For many mills, the biosludge from wastewater treatment is difficult to recycle or dispose of. This makes it a challenging side stream and an important issue for chemical pulping. It often ends up being burned in recovery biomass boiler, although moisture non-process element (NPE) contents make problematic fuel. Biosludge has proven resistant attempts reduce its moisture. When incinerated heat ...

In today’s world, due to population increase, there are many alarming and potential catastrophic problems like climate change, environmental pollution an enormous mass of wastes constantly produced by humankind find innovative solutions for the management, recycling, valorization biowaste from agricultural production, food processing, organic household residues. The search sustainable efficient...

Hydrothermal carbonization (HTC) can process anaerobic digestion effluent (ADE) from sewage sludge into hydrochar and liquor. The objective of this study was to assess the effects HTC temperature, time, initial ADE pH on yields properties conducted at different (original ~8.2 modified ~6.8), temperatures (180 260 °C) times (30 70 min) following a central composite design. Hydrochar original ran...

Hydrothermal carbonization (HTC) is a novel thermochemical conversion process to convert lignocellulosic biomass into value-added products. In this work, two different biomass materials: corn stalk and Tamarix ramosissima were used as feedstock. HTC processes were performed at the temperature of 250 °C for 4 h, using a batch reactor system. Chemical and structural characterization of the solid ...
