In this study, the effects of two different forms of olive mill waste, one of the industrial agricultural wastes, on soil carbon content and some physical soil quality parameters were investigated. In this context, olive pomace and biochar which is obtained from olive mill waste were applied to...

Afforestation and reforestation (A&R) play crucial roles in mitigating land degradation and enhancing the carbon sink capacity of terrestrial ecosystems, making them integral components in addressing climate change challenges. However, the potential economic implications of A&R in the context of...

Soil organic carbon (SOC) can be increased by cultivating bioenergy crops to produce low-carbon fuels, improving soil quality and agricultural productivity. This study evaluates the incentives for farmers to sequester SOC by adopting a bioenergy crop, carinata. Two agricultural management...

The terrestrial ecosystem is the largest carbon pool in the world, and it is crucial to achieve China’s carbon neutrality goal by effectively removing carbon dioxide from the atmosphere. This study used provincial panel data from 2004 to 2020 and a spatial Durbin model to explore the...

Carbon capture and utilization technology is the research stream dedicated to mitigating the pressing effect of rising atmospheric carbon dioxide (CO2). The present study investigates a potential environmentally friendly solvent to capture and utilize CO2 using waste concrete and seawater under...

Green spaces, such as city parks, function as carbon absorption strategies for the attainment of carbon neutrality. However, urban parks are at risk of losing their carbon absorption function based on changes in carbon flux dynamics due to climate change. Therefore, this study proposes an...

Large amounts of coastal silt are converted into subgrade soil by cement solidification for resource utilization, while the compressive strength was too low (<1.0 MPa) with as little cement usage as possible (<15%, w/w). Our previous studies have shown that biochar was added into the raw materials to achieve strength enhancement, but the specific mechanisms need to be further explored. Three biochars derived from peanut shells (PSBC), cow dung (CDBC) and sewage sludge (SSBC) at 300°C, 500°C and 700°C pyrolysis, respectively were used as exogenous additives with 1%, 2% and 5%. Results showed that all biochars significantly improved the compressive strength of the subgrade soil products by 20-110%, which was attributed to that biochar catalyzed cement hydration reactions to produce more Ca(OH)2, CaCO3 and calcium silicate hydrates (C-S-H gel). The catalytic capacity of different biochars was SSBC > PSBC CDBC. Due to the suitable specific surface area and porosity of 500°C biochar, it is the most effective for strength enhancement....</1.0>

The global food crisis approach encourages finding new sources of replenishment of the phosphorus deficit in agriculture. Today, unconventional sources of phosphorus, such as sewage activated sludge from municipal wastewater, becoming particularly relevant, but despite numerous studies of...
