Secondary resources of tomato processing as a valuable raw material for obtaining food ingredients

Obtaining raw material: plants as tool sources for Nigerian chimpanzees.

We investigated the acquisition of plant materials from which Nigerian chimpanzees manufacture wooden tools to harvest insects and honey from nests of army ants, honey bees and stingless bees. Slender trunks of juvenile trees and branches are most commonly used, and bendable vines rarely, probably reflecting the need to work with relatively sturdy tools to extract resources. While several tools...

Generic Plan of Food Safety Management System Based on ISO 22000:2005 for Aflatoxin Control in Raw Pistachio Processing Units from Raw Material Reception to Packaging

Pistachio is one of the most important agricultural crops of Iran. It is a nut from Anacardiacea family and its domesticated species is called Pistacia vera L. Regarding to pistachio importance and usage and by the expanding of pistachio cultivate, it is necessary to improve agricultural situation and by establishing well equipped processing and packaging units near the farms, it is possible to...

Ash from thermal power plants as secondary raw material.

The basic characteristic of thermal power plants in the Republic of Serbia is that they use low-grade brown coal (lignite) as a fuel. Depending on the location of coal mines, lignite may have different properties such as heating value, moisture, and mineral content, resulting in different residue upon combustion. Because of several million tonnes of ash and slag generated every year, their gran...

Mineral Processing Mineral , renewable and secondary raw material processing – current engineering challenges

A hazardous waste from secondary aluminium metallurgy as a new raw material for calcium aluminate glasses.

A solid waste coming from the secondary aluminium industry was successfully vitrified in the ternary CaO-Al(2)O(3)-SiO(2) system at 1500 degrees C. This waste is a complex material which is considered hazardous because of its behaviour in the presence of water or moisture. In these conditions, the dust can generate gases such as H(2), NH(3), CH(4), H(2)S, along with heat and potential aluminoth...
