From Snack to Packaging: A Story of Seaweed

Image
 Did you know that fried seaweed is eaten as a snack in some countries of east Asia? As a twist to the crunchy mouth-watering tale, seaweed is also being commonly used as a substitute for plastic . Its biodegradability and ability to form films make it a promising candidate for a biodegradable plastic. Many companies use seaweed as a staple for their plastic-free production such as a previously mentioned Notpla*, but in this article we shall focus on Evoware. To produce this bioplastic, seaweed hydrocolloids are extracted and processed into films. What sets Evoware apart from other seaweed-using companies is that its products are also edible ! (You can reward your act of environmental conscience by a snack of seaweed!)  Seaweed, as explained in our previous article* are easy to produce, as they can grow in both saltwater and seawater and do not require much care, making seaweed bioplastic an even more attractive choice. Even if your seaweed packaging does not end up in your ...

What Water Costs: An Editorial on Water Consumption

Image
 This editorial was posted in The Independent (Tongnip Sunmin) on 30th April 1896 in Korea: Water is of more value than railroads. For instead of saving money it saves lives.  You can estimate the grade of civilizations of any people by the amount of water they use. Paris heads for the list with seven gallons a day for each individual.  It is probable that a quart a day would suffice for the average Korean.

Seven gallons a day! Paris was way up the list. But even back then, some of the Japanese believed in sustainability.  They were willing to recycle water. We've been so involved in trying to stop consuming excess water.  We never thought of the old ways. There is still time to implement old age values into a modern way of livi...

Guilt-free Silk: A Story of Vegan Silk

 Silk is highly desired after for its smooth texture as well as its shine and softness, but a silk cloth comes at the expense of death.* After learning this fact, one may be desperate for a better solution, one for a guilt-free, pain-free silk which still possesses the lovability of silk. If so, we would like to introduce you to a world of plant-based silk. Plant-based silk, as the name suggests, is a vegan form of silk. It can be made from the fibres of plants such as lotus silk, pineapple silk and banana silk. The process of producing this silk, apart from being humane, uses up the unused part of a plant after its use. Lotus silk makes use of the stem of a lotus plant, which are left behind after the blossoms are plucked off. The fibres from the lotus stem are processed and woven to be turned into silk. Banana silk too makes use of an unused plant part- the peel. The fibres of the peel are woven into banana silk. Pineapple silk is made from the unused leaf of a pineapple plant, w...
