Host Rocks

The conditions in the crystalline geological massif, which determine the long-term safety of radioactive waste disposal, are reduced to two fundamental factors - the features of the host rocks and the fracture network inherent in the studied area of the massif [3]. Refinement of the parameters identified at the early stages of geological study of cracks is one of the highest priority tasks in the safety assessments of the radioactive waste disposal. These parameters should also be taken into account in the formation of requirements for the composition and structure of the system of engineering barriers preventing the release of radionuclides outside the disposal. The presented material contains a description of the work and the approaches applied in processing the results of borehole surveys of the prospecting and appraisal stages of geological exploration of the Yeniseisky area, performed using the specialized probe with video logging equipment.

Pulp Production

The use of recovered paper as a raw material for paper production is by far the most economical and ecological strategy for the disposal of waste paper. However, paper production from recovered paper furnish generates a great amount of residues, and the higher the demand requirements for the end product, the higher the amount of rejected material. The reason for this is that the selectivity of the deinking process is limited; therefore, some valuable components are also lost in reject streams. The rejection of usable components affects the economics of recycled paper production. As the cost of waste disposal continues to increase, this issue is becoming more and more severe. This paper summarizes the current state of the resource efficiency in recycled pulp production and provides information on the volumes of rejected streams and the usable material within them. Various means to use these reject streams are also discussed, including the main findings of a recent thesis by the main author. This review summarizes current internal and external use of reject streams generated in the deinking operations.
