Amahlati Eco-Tech’s Hot Spot for geysers is a plastic geyser glove that can be fitted over any standard geyser element to push hot water from the bottom to the top, providing hot water within 30 minutes. The conduit is made from plastisol paste and can be retrofitted to any geyser.
6,2 million geysers on the grid consume 40% of monthly electricity at an average heating time of 1.5 – 3 hours. Most alternative products are costly to replace and have a long payback time.
The Hot Spot is a geyser sleeve/conduit that can be retrofitted over any standard geyser element to push hot water from the bottom to the top of the geyser using thermosiphon, providing 50 litres of hot water within 30 minutes at 50 degrees Celsius for use by all households and small commercial users.

Boaberry’s aWetbox – a wetland in a box – is a cost-effective, low-maintenance solution to assist municipalities and homeowners to improve water quality. It can also be connected to grey and rainwater harvesting systems as a water re-use and recycling solution.
Clean water supply and water quantity challenges faced in South Africa
aWetbox – a wetland in a box – is a cost-effective, low-maintenance, carbon sequestrating solution to assist municipalities (critical infrastructure needs) and low- to high-income home owners to improve water quality with downstream business opportunities. It is an integrated grey water treatment and rainwater harvesting and treatment system for water optimization, availability, re-use and treatment.

Cocos Solutions’ superhydrophobic HV coatings are intended for use on power networks for anti-pollution (AP) and anti-icing (AI), thereby reducing power outages and saving energy.
Power utilities suffering outages due to pollution and icing on insulators, sub-station bushings and conductors, which result in outages/power failures on ageing electrical grids globally and a loss of energy efficiency.
Coco’s Solutions develops and sells specialised coatings for high-voltage electricity networks. Such coatings have anti-pollution (AP) and anti-icing (AI) properties, and are superhydrophobic and ice-phobic. The coatings have been evaluated and accredited by Eskom and insulator and conductor OEM’s at independent laboratories, and have consistently performed outstandingly well against similar products.

Isidima Design’s Arumloo is a ceramic toilet effectively flushes on less than 2 litres of water, significantly reducing household water demand and provides access to flush toilets where limited water is available.
Water scarcity and the large number of households in South Africa without access to effective sanitation
The Arumloo is a beautiful, innovative toilet capable of flushing on less than two litres of water, significantly reducing household water demand and giving access to flush toilets where there is limited water availability. Inspired by the elegant vortex form of the Arum Lily, the patented design of the Arumloo is the greenest flush toilet on the market and defines a new standard in Water efficiency.

SanAqua HCA’s Hydrochemical Activation Treatment (HAT) system treats water of varying quality and enhances other water treatment systems cheaply and efficiently.
Health, economy and food security is threatened by declining water quality as harmful pharmaceuticals, herbicides, pesticides, organics and pollutants remain after expensive, chemical and skills intensive, conventional treatment.
The HAT System™ is a small, electronic water treatment component. It is modular so is capable of improving treatment of small to large quantities of water ( from 1kl/hr up to very large plants). It uses no chemicals, requires low skills to operate and by disrupting and coagulating harmful pollutants, cleans water more cheaply and effectively than ever before.

Sustainability Professionals’ Mashesha syngas stove cooks with large pots for institutional use. The stove uses biomass/wood fuel, but needs 50% less fuel than what is required for open fires and is also much safer.
Health and environmental hazards of cooking on open fires in makeshift kitchens at schools across South Africa and in other SADC countries
The fuel-efficient Mashesha Syngas Stoves cook with large pots, for institutional use. The stoves use biomass/wood fuel, and the fuel consumption is half of what is normally required with open fires. The stoves are also much safer, since a closed gasification process is utilised for combustion.

Thevia Roof Tiles are made from 99% waste materials (crusher discard and recycled HDPE). The tiles are twice as strong and 75% lighter than normal cement tiles, with a similar manufacturing cost.
Every year South Africans produce 315 million tonnes mining and 1.5 million tonnes is plastic waste. We also produce 120 million concrete roof tiles of which 12 million break in transit and when handling. What if we could use the waste to make stronger tiles?
Thevia manufactures roof tiles made from 99% waste materials (crusher discard and recycled HDPE). Thevia tiles weigh a quarter of a traditional concrete tiles, but are twice as strong and not brittle (<0.1% breakage). When compared to the cheapest competitors’ concrete tile, the price and benefits of Thevia’s tiles provide an 8 –15% cost saving on total roof installation.
