    Effect of Recycling on the Environmental Impact of a High-Efficiency Photovoltaic Module Combining Space-Grade Solar Cells and Optical Micro-Tracking

    This paper presents a life cycle assessment (LCA) analysis of a new, high-concentration photovoltaic (HCPV) technology developed as part of the HIPERION project of hybrid photovoltaics for efficiency record using an integrated optical technology. In the LCA calculations, the production stage of a full module was adopted as a functional unit. SimaPro version 9.00.49, the recent Ecoinvent database (3.8), and the IPCC 2021 GWP 100a environmental model were applied to perform the calculations. The environmental impact of the HCPV panel was determined for constructional data and for recycling of the main elements of the module. The results of the calculations show that recycling of PMMA, rubber, and electronic elements reduced the total carbon footprint by 17%, from 240 to 201 kg CO2-eq. The biggest environmental load was generated by the PV cells: 99.9 kg CO2eq., which corresponds to 49.8% (41.7% without recycling) of the total environmental load due to the large number of solar cells used in the construction. The emission of CO2 over a 25-year lifespan was determined from 17.1 to 23.4 g CO2-eq/kWh (20.4 to 27.9 without recycling), depending on the location. The energy payback time (EPBT) for the analyzed module is 0.87 and 1.19 years, depending on the location and the related insolation factors (Madrid: 470 kWh/m2, Lyon: 344 kWh/m2). The results of the calculations proved that the application of recycling and recovery methods for solar cells can improve the sustainability of the photovoltaic industry.

    The Use of Sequential Extraction for Assessing Environmental Risks of Waste Incineration Bottom Ash
    (Towarzystwo Chemii i Inżynierii Ekologicznej (TChiIE), 2014) Wielgosiński, Grzegorz; Wasiak, Dorota; Zawadzka, Alicja
    Thermal treatment of waste is one of the ways of their processing. It is commonly used in most developed countries of the European Union. Major by-products of the combustion processes are slag and bottom ash. In the majority of EU countries bottom ash and slag are used as a priming for road construction. In Poland slag and bottom ash from incineration process are stabilized with the addition of cement and some polymers and are landfilled as wastes. In accordance to Polish law, depending on the leaching of heavy metals from fly ash and slag after thermal treatment of waste can be regarded as both hazardous and non-hazardous wastes. At present work sequential extraction methods described in the literature: Tessier’s method, van Herck’s method and BCR method were compared experimentally with the results of using Swiss standard TVA.SA.1991 and European standard EN 12457 and total concentration of metals in sample analyzed after complete digestion of sample. The study sample was bottom ash from the medical waste incineration plant.

    The Impact of Waste Incineration on Human Beings and The Environment

    Poruszono tematykę związaną z oddziaływaniem spalarni odpadów na zdrowie osób w nich zatrudnionych oraz środowisko naturalne. Celem pracy jest dokonanie szerokiego przeglądu istniejącego piśmiennictwa w tym zakresie. Dokonano go, korzystając z licznych, opisanych w literaturze, wyników badań wykonanych w wielu spalarniach odpadów zarówno w Europie, jak i na świecie. W analizowanych pracach poruszano tematykę zagrożeń na stanowiskach pracy, zarówno administracyjnych, jak również bezpośrednio związanych z procesem termicznego przetwarzania odpadów. Zagrożenia te wynikają między innymi z emisji do atmosfery wielu zanieczyszczeń, w tym przede wszystkim polichlorowanych dibenzo-p-dioksyn i polichlorowanych dibenzofuranów, metali ciężkich oraz niektórych lotnych związków organicznych. Wyniki badań stanowić będą istotny argument w dyskusji na ewentualnymi zagrożeniami dla ludzi i środowiska stwarzanymi przez spalarnie odpadów i celowości ich budowy w Polsce.
