By: Ananya Sharma

Did you know that a staggering one-third of all the food produced globally is thrown away? Among all food groups, fruits and vegetables account for the greatest loss and waste, totalling 31.5% of production. In Australia alone, 7.3 million tonnes of food waste was generated in 2016-17, enough to fill over 13,000 Olympic-sized swimming pools. This wastage comes at a significant economic and social cost, but it also has severe environmental consequences. When food waste decomposes in landfills, it releases greenhouse gases like carbon dioxide and methane. In fact, a single report estimated that solid waste in 2014 alone produced 9 million tonnes of methane in CO2 equivalents. A significant portion of these emissions comes directly from food waste rotting in landfills .

Food waste can be transformed into valuable resources, contributing to a more sustainable and circular economy. One such example is the utilization of waste food as a textile. By processing food scraps, such as fruit peels and vegetable fibers, innovative technologies enable the production of natural and biodegradable textiles. These textiles can be used in various applications, including clothing, upholstery, and accessories, reducing the reliance on resource-intensive and environmentally harmful materials.

Moreover, food waste can be utilized to produce nutrient-rich fertilizers through composting and anaerobic digestion processes. This allows for the recycling of organic matter back into the soil, enhancing its fertility and reducing the need for synthetic fertilizers. Additionally, some food waste can be used as a fuel source through bioenergy production, generating heat and electricity while diverting waste from landfills. These creative approaches not only address the issue of food waste but also contribute to a more sustainable and resource-efficient future .

In recent years, a remarkable trend has emerged at the forefront of fashion: the utilization of unconventional materials such as orange peel, lotus stems, betel nut husks, rose petals, sugarcane, pineapples, coffee grounds, eucalyptus, and even fish scales. What was once considered mere food or waste has now transformed into a revolutionary solution in the fight against climate change. These innovative textile fibers derived from fruit and other food crops have garnered widespread acclaim, earning recognition for their dual benefits: offering a more eco-friendly alternative to traditional textiles while simultaneously addressing the pressing issue of food waste. Moreover, these novel materials have proven to be exceptional substitutes for animal-based products, making them an ideal choice for individuals adhering to vegan lifestyles. By seamlessly blending sustainability, resourcefulness, and compassion, these groundbreaking developments have truly revolutionized the fashion industry.

Circular Systems, an innovative company, has taken on the task of tackling crop residue from hemp, flax, pineapple, sugar cane, and mango farming and transforming it into valuable fibers. With these five crops alone contributing to a staggering 250,000 tons of wasted fiber annually, more than double the demand, Circular Systems has devised an ingenious solution. Meanwhile, Fruit leather Rotterdam has been continuously pushing the boundaries by creating various materials from food waste, including their recent accomplishment of crafting mango waste into unique products. In another remarkable development, students at the University of Delaware have designed a prototype sandal using mycelium, the root system of mushrooms, which naturally binds biodegradable materials together as it grows. Although the mushroom shoe’s sole is yet to be made water-resistant and the flexibility needs improvement, we eagerly await the day when these environmentally friendly footwear options become available for purchase. Furthermore, the ingenious use of citrus waste from the juice industry has given birth to Orange Fiber, a material that has garnered attention from luxury brands since its launch in 2017. Similarly, Pinatex, a leather alternative derived from pineapple leaves, has gained popularity among vegan and footwear brands due to the sustainability of pineapple farming and the additional income it provides for farmers. Last but not least, Vegea, an Italian-based company, has developed a remarkable leather-like material using by-products from the wine industry, such as skin, seeds, and stems. This ground-breaking initiative has earned Vegea well-deserved recognition and acclaim. These remarkable advancements in sustainable materials demonstrate the power of innovation and the possibilities that lie ahead for a more environmentally conscious future.

The utilization of sugarcane fibre, specifically derived from the bagasse of cane stalks, has revolutionized the garment industry by transforming a previously discarded waste product into a valuable textile resource. Known as lyocell, this sugarcane fibre exhibits remarkable characteristics that make it highly suitable for various applications in the medical field. Its exceptional strength, softness, and biodegradability render it an ideal raw material for the production of disposable medical and commercial textiles. Furthermore, the combination of sugarcane fibres with selvage denim, using traditional Japanese techniques, has led to the creation of denim pants and jackets that not only embody a rich cultural heritage but also reflect sustainable manufacturing practices. The year 2017 witnessed a notable instance of fashion’s embrace of sustainability when Livia Firth, the founder and creative director of Eco-Age, made a striking appearance at the prestigious Met Gala. Adorned in a bespoke gown crafted from Piñatex®, a plant-based alternative to leather, Firth’s ensemble sparked meaningful conversations surrounding environmentally conscious fashion choices. The growing demand for textiles made from food and agro-waste, such as banana, aloe vera, and areca nuts, further exemplifies the increasing recognition of eco-friendly materials. Companies like Anandi Enterprises in Tiruppur, Tamil Nadu, have experienced a significant sixfold surge in interest for their sustainable textile offerings, emphasizing the positive impact of eco-friendliness on brand equity.

Sour milk, often considered a wasted resource, possesses tremendous potential to be transformed into valuable yarn and clothing. Since it is unsuitable for human consumption, millions of metric tons are discarded each year. However, by harnessing the protein casein present in milk, a remarkably soft fabric can be produced. The process begins by subjecting skimmed milk to an acid treatment, causing coagulation at a temperature of 45°C and maintaining an acidic pH of approximately 4. The resulting coagulated casein is thoroughly washed, dried, and finely ground into a powder. To dissolve the casein, it is mixed with a caustic soda solution and allowed to mature until it attains an optimal viscosity. This solution is then filtered and deaerated to remove any impurities. Next, the spinning solution is extruded through spinnerets into a coagulating bath, consisting of a mixture of sulphuric acid, formaldehyde, glucose, and water. The jets of the solution coagulate, forming delicate filaments. After passing through the coagulating bath, the filaments are collected together into bunches, known as a tow. To enhance its durability and minimize the impact of water, the tow undergoes a hardening treatment utilizing formaldehyde. Subsequently, the filaments are carefully drawn, washed, and dried, followed by mechanical crimping and cutting into staple fibres. This comprehensive process ensures the transformation of sour milk into a high-quality textile, showcasing the untapped potential of this overlooked resource.

Aquatic salmon leather presents a remarkable breakthrough in sustainable materials, harnessing the power of vegetable-based tanning methods that eschew harmful chemicals.
