Recycling: From diving wetsuit to laptop bag

When Dipesh Pabari of Camps International sent me pictures of these laptop bags and bottle can holders, I just knew it would be something you AfriGadget fans would appreciate.

Recycling wetsuits

The fact that discarded waste is converted to something very useful… Its definitely AfriGadget. I asked Sander Den Haring a few questions about these cool products.

Recycling wetsuits

How did you begin your company?

I was born in a small town called Hellevoetsluis in the Netherlands but only lived there till i was 5. At that point my family moved to Yanbu, Saudi Arabia where i grew up and ended up spending 16 years. Yanbu is an industrial town situated on the Red Sea and i believe that a lot of the what, who, why and where i am is as a result of this. From the very beginning of our time in Yanbu my parents began a weekly outing to the beach which my brother and i eagerly anticipated every Friday (weekend is Thursday and Friday in Saudi Arabia). Once at the beach we would go out and snorkel virgin reefs in the Red Sea and be stunned by the serenity and tranquility each and every time. My love for the aquatic realm and the conservation of said realm has derived from these expeditions. It led me to complete a Masters in Marine Biology from the University of Groningen in the Netherlands in 2000 so that i could work in the field of marine conservation.

In 2004 i moved to Kenya where i have lived ever since. I began work for Buccaneer Diving as a base manager and soon added on the role of resident marine biologist. Under this capacity i was able to instigate a snorkeling program for some of the underprivileged local government schools in Mombasa (Schools to the Sea program) and an artificial reef program in the Mombasa Marine Park. Both these projects had local partners involved as well. I eventually finished full time work with Buccaneer Diving in June 2009 as the Operations Manager of Buccaneer Diving Kenya and currently fulfill only a part-time quality control position within all of Buccaneer Diving (Kenya and Zanzibar).

I really enjoy thinking of ways to create environmental attitudes and the recycled wetsuit product line has been great in achieving this thus far! We are still coming up with new products and refining the existing products. There are no limits barring our creativity.

What was the inspiration for re-using the diving wetsuits?

In the dive industry wetsuits have a finite lifetime after which they become ineffective (have lost their insulating capability), or they become too hole-ridden to use in a professional business. In the past, these wetsuits were discarded. This seemed an obvious waste of material (as for the sake of a few holes, large patches of usable neoprene were being thrown out), so Buccaneer Diving began looking at what could these patches of neoprene be used for. Traditionally we have used smaller bits of neoprene for various “odd jobs” (eg. snorkel holders, buffering/padding material, informal packaging, patch material for other wetsuits), but these “odd jobs” required small amounts that did not need frequent replacement. So we started thinking if there was anything else that could be made and the obvious item was laptop bags. The bottle/can holders soon followed suit as the sleeves and legs of wetsuits already had the obvious shape (they just needed a bottom added). We are currently making the products more of an “item” and also looking into how we can incorporate the production of these products to benefit other charities. these exciting developments will be happening within the next few weeks we hope so definitely watch this space (it’ll be worth it!).

When did you start selling the bags/bottle covers etc?

This is a new venture and its been active for the last seven months, so still very young. We are looking at various other items we can make from the recycled neoprene (placemats and coasters might be possibilities).

How much do the items cost?

Currently the laptop bags sell for Ksh 2500 (about 32 usd) and the bottle/can holders ksh 350 (about 5 usd)

Are they made in Kenya/Mombasa?

They are indeed produced in Mombasa. Again, the story behind the production will unfold in the next few weeks and its worth the wait.

Where can people order? Can they pay by MPESA (Mobile Money)? (Just kidding, but hey!)

These products can be purchased at the Buccaneer Diving base at the Voyager Beach resort, Mombasa. We have not yet explored the use of MPESA in the purchase of these products as they are still young, but who knows what the future will bring. We can also arrange for products to be sent via courier if people are unable to visit the Buccaneer Diving base. Sander can be reached via email sander at green-water [dot] org.

Flat parabolic mirror is not an oxymoron!

Can a parabolic mirror be flat? Dominic Wanjihias latest invention may prove that this is the most efficient way of capturing solar energy.

Everyone knows what a parabolic reflector is, right? It’s supposed to be a curved surface that collects energy by converging it towards a focus. Parabolic reflectors were invented a very long time ago and have been used in satellite dishes, spot lights and car headlights to name a few. They are also widely used for alternative energy projects to concentrate solar energy for heating and cooking.

Dominic (designer of the flexible solar vest, the solar dryer, and camel milk cooler for Somalia) thinks that the parabolic mirror should lose it’s shape which is an obstacle, to transportation and function.

So how does the flat parabolic mirror work? Dominic has cut inch wide 2 foot long pieces of flexible acrylic mirrors and arranged them at specifically computed angles. When angled towards the sun, this creates a perfectly focused beam of light.

This concentrated energy can be used to heat water in a pipe for numerous purposes including generating electricity. The beauty of this gadget is that

  1. It is very cheap,
  2. It can be quickly dismantled or moved,
  3. It is easily transportable as it can be carried flat or in a tube,
  4. It is easily repaired if broken as the individual mirror pieces can be replaced (rather than having to fix or replace an entire parabolic mirror).

Please note that this is part of Dominic Wanjihia’s ongoing project with Nairobi University and MIT’s FabLab where he is doing a course.

AfriGadget pictures from around Accra, Ghana

I’ve been having a great time in Accra, but not nearly enough time to spend on the details of every cool product or invention that I see. In the meantime, here are a couple pictures from around Ghana that will whet your appetite for what is coming up in the next week:

Distilling water from volcanic steam vents

A unique water harvesting method has been devised in the drought ridden crater of Mt. Suswa, which is dotted with continuously puffing scorching steam vents.

Tapping steam for condensation
Tapping steam for condensation

Taking advantage of the steam vents that dot this landscape, local Masai have ingeniously tapped the vents for steam that is condensed on long plastic pipes that drip continuously into drums. The local Masai claim that these vents can fill half a drum (approx 30 lt) per hour (though it seemed very unlikely to us). The water is sweet and apparently it feeds a community of several hundred people and their cattle with fresh and clean water.

We saw at tens of these contraptions in a particular zone within the outer crater of Mt Suswa. All were protected from animals by thorn bushes. There seemed to be an ownership structure amongst the users, some were better constructed, had longer pipes, were better protected and maintained. We were told that the systems were installed fifteen years earlier and it did not look like any modifications had been done since then.

The water distilling system used here is permanent and produces a continuous supply of clean water that is collected regularly by the local community. The system we observed was in the area called Kishalu – just beyond a school. The system could be more efficient at trapping condensation – much steam was wasted as pipes were quite short, and collection drums were left uncovered and open to evaporation. The beauty of the system is that it works overnight. These water distilleries were introduced to enable the community to survive the dry season when rain water catchments had dried up.

The Suswa system is infinitely better than the water distilling process on the edge of Lake Elamentaita. Here the local Masai Women daily place a piece of zinc sheeting over a steam vent to capture condensation. They produce only 2 liters per day; a days work to produce enough drinking water for a small family for one day.

If there’s an Afrigadget award out there, the Suswa water distilleries deserve it.
