O livro avançado neste estudo é a atual questão da ética ambiental local e global nas políticas de desenvolvimento de produtos no âmbito das exigências cada vez maiores dos clientes. O estudo explora a atual necessidade urgente de estruturas adequadas de conceção de produtos, ferramentas práticas e consciência ecológica entre as partes interessadas no processo de conceção de produtos e ao longo de todo o ciclo de vida do produto. A literatura existente denuncia o atual estado deplorável do ambiente global e os seus inúmeros efeitos na saúde, no habitat e nas gerações futuras. Aponta também para a grande preocupação global com o ambiente e para os esforços de indivíduos, governos e agências internacionais para mitigar estes efeitos adversos. A literatura também faz uma repartição dos métodos atualmente disponíveis para assimilar os aspectos ambientais na conceção dos produtos e no seu ciclo de vida. No que se refere à situação no Quénia, a literatura disponível denuncia a incapacidade e a apatia na abordagem das questões ambientais e documenta a crise crescente de amontoados aleatórios de resíduos sólidos. O estudo destaca estes amontoados crescentes de resíduos depositados ilegalmente e os seus efeitos ecológicos no ambiente em que vivemos.

PrefaceIn the engineering and design professions, the study of materials is a huge prerequisite to competence and success of projects. It is therefore imperative on practitioners and students to acquaint themselves with the myriad of materials available for application to projects. The book on "DESIGN MATERIALS AND PROCESSESVOLUME 4" covers selected topics on individual materials to meet such needs. It endeavours to look into the history and processes of the identified materials. Applications and classification of the materials was approached from their sources, i.e. metals, polymerics, ceramics and composites. Where possible, diagrams are complemented by photographs to impart clarity to the topics.While looking at materials from an engineering and design perspective, it is not lost to the author the need to entertain the leisure reader as well. Meant for college and university students, the layout and language is intentionally simple enough to be understood by even the leisure reader. The reader will find this book invaluable for all the reasons and needs enumerated above. It is hoped that by the end of such readership, they will gather the necessary knowledge on types of materials, their history and discovery, their processing process, their different types and their applications. Finally, the authors aim is to assist the reader in identifying the materials, using the materials, applying the materials and recommending them to clients/projects appropriately.
