Green Finalists for 2016
Nubrix recycles waste paper to create quality affordable bricks to be used for building. The bricks are three times cheaper than conventional bricks and just as strong as conventional bricks. Nubrix aims to be the premier supplier of paper bricks.
A solar powered membrane purification system that uses off-waste material such as macadamia nut shells to purify water at source. The aim is to increase access to water across South Africa.
Roof tiles made from 99% waste materials. A tile weighs a quarter of a traditional concrete tile, but is twice as strong and not brittle (<0.1% breakage). Thevia’s benefits and pricing yields an 8–15% saving on the total roof installation cost.
Share Water System
Share Water System is an innovative water measuring system. It uses low power consumption and enables household owners to limit their daily water usage. This will tackle water restriction facing the country. An amount of water will be allowed to go into a household depending on the family size. The SWS will promote water sharing and responsible usage.
A LED lamp powered by a salt water battery, using novel materials to improve efficiency and operation. Has applications for off-grid lighting and small-scale power supply in under served areas.
Green Finalists for 2015
briGado is a sustainable, manually operated brick making kit, designed to address the issues of housing and unemployment. It equips users in rural and informal settings with the opportunity to make bricks and build their dream homes, and also creates a platform for entrepreneurship, where individuals can use brick-making as a source of income.
OSP cement technology
Small-scale water purification with CSP
NH1-MSsp water security system
myWATT has developed a simple, vendor-neutral energy auditing software that enables electricians and end-users to make informed decisions on energy efficiency interventions, at much lower cost than traditional audits. The application has an intuitive interface and workflow which supports systematic collection of data and recommended solutions.
Waste plastics to fuel pilot plant
Biogas green energy plant
PQRS training and information platform
PQRS is a brand agnostic training, marketing and information portal for solar PV technology; targeting the South African market, locally available brands, installers, suppliers and installations of solar PV systems. Stakeholders can market their services and products as well as training potential clients in the respective technology through the platform.
Ultrasonic biodiesel processing
Vegetable, fruit and garden waste is recycled through a process called vermicomposting to produce a liquid organic fertiliser. This is achieved by feeding the waste to red wriggler worms which are kept in worm factories. The worms eat the waste during decomposition, and give off their leachate (urine). The leachate is harvested and sold to farmers for use as fertilizer.
e’Lite Build – structurally insulated panel
The e’lite™ Build structurally insulated panel (SIP) building system improves on the benefits of traditional SIP structures. It uses recycled honeycomb paper core, expanded and dried in the shape of a natural honeycomb encased in a timber frame and laminated on either side with composite sheets of wood-based and fire-proof sheeting. It improves on the existing SIP system in that the core insulation is not petroleum-based and the outer protective layers are composite thereby providing the necessary protective properties such as fire, water and intrusion protection, and requiring no additional protective layers / work.
SWAG – Solar, Wind, AC and Generator
Multiple renewable and grid-based energy sources are connected to an intelligent controller that learns a user’s power consumption over time, and manages the introduction of the different energy sources depending on current and predicted demand. In addition, excess power can be fed back to the grid.
Green Tower- hybrid solar PV and heat pump solution
The patented Green Tower combines efficient water heating using a hybrid solar heat pump with optional hot water storage, rain/borehole water storage, gray water recycling and solar PV electricity generation. Using a modular and affordable design with factory pre-assembly of key components into an ergonomic frame, installation and commissioning is simplified. The main advantage of a Green Tower is standard installation with little impact on the roof structure while accommodating optional hot water storage and solar PV system.
Heat Pump Dryer
A heat pump technology has been developed for the drying of various South African fruits. The innovation enables fine control over the drying temperature, relative humidity and air velocity enabling better management of product quality than existing methods. In addition, experimental tests have demonstrated a 70% saving in electricity.
SolarPlus Energy Intelligent Controller
Solar Plus delivers solar heating to households with no upfront cost, instead charging a fixed monthly fee for energy. This is managed through a proprietary integrated controller and management platform; enabling real-time energy demand management, remote management, troubleshooting and consumption reporting via the web. The capital cost for renewable energy is eliminated and homeowners move off their reliance on the grid.
The Lightie is an extremely efficient, patent-pending, test-tube shaped solar powered “light bulb”. It is a picosolar device, designed to bring affordable lighting to poor households that still use paraffin for their lighting needs. The Lightie’s innovative design has been crafted to screw on & fit flush through the mouth of a standard soda bottle, thus converting the bottle into a multi functional & waterproof solar powered lantern.
Contra Rotating Wind Generator
Mellowcabs manufactures and operates attractive, electrically assisted, three-wheeled pedicabs. Mellowcabs are public transport vehicles, providing first and last mile transport services. The main source of income is not from carrying passengers but rather through selling advertising space on and in the vehicles. Mellowcabs have been designed to be very safe and extremely visible, and to offer optimum advertising space on an aesthetically pleasing design.
Aquatech by Miqube is a design for a highly portable, modular, eco-friendly, habitable survival module that will enable its users to easily transport, deploy and install a unit that is able to support their living needs in terms of energy, water and sanitation, without any dependence on infrastructure.
The SunGenius is a built-in solar oven mounted on a fixed structure on the north facing wall of a house in such a way that it forms a channel from the inside of the house to the inside of the oven.
Khaya Power Pack
The Khaya Power Pack (KPP) is the central component of a low-cost, convenient power system for areas with no grid electricity supply. Key system components include: * The Khaya Power Pack, a portable rechargeable battery designed to be sturdy and have a low potential for abuse. The battery itself can neither be over discharged nor quickly drained, because the Protection System prevents this.
