THE ASSESSEMENT OF DANGEROUSNESS OF WASTE. CASE STUDY: WASTE ORIGINATING FROM DRILLING MUDS

This paper continues the presentation of the case studies on waste dangerousness assessment. Due to the particularities that shows many of the waste generated in industry, in particular, each analysis represents a special case. The application of the methodology for determining the dangerousness of waste (carried out and used by our institute, still in the absence of rules for the implementation of legislation on waste management), often faces challenges regarding the estimation (with an error as low as possible) of the concentration for the potential components from the waste, necessary to establish the hazardous/non-hazardous character of the waste and, implicitly, for its correct classification in the waste list. In this respect, the case study presented is that of a waste from drilling muds.

EXPERIMENTAL MODELS OF CHARACTERIZATION AND ANALYSIS OF INDUSTRIAL WASTE

In the present paper we report, a series of experimental characterization and analysis models that can be applied to industrial waste samples in order to determine the heavy metals within them. During our studies we determined that both preparation and pretreatment of the waste sample are the two most important steps in the analysis process. Therefore, an increased attention was given in using appropriate procedures and methods for preparation and pretreatment. In order to ensure a correct and secure analysis were developed experimental models based on preparation and pretreatment stages and also on organic matrix decomposition method (digestion process with acid mixture under microwave). These experimental models were tested on a series of wastes coming from processing and finishing activities of metal surfaces and other materials. Metal concentration was analyzed by AAS (atomic absorption spectrometry) and XRF (X-ray fluorescence spectrometry). The obtained results proved that the proposed experimental models are suitable for analysis of different types of industrial wastes samples.

ECOLIB, LIBRARY OF NATIONAL R&D INSTITUTE FOR INDUSTRIAL ECOLOGY, AN ON-LINE TOOL FOR ENVIRONMENTAL TOPICS AREA

Digital Repository of National Research and Development Institute for Industrial Ecology ECOIND, library was launched on the end of April 2017. ECOLIB Repository is structered in six communities, as follows: Ecology and Pollution Control; Environmental Assessment; Environmental Technologies; Environmental Management; Other Topics; SIMI Proceedings (International Symposium „The Environment and The Industry”: editions 2011, 2013, 2015, 2016). First four communities, representing the main research areas of ECOIND, contains articles authored by ECOIND researchers published in national and international journals, doctoral theses (abstract), conference papers, short description of the projects developed from 2006 till present, patents. The repository contains more than 800 documents, 850 author names, 1750 keywords. The research results presented within repository documents are related to development / implementation of the analytical control methods used to assess environmental pollution level (water, soil, sediments, air, waste products); ecotoxicological assessment studies for chemicals / polluted environmental samples regarding their biodegradability, acute and chronic toxicity on different aquatic organisms (fish, green algae, planktonic and benthic crustacean, rotifers, ciliates, plants and bacteria); modern procedures applied for advanced removal of dangerous compounds from water; technologies / biotechnologies applied for water treatment, clean technologies with low energy inputs, innovative biotechnologies presenting unconventional treatment processes; evaluation of the ecological risk determined on the environment (covering water, air, and soil components); industrial waste management– development of advanced methodologies for identification and assessment of the environmental risks caused by waste disposal; methodologies in the fields of quality management, environmental management, and health and occupational safety management.

Environmental risk assessment a practical approach in case of specific activities to locomotives maintenance and exploitation

The paper shows a case study of environmental risk assessment generated in the area of development of specific activities to locomotives maintenance and exploitation. The analysis involves accumulating large volumes of information, processing, organizing and interpreting them in the context of the problems analyzed. The elements related to the nature and intensity of pollution, migration and transport pathways of specific pollutants are presented. As a result of investigations carried out on site soil / subsoil and groundwater have been able to identify and delimit areas of significant pollution. From the analysis the distribution maps of the THP contents, carried out on the analytical data obtained from characterization samples of soil, pollutant migration in a horizontal plane was highlighted
