Municipalities in developing countries are increasingly producing solid and liquid wastes. The management of those waste are relevant because of their impact to the environment and health. For instance, disposing waste in surrounding areas become vectors for the development of diseases, and they contribute to produce lixiviates which are already infiltrating into the water table. In addition, solid waste accounts for 5% of the total GHG emission. This becomes an environmental issue that has to be resolved.
Production of electricity from waste has the potential of providing up to 83.8 TeraWatt hours, which is about 20% of the electricity needed in Africa by 2025. This is according to a study co-authored by the European Commission Joint Research Centre. However, this requires stringent waste management policies to be put in place, and today Africa lacks the adequate infrastructure needed to install these environmentally friendly methods.
Keith White is the founder and CEO of Ambient Water, an atmospheric water generation technology company providing solutions that produce water from the humidity in the air. Its flagship systems include the Ambient Water 400, which is capable of producing up to 1,500 liters of clean water per day. Angela McClowry from Cleanleap, recently interviewed Keith to discuss atmospheric water generation and its role in a cleanleap.
A common characteristic of informal settlements in Cameroon is the lack of indoor lighting during the day. To carry out any productive activities, households have to turn on the lights – for those who can afford electricity - or use kerosene lamps or candles adding to their electricity consumption and accompanying energy-related expenses as well as indoor air pollution. This gadget is an innovative passive lighting technology based on a transparent plastic bottle filled with clean water. It is fitted into the corrugated iron roofs of houses without ceilings.
Orphfund is a small hardworking NGO where 100% of funds given go directly to their projects within Africa and Asia. Their focus is on helping children who are in the most need, orphans with no-one to care for them. They do this by building and developing Children's Villages which offer housing, schooling, water, sanitation, and training facilities. Working in areas like Sierra Leone Orphfund employ a number of cleanleap technologies to provide basic services like water and sanitation, through to solar power used to teach the children computers and sewing, through to farming to generate food and income.
Sac-marmite is an insulated bag into which the food in a pot heated on a stove, continues to cook, while the stove is no longer in use. It is made from poly-cotton fabric and polystyrene balls, rice peels or cotton as an insulator. People can cook anything from meaty stews or vegetable curries to simple rice and soups. Cooking with sac-marmite is easy and simple.
Huge dams have been touted as effective in providing drinking and irrigation water, all cheaply and sustainably. Recent studies reveal otherwise as most of these projects in sub-Sahara turn out to be more costly than planned. A recent study has quantified claims that large dams also lead to more malaria being spread in the sub-Saharan, thus adding more weight to concerns on whether these projects should be pursued actively in favor of the alternatives.
Solar power is about more than lighting your home… Regular access to hot water for bathing, cooking, and cleaning is something that most of us in the Western world take for granted. However, people in rural communities throughout the world struggle to safely and economically heat their water on a regular basis. Solar hot water systems offer a sustainable and low cost solution to this widespread issue, with the potential to bring hot water to those who do not currently have it.
Long Sokhon is a small-scale farmer in Cambodia’s Pursat Province. Like 85% of Cambodians, she makes a modest living off the land. She used to cook for her family of eight over a wood-chip fire by night. Sokhon lived the way most do in rural Cambodia—one of the poorest countries in South East Asia with a population of 15.8 million. Then, she was given the opportunity to have a 2,000 litre slate-grey tank installed in the vegetable patch. Long Sokhon was chosen as part of a biodigester pilot project run by Engineers Without Borders Australia and Live & Learn Environmental Education.
Nick Boerema is the Facilitator for Engineers Without Border’s Sanitation in Challenging Environments project and is based in Phnom Penh, Cambodia. Nick’s role includes providing technical advice on sanitation solutions and facilitating collaborative efforts to promote knowledge dissemination, innovation and adoption of best practice for sanitation in challenging environments. Nick previously worked in Australia as a project engineer for Vast Solar, managing the development and demonstration of low-cost concentrating solar thermal technology for power generation. Cleanleap's Angela McClowry recently interviewed Nick to better understand some of the challenges in sanitation and ways in which we can 'cleanleap' over existing issues.
