Opis:: The paper reports on wastewater management in food processing enterprises, using the Ciechanów Dairy Cooperative as an example. The efficiency of preliminary treatment of wastewater entering the municipal sewerage system was evaluated using basic pollution indices for wastewater pre-treated in the process of chemical neutralisation as well as results of physical and chemical analyses of raw wastewater from fromage fraise and cottage cheese production lines. The number of exceedances of permissible values of pollution indices in pre-treated wastewater was determined based on values set in the water legal permits issued by the relevant authority. Pretreated wastewater entering the municipal sewerage system met the standards for permissible wastewater pollution indicators excluding BOD₅ (biochemical oxygen demand) and COD (chemical oxygen demand). Physical and chemical analysis was performed of total raw wastewater and wastewater discharged from fromage fraise and cottage cheese production lines. Pollution indicators (COD, total nitrogen, orthophosphates, total suspensions, fats, pH) had high values but they remained within the ranges typical for dairy food processing.

Opis:: In order to increase the efficiency of implementing the emergency response measures, the emergency response plan drawing up, revision and implementation at oil production enterprises, it is expedient to use an analogue of the supervisory control and data acquisition (SCADA) system, which generates an interactive mode that allows interaction with the person in charge for localizing and eliminating the consequences of accidents that negatively affect, inter alia, the environmental situation. The SCADA system was developed on the basis of the approved document "Emergency Response Plan" and provides for data exchange with the automated systems of the enterprise to form a complete description of the situation for the person in charge for localizing and eliminating the consequences of accidents. The automated system application software was developed using high-level programming languages (Embarcadero Delphi or analogues) and technologies for direct access to the Oracle database management system. The use of an automated system is feasible for large enterprises of the extractive and processing industries with the possibility of integration into the automated Manufacturing Execution System (MES-systems) of an enterprise.

Tytuł:: Analysis of the Energetic Use of Fuel Fractions Made of Plastic Waste

Opis:: The overriding principle of waste management (already produced) is their reuse or use as secondary materials. It is consistent with the concept of a circular economy. Recycling materials and raw materials have the highest rank in the field of waste processing. For non-recyclable waste, other recovery processes also play a role. In the case of plastic waste, economically and ecologically justified processes of thermal transformation and catalytic depolymerisation leading to the formation of fuel fractions destined for energetic use may be useful. This direction of polymer waste processing is justified by the high calorific value of plastics. In the objective evaluation of waste treatment technologies, from the point of view of economics and environmental protection, it may be helpful to analyse the energy balance. The aim of the article is to analyse and evaluate the energy efficiency of using a mixture of hydrocarbons obtained in the process of catalytic depolymerisation of plastic waste based on the energy efficiency index for energy purposes. The efficiency index is calculated as the quotient of energy benefits and energy inputs for the use of depolymerisation products. Energy expenditure includes expenditures incurred in individual stages of the life cycle of a liquid product made of plastic waste. The conducted analysis showed that the energy use in the post-use phase of polymer products allows for the recovery of nearly 40% of the energy required for the production of products and processes enabling the use of waste from these products. Despite the low efficiency index, energy recovery from non-recyclable plastic waste should be considered as a positive action. Plastic packaging waste subjected to catalytic cracking can be included in the settlement of the obligation to achieve the required level of recovery if the cracking products are used for energy purposes.
