in this study, the recovery of casing soil consumed in the white button mushroom was investigated. casing soil is used as a layer on compost (culture medium) to a diameter of 3-5to stimulate fruiting on the white button mushroom(agaricus bisporus) . the expense od casing soil is about 30 percent of production costs. in the first step of this experiment, in order to separate casing soil from com...

Construction and demolition waste (CDW) constitutes an increasingly significant problem in society due to the volume generated, rendering sustainable management and disposal problematic. The aim of this study is to identify a possible reuse option in the concrete manufacturing for recycled aggregates with a significant ceramic content: mixed recycled aggregates (MixRA) and ceramic recycled aggr...

-Utilization of construction debris as recycled aggregates in the production of concrete is gaining momentum nowadays due to the availability of large quantity of demolition waste. The recycled brick aggregate (RBA) concrete is made used for the production of low grade recycled aggregate suitable for concrete production. The risk of concrete structures exposed to fire is also on the increase du...

The need for effective apparel waste management is motivated by the increasing cost and decreasing availability of landfill space and the dwindling of natural resources. The aim of this study was to identify the current solid waste disposal and recycling practices of the apparel industry in South Africa and to determine their attitude and willingness towards recycling, their perception of the f...

The ability of polypeptide components of eukaryotic initiation factor (eIF) 4F to bind to the m7G cap of an mRNA, to be released from that mRNA, and then to rebind to the cap of a second mRNA has been investigated. The release and rebinding steps have been termed "recycling." It was found that eIF-4B stimulates the recycling of the 24-26 kDa (p24) component of eIF-4F, and perhaps of other compo...

In this work, an antimicrobial guanidine polymer (PHGH) was grafted onto starch as a carrier to form branched or grafted chains along the starch backbone. This grafting improved the antimicrobial properties and the adsorption of the starch on recycled cellulose fibers. Similar work was also conducted on bleached sulfite fibers for comparison. The results showed that the starch, grafted with 12 ...

We show that a family of quantum authentication protocols introduced in [Barnum et al., FOCS 2002] can be used to construct a secure quantum channel and additionally recycle all of the secret key if the message is successfully authenticated, and recycle part of the key if tampering is detected. We give a full security proof that constructs the secure channel given only insecure noisy channels a...

Both environmental and economic factors have driven the development of recycling routes for the increasing amount of carbon fibre reinforced polymer (CFRP) waste generated. This paper presents a review of the current status and outlook of CFRP recycling operations, focusing on state-of-the-art fibre reclamation and re-manufacturing processes, and on the commercialisation and potential applicati...

This study aims to conduct research about the microstructure and basic properties of recycled aggregate concrete under seawater corrosion. Concrete specimens were fabricated and tested with different replacement percentages of 0%, 30%, and 60% after immersing in seawater for 4, 8, 12, and 16 months, respectively. The basic properties of recycled aggregate concrete (RAC) including the compressiv...
