Potentials for win-win alliances among animal agriculture and forest products industries:Application of the princi-ples of industrial ecology and sustainable development

Commercial forests in many parts of the world are deficient in nitrogen and phosphorus. These nutrient-deficient forests often exist in close proximity to large animal feeding operations, meat processing and other food, textile, or other biomass-processing plants, and municipal waste treatment facilities. Many of these facilities produce large surpluses of nitrogen,phosphorus, and organic matter as gaseous ammonia, urea, uric acid, phosphorus compounds,bacterial sludges, and partially treated municipal wastewaters. These co-existing and substantial nutrient deficiencies and surpluses offer ready-made opportunities for discovery, demonstration,and commercial development of science-based, technology-facilitated, environmentally sound,economically viable, and socially acceptable "win-win alliances" among these major industries based on the principles of industrial ecology and sustainable development. The major challenge is to discover practical means to capture the surplus nutrients and put them to work in forest stands from which value-added products can be produced and sold at a profit.

Multi-scale Approaches toward Sustainable Development

Approaches toward the sustainable development need integrated considerations of technical, economical, environmental/ecological and social issues. Current approaches from different disciplines can be grouped into at least three levels: micro-scale, meso-scale and macro-scale. At the micro-scale, green chemistry carries out chemical activities such as chemical design and synthesis so that environmentally benign chemicals can be synthesized without using and generating hazardous substances. Green engineering, at the meso-scale, develops green industrial processes or clean technologies via pollution prevention and cleaner production, which will cause minimal damages or dangers to the environment and ecosystems when the product is manufactured and used. Industrial ecology at the industrial complex or community level seeks to optimize energy and materials use and minimize waste generation in industrial systems or communities by promoting planned materials and energy exchanges. Incorporation of ecological principles with the life cycle thinking in the chemical pathway synthesis, product design, process development, and industrial system and community planning appears to be the most promising engineering approach in achieving sustainable industrial development.

Urban and Industrial Metabolism： Towards Sustainable Planning

Nowadays, urban planning supposes a key issue to promote sustainable cities＇ development. In the last decades, the urban growth of developed countries has caused several environmental, social and economic problems, such as the inefficient use of resources and infrastructures. Notwithstanding, detailed analysis of population＇s necessities allows decreasing these drawbacks. These enhancements can foster a more feasible development through technical sustainability criteria. Therefore, the urban metabolism study becomes an essential tool to plan a suitable management for material and energy flows. Industrial Ecology （IE） theory looks for the sustainable integration of human activities on their natural environment. It seeks mimic natural systems performance and their processes. Industrial Metabolism （IM） studies those processes which turns material and energy into products and wastes. The IE final goals aim to promote improvements in process efficiency, decreasing consumption and waste generation through flows recirculation and exchange networks of material and energy. This contribution proposes a new conceptual framework which integrates urban and industrial metabolisms as an opportunity to achieve more efficient and sustainable development. The review of national and international experiences shows the improvements achieved through metabolisms＇ combination based on the exchanges of residual energy and water streams.
