs, it becomes a symbol of our cultural and traditional values. Millions of years of evolution led to formation of a robust ecosystem, where one species depends on the existence of the other, utilizing natural resources, co-existing in a beautiful ecosystem. However, domination of one species, ruthless appropriation, abusing the natural, abundant resources and technological advances have led to an unbalance in the ecosystem. Human’s unleashed attitude towards nature has pushed the boundaries of a balanced ecosystem, far beyond the advisable. The resources which were accessible to many species, have now being distributed in an unfair manner, leading to drastic consequences for the climate and environment.
Species extinction, burning of agricultural waste, food waste from landfills leading to air pollution, climate change, ozone layer depletion, plastic pollution in water bodies and land, origination of new kinds of diseases are the issues to name a few, that our world has been witnessing. Boundaries have been pushed so hard that there is an urgent requirement to bring the change in our mindset, lifestyle, approach to building things and materials, utilising the available resources in a sustainable manner so that the positive changes can be seen. And, one way to bring those changes is to go from linear to a circular approach.
The general trend of linear economy has led to more consumption as required, which has led to developing more that required which ultimately led to more waste generation, be it electronic goods, apparel or food (Ghisellini et al., 2016). Linear economy contributes to usage of more resources which results in scarcity of the resources, making them more expensive, degrading products and materials value while polluting our environment. Meanwhile, the circular practices and circular economic models are being proposed to keep products and materials value, minimize waste generation, fight against resource scarcity and reduce our carbon footprint on nature (Foundation, 2013; Ghisellini et al., 2016). Inspired by natural cycles, the circular economy aims to close the loop of industrial material flows by using waste as a source to produce new products and services.
There are a lot of issues related to our current use of materials leading to different kinds of environmental pollution such as plastic pollution, land degradation, air and water pollution etc. Since the arrival of covid-19 pandemic, there has been a significant increase in the use of plastic based products ranging from plastic sanitizer bottles, face shields, gloves, personal protective gears etc. This resulted in a massive disruption of supply chain and waste disposal systems. The material used for PPE involves thermoplastic or other synthetic plastic polymers that are not easily recyclable or compostable. Increase in usage of these non-biodegradable, non-recyclable products lead to accumulation of waste in landfills, water bodies, clogging sewages, passing on from lakes, rivers to the oceans which is impacting aquatic life as well as the quality of water that we consume. There are high risks of marine animals consuming and feeding on such waste which is lethal for their lives. Such plastic polymer-based products are undoubtedly useful during medical emergencies but it is promoting single use plastic material in our economy.
It is estimated that since the outbreak of Covid 19, the amount of plastic waste generated worldwide is approximately 1.6 million tonnes per day. Throughout the pandemic, till now, our world witnessed a rise in demand for plastic products such as masks, bottled water, sanitizers packaged in plastic bottles, disposable gloves, disposable cutlery etc. (Syam, 2020; Nzediegwu and Chang, 2020).
Similarly, there has been an increase in organic waste such as food or agricultural waste since the Covid 19 pandemic started. The activities of industries that maintain, monitor, and recycle organic food waste has been affected due to the pandemic, which lowered down the rate at which food waste used to be processed. Also, due to restrictions on import and export, large amounts of food is going to waste. Organic waste, when accumulated in landfills, starts rotting and leads to releasing harmful gases like methane (extremely flammable) and other greenhouse gases which contribute to climate change. Food wastage has always been a matter of concern in India. Around 40% of food grown in India spoils and goes to waste before reaching consumers. Now, Covid-19 pandemic is adding more to organic waste. The UN has warned that methane levels may rise sharply due to it in the pandemic and even after it.
There has been a lot of awareness regarding the issues of food and agricultural waste and new materials are being made for the circular economy, where waste from food industries and farming are being used as resources for development of new, sustainable materials for the betterment of the society and our ecosystem.
Not just the problems associated with plastic based products, the manufacturing of animal-based leather also leads to severe outcomes, such as major carbon emissions resulting in greenhouse effect, usage of harmful toxic chemicals for tanning that results in degradation of water quality in our water bodies such as rivers & lakes. These toxic chemicals also lead to serious skin diseases and many other health issues for the workers working on the field.
There are numerous ways to make bio-based materials from resources like cassava, corn, milk proteins, gelatin, wheat, collagen etc., it raises a concern over its sustainability with respect to competition between land and water resources for human needs (Wen Yi Chia, et al, 2020). Also, when it comes to bio-based materials made from raw materials and food crops like cassava starch, corn, there are concerns over poor water resistance, strength and other mechanical properties. Moreover, it is difficult to extract polymer from plants and food crops due to the presence of layered cell walls. So, it is very important to use raw materials that overcome the aforementioned issues with respect to sustainability as well as mechanical properties.
There is a dire need to utilize the renewable resources from nature and develop materials for products that can help manage and control the waste (organic as well as synthetic) that can contribute to a circular and sustainable lifestyle. Many brands and designers are working on the same issues. Some of them being, Mycoworks (Patent no. US20120135504A1), that harnesses the potential of mycelium and develops leather alternatives. Similarly, Ecovative designs (Patent no. US20170049059A1, EP2094856B1) uses mycelium-based technology to develop solid biocomposites for packaging purposes as well as leather alternatives. Other than mycelium, some brands utilize plant-based raw materials to develop leather like material. For example, Pinatex (Patent no. US20130149512A1), produces leather alternatives from fibers from pineapples which are sourced from plantations in the Philippines. Another brand by the name Tomtex, develops material from waste coffee grounds and chitin which is found in exoskeletons of crustaceans and sourced from discarded seafood shells. Another brand from India that goes by the name Malai Eco, develops leather like material from bacterial cellulose and waste coconut water in the state of Kerala, which otherwise goes to waste and degrades water and soil quality.
So, from examples of such brands, we can observe that there is a lot of potential that organic waste resources hold, from food or agricultural industries and can be utilised rather than harnessing raw materials such as fossil fuels to do the same.
With respect to the resources required for developing a circular model, it is important that local and renewable resources are put to use. Using local resources defines a path for positive social impacts as well such as reducing local communities’ dependency on imported materials, benefiting local economies and increasing their self-sufficiency. At design phase level, we should boost the creativity that can be generated when people work together to create something for the social and natural environment they live in (Manzini, 2015; Thackara, 2015). When that happens, people tackle the most essential issues for living, such as increasing energy, water or food self-sufficiency. Solutions obtained from these kinds of design processes might not be very high-tech solutions ever but it will contribute to solving real and tangible problems from individuals and communities.

