Handbook of Innovative Adhesive Technology
The environmental impact of the common binders used in construction materials is usually evaluated through life-cycle assessment (LCA), which is an effective process to measure the service life of construction materials. As construction materials are wood-based, they need flame retardants and various other additives to develop the desired features, which are added during the manufacturing process of construction materials. This makes the materials less environment-friendly and greenhouse gas emitters. The LCA of construction materials made of biodegradable binders, such as starch (flour-, corn-, and potato-based starch), and fibers, such as oat, hemp, and flax shives, has shown that they hav...
Eco-Enzyme Hand Sanitizer Dari Limbah Wortel dan Bunga Melati
Pengelolaan limbah wortel merupakan tantangan yang sering dihadapi dalam industri pertanian. Limbah wortel yang dihasilkan dalam jumlah besar dapat menjadi beban lingkungan jika tidak dikelola dengan baik. Namun, dengan mengubah limbah wortel menjadi bahan baku untuk Eco-enzyme hand sanitizer, permasalahan pengelolaan limbah dapat diatasi dengan cara yang kreatif. Proses fermentasi limbah wortel menjadi Eco-enzyme memberikan manfaat tambahan dalam bentuk efek antiseptik alami. Penambahan ekstrak melati dalam Eco-enzyme hand sanitizer memberikan manfaat tambahan dalam hal efek antiseptik alami. Meskipun menggunakan bahan-bahan alami, keamanan dan efektivitas dari Eco-enzyme hand sanitizer per...
Feedstock Recycling and Pyrolysis of Waste Plastics
Pyrolysis is a recycling technique converting plastic waste into fuels, monomers, or other valuable materials by thermal and catalytic cracking processes. It allows the treatment of mixed, unwashed plastic wastes. For many years research has been carried out on thermally converting waste plastics into useful hydrocarbons liquids such as crude oil and diesel fuel. Recently the technology has matured to the point where commercial plants are now available. Pyrolysis recycling of mixed waste plastics into generator and transportation fuels is seen as the answer for recovering value from unwashed, mixed plastics and achieving their desired diversion from landfill. This book provides an overview of the science and technology of pyrolysis of waste plastics. It describes the types of plastics that are suitable for pyrolysis recycling, the mechanism of pyrolytic degradation of various plastics, characterization of the pyrolysis products and details of commercially mature pyrolysis technologies. This book also covers co-pyrolysis technology, including: waste plastic/waste oil, waste plastics/coal, and waste plastics/rubber.
