Abstract Traditional fertilizers are highly inefficient, with a major loss of nutrients and associated pollution. Alternatively, biochar loaded phosphorous is sustainable fertilizer that improves soil structure, stores carbon in soils, provides plant the long run, yet most biochars not optimal because mechanisms ruling properties poorly known. This issue can be solved by recent developments machine learning computational chemistry. Here we review phosphorus-loaded emphasis on chemistry, learning, organic acids, drawbacks classical fertilizers, production, phosphorus loading, release. Modeling techniques allow for deciphering influence individual variables biochar, employing various supervised models tailored to different types. Computational chemistry knowledge factors control binding, e.g., type compound, constituents, mineral surfaces, binding motifs, water, solution pH, redox potential. Phosphorus release from controlled coexisting anions, adsorbent dosage, initial concentration, temperature. Pyrolysis temperatures below 600 °C enhance functional group retention, while 450 increase plant-available phosphorus. Lower pH values promote release, higher hinder it. Physical modifications, such as increasing surface area pore volume, maximize adsorption capacity biochar. Furthermore, acid affects low molecular weight acids being advantageous utilization. Lastly, biochar-based 2–4 times slower than conventional fertilizers.

Abstract The rapid growth of global industrialization and urbanization has led to the excessive use non-renewable energy sources alarming release greenhouse gases within construction industry. In response, adopting sustainable environmentally friendly building materials emerged as a vital solution for achieving international development goals set by United Nations. This review discusses potential benefits incorporating biochar-based bricks insulation materials, focusing on their preparation methods, material properties, emission reduction capabilities, effectiveness in reducing carbon emissions, enhancing thermal insulation, promising economic prospects. major points are: (1) Biochar-based offer significant footprint buildings properties. (2) With conductivity ranging from 0.08 0.2 W/(m·K), biochar contribute reduced consumption gas emissions. (3) Replacing one ton cement with brick production can substantially reduce 1351–1505 kg CO 2 -eq over entire life cycle. (4) Using part concrete saves about 59–65 dioxide per while offering clear benefits. Although is comparatively more expensive than traditional like fiberglass foam, its energy-saving advantages balance extra cost. (5) Biochar derived organic waste, contributing improved recyclability, environmental sustainability, cost-effectiveness.
