In this research, mangrove tree leaves and spruce cone waste residues appear from the green spaces along the road of Sagbon small village intersection, one of the busy streets in Olmozor district, Tashkent city. The collected leaves and juniper are washed with technical water to clean the upper part of the waste from harmful substances. It is also dried in the open sun for 1 day. turns into biochar in our furnace. After conversion to biochar, a simultaneous activation process with hot steam at 10 atmosphere pressure resulted in macroporous biochar. In the process of pyrolysis, mixed gases are collected drop by drop through a water cooler in the condensate method, and the obtained data are being studied. Some properties such as carbon (C), ash content (%) specific surface area and porosity, adsorption capacity were studied according to Brauner-Teller-Emmit equation. Biochar made from manju tree leaves has low carbon content and high ash content. We tested the obtained biochar in laboratory conditions
