“…In the study by Su, Kanchanatip, Wang, Zheng, et al (2020), food waste with varying plastic content (0%-3.5%) was gasified using SCCWG and the results showed that higher gas yield and gasification efficiencies were achieved in case of less plastic content in food waste. In another work by Su, Liao, Wang, Hantoko, et al (2020), they used a model of unsorted food waste by a mixture of food waste and plastic. Both these works clearly showed that the lower the concentration of plastic, the higher will be gasification efficiency, therefore, the sorting of food waste had positive effects on SCWG of food waste.…”

Lately, the generation of leftover food or cooked food waste has turned out to be a critical issue and its disposal in an environmental friendly way has been a challenge. This food waste is being sent for incineration and landfilling which results in a significant contribution to environmental pollution. Therefore, alternative methods for processing food waste in an environmentally benign way have been explored by many researchers. Thermochemical methods are one of those methods and are found to be promising for not only handling the food waste in an ecological way but also producing renewable energy efficiently in the form of bio-oil and syngas along with a solid byproduct, that is, biochar. However, the generation of syngas is favored by only two thermochemical processes, fast pyrolysis, and gasification. Some derived processes such as co-pyrolysis, and co-gasification can also generate syngas. All these

“…Other non-catalytic SCWG studies conducted below 600 °C (380 to 500 °C) reported low hydrogen yields (1.3 to 7.3 mol H2/kg biomass) in a batch-mode reactor with long reaction times of 10 to 120 minutes [32][49][50] [51] . However, operation at high temperatures and high pressures necessitate higher CAPEX and OPEX.…”

“…Thermal gasification is an effective method of treating and utilizing polymeric waste for energy production [ 20 ]. Although the thermochemical treatment of materials of lignocellulosic origin has been well-covered in the literature [ 21 , 22 , 23 ], the gasification of residues of polymeric origin has been presenting more relevant topics in recent research [ 24 , 25 , 26 ]. Polymeric residues have a high calorific value, and low moisture and ash content.…”

Energy Recovery from Polymeric 3D Printing Waste and Olive Pomace Mixtures via Thermal Gasification—Effect of Temperature

One of the polymeric materials used in the most common 3D printers is poly(ethylene terephthalate) glycol (PETG). It represents, in world terms, around 2.3% of polymeric raw material used in additive manufacturing. However, after processing this material, its properties change irreversibly. A significant amount of waste is produced around the world, and its disposal is usually destined for landfill or incineration, which can generate an important issue due to the high environmental risks. Polymer waste from 3D printing, hereinafter 3DPPW, has a relatively high calorific value and adequate characteristics to be valued in thermochemical processes. Gasification emerges as an innovative and alternative solution for recovering energy from 3DPPW, mixed with residues of lignocellulosic origin, and presents some environmental advantages compared to other types of thermochemical treatments, since the gasification process releases smaller amounts of NOx into the atmosphere, SOx, and CO2. In the case of the study, co-gasification of olive pomace (OLB) was carried out with small additions of 3DPPW (10% and 20%) at different temperatures. Comparing the different gasifications (100% OLB, 90% OLB + 10% 3DPPW, 80% OLB + 20% 3DPPW), the best results for the synthesis gas were obtained for the mixture of 10% 3DPPW and 90% olive pomace (OLB), having a lower calorific value of 6.16 MJ/m3, synthesis gas yield of 3.19%, and cold gas efficiency of 87.85% for a gasification temperature of 750 °C. In addition, the results demonstrate that the addition of 3DPPW improved the quality of syngas, especially between temperatures of 750 and 850 °C. Including polymeric 3D printing materials in the context of the circular economy and extending their life cycle helps to improve the efficiency of subsequent industrial processes, reducing process costs in general, thanks to the new industrial value acquired by the generated by-products.
