The aims of the study were (a) determination physicochemical characteristics properties pellets made shredded residue from hay, wheat straw, and their blend at a ratio 50:50, (b) mathematical model pellet durability, using response surface method. Tests conducted according to applicable standards. As result thermal changes during pressure agglomeration process, material moisture content had slightly decreased versus raw three biomasses by 0.50% w.b. (wet basis) final value within range...
The paper presents the development of empirical mathematical models draught force, Fx, and vertical Fy acting on duckfoots attached to tines with different stiffness working in various soil conditions. consider technical variables such as stiffness, k, tool depth-to-width ratio, d/w, movement speed, v, moisture content, MC, which have not been thoroughly analysed literature. correlation coefficients for predicting Fx values were 0.4996 0.6227, respectively. Statistical analysis confirmed...

Purpose: The paper analyses the residential construction sector in Poland, with a particular focus on single-family housing Poland regarding modular and prefabricated house market. analysis covered share of market, costs, prefabricate production processes, site work, waste management issues. Design/methodology/approach: subject observation evaluation cost level were industry reports, technology block diagrams price calculations using information provided by business entity under review....
Plastic packaging of food products has a significant impact on the sustainability industry and trade. The article presents selected problems surrounding production plastic for storage distribution that might cause disruptions in implementation sustainable production. An important question regards extent to which produces this complies with requirements. present work consists an investigation observed manufacturing company located Poland, is part global corporation. waste management was...
The paper concerns the analysis of harmful emissions during combustion process in households. subject is a low emission heating device with an output 50 kW for burning biomass forest origin (low-quality hardwoods or softwoods). proposed boiler automatically fed from connected container by means screw conveyor. In this way, optimum amount fuel supplied maximum heat (adjustment ratio primary air to fuel). system equipped and secondary supply exhaust gas sensors. This ensures optimal regulation...
The transport sector is one of the main barriers to achieving European Union’s climate protection objectives. Therefore, more and restrictive legal regulations are being introduced, setting out permissible limits for emission toxic substances emitted into atmosphere, promoted biofuels electromobility. manuscript presents a computer tool model total energy consumption carbon dioxide emissions vehicles with an internal combustion engine 2018 Toyota Camry LE. calculation designed in...
This paper analyses the influence of type electrode in a spark plug on exhaust gas emission. The objects research were following vehicles different years production: Volkswagen Beetle 1300, Honda Nighthawk 650, BMW e46 318i, Hyundai i10, and Audi A4 B6. powered by petrol LPG. Spark plugs selected for vehicles, with kinds construction main electrodes numbers poles but similar heat values. A comparative analysis composition mixture was performed, depending set used. amount CO, HC, CO2, O2...
The aim of this study was to investigate the pressure agglomeration process wheat straw (WS) and blends WS with calcium carbonate (CC) or cassava (CS) a ratio 6% wt./wt. from seven separate fractions sizes in range 0.21-2.81 mm. performed at moisture 30% wb material temperature 78 °C, dose 0.1 g, die diameter 8 mm height 80 effects were evaluated based on compaction parameters pellets' density, tensile strength, water absorption. incorporation additives into improved pellet quality. Refined...
In the dust of organic plant origin presence micro organisms, particularly moulds and endotoxins, is recorded to have harmful effects on human body cause many diseases.The microbiological quality processed plants largely dependent fragment used as raw material, since microbial contaminants are result different contacts each particular part with external environment during cultivation further processing.Organic present in material may be varied not only terms contamination, but also regarding...
