Renewable fuels, in the present times, have become important to curb emission of greenhouse gases, which are causing damage to the environment and leading to climatic changes. Ideally, their utilization can be a zero carbon operation. Planting suitable trees on all waste lands and agro forestry on a large scale can fulfil the needs of timber, fuel, fruits, etc. All kinds of lignocellulosic biomass can be converted by several methods to useful liquid fuels like alcohols, biodiesel, methane, renewable diesel and renewable gasoline. Hydrogen can be used as a renewable fuel because of its desirable characteristics and properties for its use as a green fuel.
Pembangunan dunia yang begitu pesat telah menyebabkan peningkatan pencemaran alam sekitar, terutamanya pencemaran udara yang telah memberikan pelbagai kesan negatif. Sehubungan ini kawalan pencemaran udara perlu diusahakan dan dipertingkatkan untuk mencegah pembebasan bahan pencemar berbahaya ke dalam atmosfera. Pengetahuan tentang bahan pencemar, konsep metereologi dan isu pencemaran udara dan iklim sejagat semestinya perlu difahami terlebih dahulu, diikuti kaedah pengukuran kadar pembebasan bahan pencemar serta perkembangan teknologi terkini bagi merealisasikan usaha ini. Senario pencemaran udara ini juga perlu dilihat daripada aspek undang-undang dan peraturan kawalan udara. Buku Pengenalan Kepada Pencemaran Udara ini amat sesuai dijadikan rujukan dan panduan para pelajar, jurutera dan mereka yang berminat tentang masalah dan kawalan pencemaran udara. Gaya penyampaian buku yang ringkas namun padat sememangnya menjadi hasrat penulis agar memudahkan pemahaman pembaca. Kes kajian bahan pencemar daripada sektor tenaga, iaitu arang batu turut dibincangkan untuk memberi gambaran sebenar tentang situasi yang berlaku.

This book focuses on the development of biodiesel systems from the production of feedstocks and their processing technologies to the comprehensive applications of both by-products and biodiesel. It should be of interest for students, researchers, scientists and technologists.
This book includes 19 chapters contributed by the world's leading experts on pretreatment methods for biomass. It extensively covers the different types of biomass (e.g. molasses, sugar beet pulp, cheese whey, sugarcane residues, palm waste, vegetable oil, straws, stalks and wood), various pretreatment approaches (e.g. physical, thermal, chemical, physicochemical and biological) and methods that show the subsequent production of biofuels and chemicals such as sugars, ethanol, extracellular polysaccharides, biodiesel, gas and oil. In addition to traditional methods such as steam, hot-water, hydrothermal, diluted-acid, organosolv, ozonolysis, sulfite, milling, fungal and bacterial, microwave, ...
Emerging Methods for Oil Extraction from Food Processing Waste is a comprehensive and cutting-edge exploration of sustainable oil extraction practices, catering to professionals and researchers in food science. The book, spanning 13 insightful chapters, intricately reviews the extraction of oil from food processing by-products, including pomace and surplus raw materials. It specifically focuses on emerging non-thermal technologies, offering valuable insights into improving oil extraction rates. The discussions encompass factors influencing extraction rates and suggest processing conditions based on various extraction methods and raw materials. In addition to providing a nuanced understanding...
This volume investigates the applications of the Circular Economy (CE) model in addressing the burgeoning issue of waste. Today, it has become imperative to understand the problem of environmental pollution from a value chain perspective. This calls for the coupling of the knowledge bases of science and management to achieve practical solutions to environmental problems and transition to a low carbon economy. With this thought process, this book merges various concepts from the techno-managerial perspective for effective waste management solutions. It throws light on the system-oriented view of CE and the contributions explore such concepts as the managerial aspect of waste management and CE, as well as advances in technical detailing.
This book covers sustainable recycling processes (e.g. physical, biological, chemical, and thermo-chemical) of multiple organic solid wastes, provides methods for material recycle of wastes into value-added products including fuels and commodity chemicals that are able to be directly applied to promote manufacturing processes. Aimed at improving the awareness of effective conversion protocols and for developing innovative biomass conversion processes, this text was conceived as a collection of studies on state-of-art techniques and know-how for production of biofuels and chemicals from sustainable recycling of organic solid wastes. Topics in the text are discussed in terms of addressing recent advances, assessing and highlighting promising new methods or new technological strategies and direct conversion of organic solid wastes to process feeds. Highly-recognized authorities, experts and professionals have contributed individual chapters in selected areas to cover the overall topic in a comprehensive manner.

Supply and demand of resources are connected in multiple and complex ways. This interconnectivity has been framed as the global resource nexus. This study focuses on the nexus of five essential natural resources: land, food, energy, water, and minerals. In order to meet the demand for resources from present and future generations, strategic thinking about interdependencies between the supply of and demand for resources is paramount. This report provides insight into the complex interaction between resource supply and demand, global megatrends such as economic growth, climate change, urbanization and demographics, and broader nexus variables such as human resources, technology, governance, so...