Summary
As a sustainable, environment friendly material, the proposed intervention aims at harnessing the renewable resources from nature such as marine seaweed which is abundant in nature and do not pose threat to land, food and water resources for humans and animal’s needs; which is not the case when it comes to the use of resources like cassava, corn starch, wheat, collagen, gelatin etc. as it is difficult to process biopolymers out of them and causes a competition for land and water resources usage for many other purposes and consumption. Cultivation of seaweed which is used for development of the proposed invention, has a lot of potential with respect to sustainable material development, can be grown on non-arable surfaces and require less time for harvesting. Different species of seaweed are present in abundant amounts in the water bodies such as oceans, lakes which are helpful for potential usage. When compared to the food crops such as corn, wheat, cassava, seaweeds do not compete with food production for human consumption. Also, marine seaweed or algae are a good source of carbon dioxide absorption (which helps in diminishing the greenhouse effect), have high nutritional and antioxidant values, tolerant to harsh environmental conditions and help in wastewater remediation. So, the use of marine seaweed-based biopolymers has a lot of advantages for sustainable material development. Also, this material intervention uses the potential of organic waste such as vegetable and fruit peels, discarded nut shells, wood chips, natural fibers (rich in cellulose, hemicellulose, lignin) that possess high antimicrobial and antioxidant properties. This organic waste otherwise ends up in the landfills, rots and releases harmful greenhouse gases such as methane, contributing to the global warming and climate crisis.
For the purpose of dyeing, plant-based natural dyes have been used which are non-toxic and completely biodegradable. It also leaves behind a very natural scent and soft texture which adds value to the material. The surface of the proposed intervention is waterproof, which is made from using natural waterproofing agents. No chemicals have been used in the entire process.
Targeting Sustainable development goals (Life on land, Life under water and Climate action), all the raw materials used for this proposed material are 100% organic, biodegradable and environment friendly, which results in a leather like material which could potentially be used in industries like apparel, furniture upholstery, accessories, bags, decorative items etc, and once its usage is done, this material can be composted into a composting bin, where it biodegrades, leaving behind no harmful components at all.
What is taken from nature, goes back to nature, forming a sustainable loop.

Process for the preparation of Sustainable Leather Alternative
For the proposed novel invention, natural non-woven multi-layered stacks (11) are made using natural fibers (such as cotton, jute, banana fibers etc), which can be same or different, comprising a composite fiber material of about 20 to 50% w/w and biopolymers from red seaweed or algae (9) are used, from about 1 to 30% w/w. The natural fibers used for the proposed invention have a high cellulose, hemicellulose and lignin contents. Biopolymer used in the process is fusible at high temperatures of 100°C or less.
The Non-woven natural fibers (11) are processed with Marine seaweed/algae extract biopolymer (9) at high temperatures of atleast 100°C. Plasticizer (17) such as Glycerol or Glycerine is used for the purpose of plasticizing the biocomposite, ranging from 1 to 10 % w/w. The Vegetable peels, nutshells, woodchips, Flower, Fruits and other organic waste and its extracts etc (10) such as Vegetable peel extracts like beetroot extracts, nut shells such as walnut shells, discarded wood chips, etc. are used in different quantities for the development of proposed bioleather sheets, ranging from 1 to 25 % w/w. The biopolymer is fusible at high temperatures and undergoes a heat treatment for up to 60 minutes. Biopolymers bind themselves with organic waste extracts when treated at high temperatures of 100°C or less. For the purpose of dyeing or coating the material with pigments, plant based natural dyes (12) are used such as dyes extracted from nutshells, wood chips, flowers of rose, marigold, hibiscus and Indian madder, Indigo, Myrobalan, although not limiting to these. Flower extracts and organic dyes such as Indian madder, Indigo, Myrobalan are heated up to 3 hours and kept overnight in some cases for the development of desired pigments. Quantities of dyes used for the purpose of dyeing the material ranges from 1% to 25% w/w, resulting in natural fragrance and soft texture. Once the heat treatment of biopolymer fused with organic waste extracts and natural fibers composites are done, it is set into moulds for desired sizes and allowed to be completely settled, a few days (3-7) after which the bioleather (3) sheets are procured, depending up on the humidity and temperature levels. For the purpose of developing a waterproof surface, natural waterproofing agents such as beeswax (21) in 0.1 to 5 % w/w is used and a coating is applied on the surface of developed bioleather (3).
After the bioleather sheets are fully developed, stitching and embroidery techniques such as Zardosi are performed to test the strength and its ability for surface manipulation.

The developed bioleather is also subjected for various technical and analytical tests, for the product quality evaluation. The results from the technical tests done for measuring tensile strength, tear strength, thickness, GSM are mentioned in the tables above.
