The demand for high-efficiency, low-energy consumption materials, with high durability and stability, has led to the rapid increase of prices Rare Earth Elements (REE). REE monopoly some countries held shift humanity towards sustainability renewable energy sources back. isolation, recovery, recycle from waste electric electronic equipment (WEEE) constitute disengagement strategy can lead signif...

Food and beverage production is an industry with the main raw materials generally obtained from plant and animal sources and the industry has always aimed to convert these raw materials to a value added products. During this conversion processes, voluminous and serious amounts of food wastes and by-products are generated. Unfortunately, one-third of the global food production is wasted worldwid...

The production of waste has increased over the years and, lacking a recycle or recovery solution, it is forwarded to landfill. The incorporation of wastes in cement-based materials is a solution to reduce waste deposition. In this regard, some researchers have been studying the incorporation of wastes with different functions: aggregate, binder and addition. The incorporation of wastes should t...

Accumulation of sawdust and sugarcane bagasse can cause serious problems for the environment. In this study, we examined the growth and reproductive performance of Eisenia foetida in cow manure, cow manure + sugarcane bagasse (4:1, V/V) and cow manure + sawdust (4:1, V/V) waste and its effects on CO2 evolution. The results showed that the weight gain for E. foetida (live weight) per gram of dry...

Increased municipal solid waste generated worldwide combined with substantial demand for renewable energy has prompted testing and deployment of woody feedstock production systems that reuse and recycle wastewaters as irrigation and fertilization. Populus selections are ideal for such systems given their fast growth, extensive root systems, and high water usage rates. Maintaining ecological sus...

Governments and co-operations are aware of the fact that more sustainable consumption and production practices are required. Efforts are being made to produce less waste while increasing the recycling ratio. Concurrently, it is of importance to place landfilling in a sustainable context. The present paper discusses a novel concept where a landfill is no longer considered as a final solution but...

Mud Recycle is a process option for cane diffuser factories; it eliminates the need for a filter station by using the bed of shredded cane in the diffuser to separate out mud solids from the juice. This paper describes the Mud Recycle system at Maidstone mill and presents the results of a Mud Recycle trial that was carried out during the 1998 season. Maidstone switched to Mud Recycle on a perma...

In the industrial production of penicillin V, the phenoxyacetate precursor is added to the fermentor to direct biosynthesis. When used for producing semisynthetic penicillins, the penicillin V is often hydrolyzed to 6-aminopenicillanic acid with the regeneration of the phenoxyacetate precursor. To reduce raw-material as well as waste-disposal costs, it is desirable to recycle the phenoxyacetate...

The waste that arrives at MBA Polymers’ big blue factory in Worksop, in England’s industrial heartland, is a dirty, smelly mess. Fresh from a metals recycler that has extracted hunks of steel from the crushed remains of cars and other trash, it contains many types of plastic jumbled in with carpeting, rubber, glues, bits of metal and glass, and even the occasional dead animal. Inside the cacoph...

Activated clay minerals have been widely used in the edible oil refining industry for decolorization of crude oil by adsorption, and so far many methods have been used to improve their decolorization efficiency. Herein, we successfully prepared a series of carbon/attapulgite (C/APT) composite adsorbents by a one-step in-situ carbonization process with natural starch (St) as the carbon source. I...
