Up-Grading Biofuel Production by Co-pyrolysis of Landfill Leachate Concentrate and Sewage Sludge Mixture

Ukraine is well-known in the world as a country with soil rich for humus. Approximately 68% of arable soils in Ukraine have been classificated as chernozem. For last decades decrease of organic matter content in soils of various agri-climatic zones has been surveyed in the country. The main reason of the mentioned process is enormous lack of organic fertilizer (manure) in agriculture connected with decrease in livestock (in 3 times since year 1992). Besides there is expansion of technical crops for biofuel production (like Brassica napus, Helianthus annuus), which are the provocateurs of soils exhaustion. At the same time such important source of organic matter for application in agriculture as sewage sludge (SS) from wastewater treatment plant (WWTP) is not used in Ukraine nowadays. To stop arable soils degradation in regions it is necessary to develop up-to-date management for fertilizer production on WWTPs. The base for the process has to be the acceptance of the goal-oriented National programme, corresponding governmental decrees and implementation of national standard for using sewage sludge as fertilizer.

ABSTRACT The pursuit for waste recovery has been the best way to contribute to environmental sustainability. The mix of sewage sludge (SS) from Sewage Treatment Plant with diatomaceous material containing oil (DE), used as a filter in biofuel production, can form a substrate rich in minerals and organic matter through vermicomposting. Therefore, this study aimed to produce vermicompost using worms, Eisenia foetida, from a pre-compost (PC) of sewage sludge and garden pruning residues mixed with different proportions of DE in relation to PC: 0; 7.53; 15.06; 22.59; and 30.12% v/v. The design was randomized complete blocks with five treatment replicates. The chemical characteristics of the vermicompost were analyzed after a period of four months. The proportion of up to 30.12% v/v of DE met the criteria established for agriculture uses, registration and marketing of the product as organic compost in accordance with the Normative Instructions SDA 27/2006 and 25/2009 from the Ministry of Agriculture.

Abstract In this work, the anaerobic digestion of three microalgae (Chlorella sp., Nannochloropsis sp., and Scenedesmus sp.) and their residues, resulting from the oil extraction process and the in situ transesterification reaction for biodiesel production, using two inoculums (sewage sludge and poultry manure) for biogas production was investigated. It was found that the biogas production from digestion of oil-extracted microalgae residue with sewage sludge reached values similar to those obtained with raw microalgae (around 500 NL kg−1 VS). Both the volume of biogas generated from the microalgae residue from the extraction process of its oil and the quality of the biogas produced reflect the value of this residue to be valorized by anaerobic digestion. This approach based on a biorefinery concept and focusing on the anaerobic digestion process could be a key technology for energy production from biomass.

Both landfill leachate and sewage sludge are complex mixtures of many potentially toxic substances in unknown and unpredictable amounts and concentrations. Both types of matrices can pose a risk to human health and the functioning of ecosystems if released into the environment. Therefore, constant monitoring of the toxicity of these mixtures is necessary. However, traditional methods of analysis of sewage sludge/landfill leachate are mainly based on physicochemical studies that do not fully reflect the effects of these mixtures on living organisms. For this purpose, research based on biological models, including mammalian, mainly human, cells is recommended and increasingly implemented. A variety of cytotoxicity tests, based on various metabolic transformations in living cells, are a very useful tool in landfill leachate/sewage sludge toxicology studies. This paper reviews the methods used in the study of the cytotoxicity of environmental matrices and the cell lines used in these studies as biological models.
