LifeStraw: cambierà il mondo

 
Si tratta di una cannuccia salvavita, un depuratore portatile., inventato per eliminare tutte le malattie che si trasmettono bevendo da fonti d’acqua inquinate: malaria, tifo,colera dissenteria. Filtra l’acqua permettendo di bere anche dalle pozzanghere. Fatta in polietere , presenta un laccio per essere legata al collo. è lunga appena 30 cm e pesa circa 140gr. Ha vinto il Saatchi e Saatchi Award 2008, come idea che cambierà il mondo.

Come funziona: Non va ne ad elettricità ne si serve di batterie per funzionare. L’ acqua succhiata passa attraverso quattro filtri diversi. IL PRIMO, UN CERCHIO IN FIBRA CON FORI, LARGHI UN DECIMO DI MILLIMETRO, ELIMINA I SEDIMENTI E POLVERE. Il secondo, in poliestere, blocca i grappoli di batteri. A questo punto l’acqua entra in un comparto impregnato di iodio che uccidi i parassiti al 99%. Al quarto passagio una camera di carbone attivomblocca gli ultimi residui nocivi, migliorando odore e sapore dell’acqua . Considerando un consumo medio d’acqua di 2 litri al giorno, Lifestraw puo’ durre circa due anni.

The LifeStraw® Concept

The Millennium Development Goals (MDGs) call for a reduction of the proportion of people without sustainable access to safe drinking water by half between 1990 and 2015. Yet, an estimated 884 million people in the world, 37% of whom live in Sub-Saharan Africa, still use unimproved sources of drinking water1.

Lack of access to safe drinking water contributes to the staggering burden of diarrhoeal diseases worldwide, particularly affecting the young, the immunocompromised and the poor. Nearly one in five child deaths – about 1.5 million each year – is due to diarrhoea. Diarrhoea kills more young children than AIDS, malaria and measles combined2. Drinking contaminated water also leads to reduced personal productive time, with widespread economic effects.

Approximately 43% of the global population, especially the lower-income populace in the remote and rural parts of the developing world, is deprived of household safe piped water. Thus, there is a pressing need for effective and affordable options for obtaining safe drinking water at home. Point-of-use (POU) treatment is an alternative approach, which can accelerate the health gains associated with the provision of safe drinking water to the at-risk populations. It empowers people to control the quality of their drinking water. Treating water at the household level or other point of use also reduces the risk of waterborne disease arising from recontamination during collection, transport, and use in the home, a well-known cause of water-quality degradation3. In many rural and urban areas of the developing world, household water-quality interventions can reduce diarrhoea morbidity by more than 40%4,5. Treating water in the home offers the opportunity for significant health gains at potentially dramatic cost savings over conventional improvements in water supplies, such as piped water connections to households6.

Water filters have been shown to be the most effective interventions amongst all point-of-use water treatment methods for reducing diarrhoeal diseases7. The Cochrane review demonstrates that it is not enough to treat water at the point-of-source; it must also be made safe at the point-of-consumption.

LifeStraw® and LifeStraw® Family are both point-of-use water interventions – truly unique offerings from Vestergaard Frandsen that address the concern for affordably obtaining safe drinking water at home and outside. These complementary safe water tools have the potential to accelerate progress towards the MDG target of providing access to safe drinking water, which would yield health and economic benefits; thus contributing to the achievement of other MDGs like poverty reduction, childhood survival, school attendance, gender equality and environment sustainability.
