<p>"Zero Emissions" has become a definitive term in the debate on sustainable development in the last few years. While considered a utopian target by some, the concept clearly describes what business and industry of the future must aim to achieve. There is no confusion here; the aim is transparent: no pollution and no waste.</p><p>Only when industry mimics nature, where nothing is wasted, can it achieve the same levels of material productivity. The world of waste is a world of opportunity. A world where the waste from one process can become the raw material for another—a cascade of new materials once thought worthless supporting new products, new processes and new wealth—as industries that were previously considered unrelated cluster together. A world where new business will be created on an unprecedented scale. This is not just a theory: projects in the agro-business, based on integrated biosystems, are already up and have proved effective.</p><p><em>Upsizing</em> examines how the adoption of the Zero Emissions concept not only radically reduces pollution and waste but can contribute significantly to the generation of income and jobs - specifically for those that need them most: the rural poor in less developed countries.</p>
