Carbonization of waste PVC to develop porous carbon material without further activation

Waste Management, 2006
Efficient removal of chlorine from PVC achieved by two-stage heat-treatment (280 and 410 degrees C) provided chlorine-free isotropic pitch containing additive. The pitch was stabilized and carbonized into porous carbons with surface areas of approximately 300 m2/g.

Hydrogenation of carbon dioxide: From waste to value

Current Opinion in Green and Sustainable Chemistry, 2020
Abstract Atmospheric carbon dioxide concentration has been increasing in the last two decades and, as a major greenhouse gas, it has been linked to global warming and climate changes. Capture and conversion of CO2 into fuels and chemicals offers opportunities to mitigate the increasing CO2 buildup, while simultaneously adding value to CO2.

Impact of waste processing byproducts on the carbon footprint of integrated waste-to-energy strategies

Journal of Environmental Management, 2021
Resource recovery is a promising solution for multiple waste and economic challenges worldwide. Although the life cycle environmental performance of resource recovery systems has been widely studied, the impacts of their resultant waste processing byproducts remain unassessed.

Activated carbon production: Recycling KOH to minimize waste

Materials Letters, 2018
Abstract Synthesis of activated carbon by chemical activation results in materials with high surfaces areas and pore volumes (e.g., >1800 m2/g and >1 cm3/g). The main problems are the large amount of chemical required and the waste water created.

Synthesis of Carbon Dots from Kitchen Waste: Conversion of Waste to Value Added Product

Journal of Fluorescence, 2014
Synthesis of Carbon dots (C-dots) from bio-degradable waste is a much researched subject now-a-days. The demand for green chemistry and cost-effectiveness lead us to synthesize C-dots from kitchen waste. Nanometer sized carbon particles with unique optical properties were observed during the study. A simplistic approach was used for the synthesis which

Waste-derived carbon nanostructures (WD-CNs): An innovative step toward waste to treasury

Environmental Research
With the growing population, the accumulation of waste materials (WMs) (industrial/household waste) in the environment incessantly increases, affecting human health. Additionally, it affects the climate and ecosystem of terrestrial and water habitats, thereby needing effective management technology to control environmental pollution.

Thermal conversion of municipal solid waste via hydrothermal carbonization: Comparison of carbonization products to products from current waste management techniques

Waste Management, 2012
Hydrothermal carbonization (HTC) is a novel thermal conversion process that may be a viable means for managing solid waste streams while minimizing greenhouse gas production and producing residual material with intrinsic value. HTC is a wet, relatively low temperature (180-350 °C) thermal conversion process that has been shown to convert biomass to a ...

Waste to biofuel through hydrothermal carbonization

2014
In this paper, the potentialities for energy purposes of “off-specification compost” (EWC 19.05.03) are studied. This is a residual byproduct from the treatment of the organic fraction of the municipal solid wastes that is not usable as soil improver according to the current Italian law.
