A large number of tanneries and leather product manufacturers are facing serious problemsregarding waste disposal, the more so as their storage in landfills leads to negative effects on theecosystem. Using tanned waste is of particular interest because it offers the opportunity toeliminate all wastes from tanning, while obtaining qualitatively and economically valuableproducts. Organic biopolymers represent a source of raw material for agriculture, because thecomposition of protean wastes provides enough elements to improve composition andrehabilitation of degraded soils, and plants can capitalize some elements: nitrogen, calcium,magnesium, sodium, potassium, titanium etc. The wastes used for this innovative procedure forobtaining biopolymers, are obtained from wet white tanned leather through a new technique basedon Ti-Al tanning agents. The work presents a new pilot technology for biochemical decay of thetannery protein wastes and use of the resulted products as fertilizers. Source

Following the accident at the nuclear power plant in Chernobyl a number of different remedial actions were developed and implemented in Belarus, Russia, and Ukraine. Recommendations on the application of countermeasures and remedial actions were published by the IAEA as "Guidelines for agricultural countermeasures following an accidental release of radionuclides" in 1994. Since then, new information on the behaviour of radionuclides in the environment and effectiveness of countermeasures in the long term has been obtained and reviewed by many projects, including the Chernobyl Forum. Additionally, new approaches to derive remediation strategies were developed and successfully implemented in the most affected countries. This paper describes a justification of the remediation strategies suggested for rehabilitation of the areas most affected by the Chernobyl accident based on this experience. © 2010 Elsevier Ltd.

Radioactive contamination of the environment following the Chernobyl accident still provide a substantial impact on the population of affected territories in Belarus, Russia, and Ukraine. Reduction of population exposure can be achieved by performing remediation activities in these areas. Resulting from the IAEA Technical Co-operation Projects with these countries, the program ReSCA (Remediation Strategies after the Chernobyl Accident) has been developed to provide assistance to decision makers and to facilitate a selection of an optimized remediation strategy in rural settlements. The paper provides in-depth description of the program, its algorithm, and structure. © 2010 Springer-Verlag. Source

The paper presents the process of developing long-term action bioenhancers from protein waste originating from tanneries and their application in agriculture for plant growth and remediation of degraded soils. Conditioning the soil consists in improving the physical characteristics through the use of substances of various origins, known in the literature as soil conditioners – soil conditioning agents. The main objective of the paper is to improve soil structure on the surface of the germinative bed using multi-compound systems of biopolymers and thus providing better conditions for plant spring, growth and development, especially in species in which seed is inserted into the soil at shallow depth (up to 4 cm) and using structurally stabilized soil. The aim was to obtain state-of-the-art bioenhancers, with the mission of potentiating the transfer of nutrients obtained by means of the protein fertilizer to the plant and fruit, resulting in metabolism stimulation, speeding the productive phase, stimulation of the plant's self-defense system and optimization of mechanisms responsible for the health of fruits. The most remarkable advantage of using protein bioenhancers, obtained from protein waste is the positive impact on the development and health of the plant, as well as on its resistance to stress factors (drought, salts and pesticides). After the experiments, it can be concluded that protean bioenhancers samples gave good results both in terms of improving soil quality, and plant growth in high culture. © SGEM2015. Source

This paper is a synthesis of innovative approaches and the results obtained in their research projects in Romania. The results presented refer to the completion of the reference database in the soil physics domain because the air permeability of soils was only partially studied and researched. In addition, this paper further asserted experiments on soil aeration process treated with processed organic compost and the importance of air in the soil. To achieve the objectives of the work case studies were conducted, cases which took into account both air movement in the soil, characterization based on the determination of soil permeability to air, and air content in pilot experimental blocks. The data obtained were used for unifying methodology for the Soil Monitoring System in Romania with a physical assimilation of extreme importance that provides clear indications on irrigation hidromodule and drainage of agricultural land. © SGEM2015.
