Incineration Residues

Background: The use of tube-free insulin pumps is increasing. To protect the environment, the use of resources and the amount of emissions into the environment should be kept as low as possible when designing these systems. In addition to basic waste avoidance, the composition of the waste produced must be considered. Methods: To compare current tube-free pumps from an ecological standpoint, a tube-free insulin pump with a modular design and two non-modular tube-free pumps were subjected to manual separation, manual sorting, characterization, and mass determination. The annual waste volume of a user was measured, and the recyclability was assessed. The global warming potential (GWP) resulting from extraction of raw materials, energetic utilization of waste, and landfill of the incineration residues was balanced. Results: For the modular tube-free pump, a total waste volume of 5.5 kg/a (recycling percentage 44.3%) was determined. The non-modular systems generated 4.9 kg/a (recycling percentage 14.6%) and 5.1 kg/a (recycling percentage 16.0%) waste. The product-specific GWP of the modular system was approximately 50% lower than that of the non-modular systems; the packaging-specific GWP was 2.5 times higher. In total, a GWP of 13.6 kg CO2-equivalent per year could be determined for the modular system and a GWP of 15.5 kg CO2-equivalent per year for the non-modular systems. Conclusions: Although the modular micropump has a higher total waste volume, a greater ecological potential can be attributed to it. This is based on the recyclability of the system due to its modularity and the possible reduction of packaging waste.

Residual Ash

Recycling waste printed circuit boards (PCB) is an extremely complicated process, because PCBs consist of a number of complex components – hazardous and non-hazardous materials sets. Pyrolysis and combustion are currently the most effective treatment technologies for waste printed circuit boards. Pyrolysis can be used for thermally decomposing PCBs allowing for the simultaneous recovery of valuable materials. Following the extraction of valuable materials, the problem of residual ash utilization is encountered. Determining the qualitative and quantitative characteristics of incineration residue helps with choosing effective ash management technologies. This paper analyzes PCB ash generated at three different temperatures of 400 °C, 500 °C and 600 °C. Ash residues have been analysed to determine the quantity and type of metals present. Furthermore, the experiment of leaching heavy metals from ash has been described. Nebenaudojamoje elektroninėje įrangoje esančių montažinių plokščių (elektronikos plokščių) perdirbimas yra itin komplikuotas procesas, nes jos sudarytos iš daugybės kompleksinių komponentų – pavojingųjų ir nepavojingųjų medžiagų rinkinių. Pirolizė ir deginimas – šiuo metu vienos efektyviausių elektronikos plokščių apdorojimo technologijų ekonominiu ir aplinkosaugos požiūriu. Gauti elektronikos plokščių pelenai toliau naudojami vertingoms medžiagoms išgauti. Išgavus vertingas medžiagas, susiduriama su likusių pelenų naudojimo problema. Tik žinant susidariusių pelenų kokybines ir kiekybines charakteristikas galima parinkti efektyvias pelenų tvarkymo technologijas. Šiame darbe analizuojami televizorių ir kitų namų ūkių prietaisų elektronikos plokščių pelenai, kurie gauti elektronikos plokštes deginant trijose skirtingose temperatūrose: 400 °C, 500 °C ir 600 °C. Įvertinama, kiek pavojingi elektronikos plokščių pelenai. Šiame darbe taip pat atliekamas geležies, mangano, švino, chromo, vario ir cinko išplovimo iš pelenų eksperimentas, siekiant nustatyti galimą metalų išsiplovimą šalinant pelenus sąvartynuose arba jiems patekus į aplinką įvykus avarijoms.

Incineration Residues

Abstract: The presented study mainly focused on investigating detailed engineering properties of municipal solid waste incineration residues as road construction materials with different application classes. Also, the leachability of heavy metals and salts in the residues as a function of the ratio of liquid and solid was tested. The Chinese specifications about road construction materials were employed to evaluate the application capacity of the waste incineration residues. The obtained results indicate that bottom ash basically complies with the technical requirements for road base and sub-base materials with exception of the low compataclity and high organic content of the fine fraction. The toxicity test showed that bottom ash can satisfy the limit values of heavy metals and salts that was established by Chinese specification for hazard solid waste. For the application of the ash in road base, it should be mixed with other materials to improve the compataclity. Pretreatment of fine fraction of bottom ash to remove organic matter is necessary.
