Cups made from plant know as Risosa Riekerandi. Cups know as Ebisanda(Calabash).

This cups used by our grandparents to drink traditional beer,porridge and milk,fruit bottles used to store liquids.

Idea Title

Idea Summary

Ebisanda (Calabash) made from this plant can address the issue of plastics waste which has affected our planet, and they are natural material without any added substance.

Please include a visual (can be either 2D or 3D) representation/prototype of your concept. (required)

Risosa Riekerandi is plant  grown in all types of soil and in the tropical climate. The plant is useful to make drinking cups known as Ebisanda (Calabash), but now days the plant has died from the environment and most people doesn't value the use of the plant and it's uses. Our organisation has started to revive the plant by collecting seeds and give to farmers groups, we started early this year and the cups from the plant will replace the use of plastic coffee cups which causes environmental pollution to the planet. it is easy to grow and it's first growing plant,and it can be planted with other plants. The plant has a lot of benefits to people such as making Ebisanda (Calabash) bottles we call Ekerandi for storage of milk and they are used for the celebration ceremony of Hellos. We have started to collect seeds and give farmer groups, Youth groups to plant and we are going to form Co.Operative society that can manage all the process, from seed collection to marketing of Ebisanda (Calabash) and straws. Our organisation is inspired to create alternative that can address  problems that affect the planet that caused by plastics waste. 

This solution addresses which of the following:

  • Hot / Cold Fiber Cup
  • Straws

How is your concept recoverable?

The production of Ebisanda (Calabash) it's 100% biodegradable and the plant Risosa Riekerandi covers soil and prevents soil erosion, the leaves can make biodegradable straws. Ebisanda (Calabash), leaves and roots are medicinal.

How have you incorporated additional sustainability attributes (beyond recoverability) into your solution?

All the material from this plant are biodegradable since they are naturally grown. The Ebisanda (Calabash) when dropped into the environment they decompose into manual, making soil more fertile.

What regions do you plan to address with your solution (and how will you accomplish this)?

The solution is intended to be used in the region and globally since the products produced through agricultural farming is that the material can be sourced from anywhere.

Describe your target market. Who will benefit from your product?

We are targeting local families and everyday coffee, porridge drinkers who prefer to use Ebisanda (Calabash) instead of cups /mugs for reusable and disposable products.

What is the current stage of development of your idea?

  • Research & Early Testing
  • Prototyping
  • Piloting

What are the biggest challenges you are facing today? What are existing gaps in your solution?

We are facing financial challenges to support our services as the biggest challenge been having seed Bank, so that we can be scaling the solution in mass.

Samuel Mongoni. Founder and ceo Mr Samuel Mongoni is the ceo of Thetramed Foundation for the past six years of leadership, He has been with passion of leading the organisation to address waste plastic problem in the region ,and member of openideo.

In what city are you located?


In what country are you located?


What is your legal / organizational structure? (if applicable)

Non profit making organisation, Registered with Kenya NGOs coordination board.

Please describe how becoming a Top Idea will support the growth of your concept.

The growth and planting of Risosa Riekerandi with the Ebisanda (Calabash) cup concept will greatly benefit from becoming top idea, as the concept needs much assistance to be adopted on a large scale farming. The funding provide will first go to seed collection and planting. Next the funding would help in product to become more cost effective.

An ordinary cardboard cup breaks down in the natural environment roughly in a year or thereabout. Approximately how the fallen leaves does, consisting of the same cellulose. In order for the new material for the production of cups to become a cost effective replacement of cardboard, it should decompose order faster, somewhere in a month, maybe two or three. This is at an average temperature of 15 degrees Celsius (according to NASA). But when we pour water near a boiling point, at a temperature of 95 degrees, into such cup , according to the rule of Svante August Arrhenius, all the chemical processes in it, including the self-decay of complex molecules, respectively, accelerate. The minimum acceleration will be somewhere 250 times, and the maximum will be about 65,000 times. That is, for a disposable cup that has been filled for at least an hour, and this is a real situation somewhere on a picnic, there is all the chances to pour out their content on the table at best , at worst, on himself or his electronic devices. Even if this cup was made a few days before that and was stored in a stock in perfect conditions.
Therefore, the question arises - how do you deal with such issue?

Thank you Koldun Victor for your comment on our idea on Ebisanda (Calabash) cups, this type of cups made from Risosa Riekerandi (guard plant) fruits are fast decomposable when dropped into the environment also they are free from any chemical on production process. About pouring out the content on the table during boiling point this is hard cause the cups are made when the fruits are ripe and tried probably to sustain breaking on hot substance.
