Item type:Article, Access status: Open Access , Wprowadzenie do oceny cyklu życia (LCA) - nowej techniki w ochronie środowiska(Wydawnictwa AGH, 2006) Grzesik, KatarzynaThe aim of Life Cycle Assessment is studying the environmental impacts associated with a product, throughout the whole product's life, »from cradle to grave«, including raw material acquisition, raw material treatment, production process, transportation, distribution, usage, reuse, recycling, and ultimate waste disposal. LCA technique includes 4 phases, which are described in detail in this paper. These phases are: definition of goal and scope, life cycle inventory analysis of inputs and outputs (LCI), life cycle impact assessment (LCIA) and interpretation of analysis results in reference to goal of the study. LCA involves complex interactions between product (service) and the environment. The study should address the potential impact to human health, resource depletion and ecosystem health. The purpose of LCA is identifying the product or process, which is the least harmful to the environment, setting the priorities in product development and identifying the transfer of environmental impact from one media to another. The strategy of implementing in Poland the Integrated Product Policy was amended in February 2005. This strategy concentrates on minimizing the environmental impact of products in all phases of theirs life. This aim should be based on knowledge, delivered by widely and systematically used the life cycle assessment.Item type:Article, Access status: Open Access , System gospodarowania olejami odpadowymi na terenie województwa podkarpackiego(Wydawnictwa AGH, 2005) Przewoźnik, Dorota; Grzesik, KatarzynaThe current situation in waste oil management system in Podkarpacki region was presented in the article. The volume of produced waste oils along with perspective future figures till the year 2014 were taken into account. The collection system of waste oils as well as the technology of oil recycling were described in detail. Consortium of Waste Oils is one of the most resiliently functioning Polish organizations in respect of a collection and recycling of used oils. This organization was established on the basis of Jedlicze Refinery (Podkarpacki region). The Consortium elaborated a concept of nationwide integrated network of collection and recycling of waste oils. This concept assumes a cooperation with local authorities. A collection of oils from dispersed and small sources can be implemented on the level of gmina (lowest level of local authority in Poland) in so-called Hazardous Waste Collection Points. Oil Refinery in Jedlicze operates an installation designed for initial refining and distilling waste oils. Collected oils are subject of refining through decantation process followed by distilling. Re-refining process is the next step of oil recycling. A modern process of waste oils recycling, complying with obligatory procedures of waste treatment is applied in Jedlicze Refinery. Recycling of waste oils results in many benefits - ecological, energetic, economic and fuel ones.
