Bananas About Bananas

Bananas are the 4th most important crop after rice, wheat and corn. 135 countries grow bananas producing 145 million tonnes per year. The banana industry is worth 52 billion dollars and 400 million people rely on the crop as a staple food or stable source of income. These high figures of production and the aim of producing bananas as cheap as possible for high profits means poor working conditions for workers and a lot of waste. There is a great potential in banana waste i.e. the pseudo-trunk, to be used as an extra source of income by making textiles or using it as a building material.

The Pseudo-trunk

Geometrical analysis of the pseudo-trunk

Otherwise known as the pseudo-stem or ‘false trunk’, the trunk of the banana tree is in fact made out of tightly packed leaves. The cells shown in the cross section transport all the nutrients and water from the earth to the rest of the plant. At the moment, the pseudo-trunk is waste product to the banana industry. It is a heavily un-utilised resource that can be used to make textiles or bio-fuel.

Banana Rope (Manila Rope)

Banana rope has been used historically for things such as ship lines, towing, climbing and landscaping. Manila rope gets its name from the capital of the Philippines, Manila, as a lot of the rope is made there.

The rope is flexible yet non-stretching, durable and resistance to salt water damage. For these reasons its a common choice for ship lines, fishing nets and decorative purposes. It’s used in gyms due to its ability to absorb sweat and therefore act as a good grip.
