Global population by 2050 is predicted to be over 9 billion and accordingly, the production systems will demolish about 140 billion tons per year of minerals, ores, fossil fuels and biomass, i.e., thrice of the current need, and the food production itself has to be doubled. Optimized resource usage, lifecycle management, and reduced carbon emission have become a priority for agri-food businesses today, and circular economy (CE) helps for a sustainable and flexible way to grow without exhausting primary materials, and it thinks beyond recycling and resource usage. The word CE best relates to the resource and efficiency management, 6Rs, closed-loop production systems, zero waste and lifecycle engineering, reduced overconsumption of resources and waste generation, enriched system redesign and business model innovation, thereby leading to sustainable development goals. In this light, the book calls for theoretical and empirically sound contributions that are focused on the different aspects of the circular economy, 6R’s, sustainable production and consumption, closed-loop systems, etc. in the agri-food sector.
Interestingly, some relief from today's woes may come from ancient human practices. While current agri-food production models rely on abundant supplies of water, energy, and arable land and generate significant greenhouse gas emissions in addition to forest and biodiversity loss, past practices point toward more affordable and sustainable paths. Different forms of insect farming and soilless crop farming, or hydroponics, have existed for centuries. In this report the authors make a persuasive case that frontier agriculture, particularly insect and hydroponic farming, can complement conventional agriculture. Both technologies reuse society's agricultural and organic industrial waste to produce nutritious food and animal feed without continuing to deplete the planet's land and water resources, thereby converting the world's wasteful linear food economy into a sustainable, circular food economy. As the report shows, insect and hydroponic farming can create jobs, diversify livelihoods, improve nutrition, and provide many other benefits in African and fragile, conflict-affected countries. Together with other investments in climate-smart agriculture, such as trees on farms, alternate wetting and drying rice systems, conservation agriculture, and sustainable livestock, these technologies are part of a promising menu of solutions that can help countries move their land, food, water, and agriculture systems toward greater sustainability and reduced emissions. This is a key consideration as the World Bank renews its commitment to support countries' climate action plans. This book is the Bank's first attempt to look at insect and hydroponic farming as possible solutions to the world's climate and food and nutrition security crisis and may represent a new chapter in the Bank's evolving efforts to help feed and sustain the planet.
An important feature of the dairy cattle show ring is the opportunity it affords for inspiring the dairyman to improve his stock, by holding up to him an ideal toward which to work.
Circular economy can serve as a key building block for the sustainability targets of manufacturing companies. Although the term itself has long been established, we see that proper implementation of a circular economy model across entire manufacturing value chains is still lacking and remains a challenge for companies. However, there are clearly visible and good examples of circular economy standards which have already been applied, generating value among multiple layers. Circular Economy and Manufacturing presents these and more, providing a roadmap of optimized, flexible, efficient, effective, and competitive green production strategies for the manufacturing industry and its multiple stakeholders. The volume proves to be an excellent springboard for further discussion and research into new frameworks of best practices, in view of achieving more socially responsible and sustainable organizations in a not-so-distant future. - Helps readers to easily identify state-of-the-art advances in the circular economy as applied to the manufacturing industry - Adopts an interdisciplinary perspective, offering insights into both engineering and management components of the whole circular economy approach - Includes contributions from an internal group of experts - Presents methodologies and showcases their application through case studies
