There is an increasing awareness that materials and chemicals produced from fossil fuels are not sustainable, both in terms of the pollution caused by the extraction and production processes, and the fact that there is only a finite supply of these fossil fuels. Therefore, there is a strong incentive to find sources for chemicals and materials from source materials that we know we can continue to generate. Plants are a source of a wide variety of chemicals, many with interesting properties, and these chemical feedstocks are considered renewable rather than finite.Green Chemistry and Green Materials from Plant Oils and Natural Acids covers the application of these natural materials in producing polymers, lubricants and plasticisers.

Crop losses due to insect pests can be economically devastating to farmers and lead to the risk of food shortages. Pest-vectored disease can cause significant economic shortfalls and decimate public health by causing significant morbidity and mortality, especially in economically disadvantaged populations and those in neglected, developing regions. Traditionally, synthetic pesticides have been utilized to reduce these grave agricultural and public health concerns. However, pesticide overuse and misuse have led to widespread pesticide resistance and select environmental impacts that limit their long-term utility. Therefore, it is necessary to find new control approaches and chemistries that can reduce pest pressure sustainably without adverse environmental impacts.Green Chemistry for Pest Management addresses the known examples of utilizing natural chemistry and other non-traditional methods to control pest insects, plants and rodents. Natural pesticides from plant, microbiological and animal sources are discussed, as is the use of natural products as lead compounds for the synthesis of biorational and semisynthetic pesticides.

Finding alternatives to fossil feedstocks is increasing in importance with the challenges of global warming, increasing oil prices and depleting fossil fuel reserves that we currently face. Today, plant oils are important renewable raw materials for the chemical industry and are heavily used for surfactants, cosmetic products and lubricants.This book covers the green chemistry of products and intermediates synthesised from plant oils. Photo-initiated polymerisation and polymerization of vegetable oils in environmental media are covered as well as click reactions to chemically modify vegetable oils. Useful products from plant oils such as polymers, biomaterials, biofibres and lubricants, as well as their further applications, are described.This book is a valuable resource for researchers in academia and industry, biomass producers and suppliers and manufacturers of end-products.
