Tea waste was collected from a tea plant. The waste, the useless end product called sorting waste (SW), was grinded by a rod mill from original particle size of <2.36 to <1.00 mm. The SW was dried in a drying oven at 80°C for 24 h. The tea waste was used without any pre-treatments such as washing.
Biochar has been attracting increasing attention due to its ability to sequestrate carbon to improve soil quality and therefore can be beneficial for land reclamation, water remediation and soil amendment. As the energy content of biochar is higher than original biomass, it could be used as solid fuel in boilers as well. Furthermore, heavy metal sequestration is an important aspect of biochar for soil fertilisation and environmental remediation which are encountered in wastewater streams from industries. Biochar is a carbonaceous material, derived from biomass by pyrolysis. During the pyrolysis, the biomass feedstock is heated up to desired in the partial or total absence of oxygen conditions. At that point, the molecules in the biomass as organic waste reorganise to form biochar, the feed stocks carbonise and volatile molecules leave the biomass. Furthermore, carbonisation stabilise the molecules causing hysteresis behaviour when biomass is used in raw state as biosorbent.
Turning Tea Waste into biochar is much better for chaging soil quality.
Tea Waste to Biochar Production Process:
Biochar has been attracting increasing attention due to its ability to sequestrate carbon to
improve soil quality and therefore can be beneficial for land reclamation, water
remediation and soil amendment (Barrow, 2012; Meyer et al., 2011). As the energy
content of biochar is higher than original biomass, it could be used as solid fuel in boilers
as well. Furthermore, heavy metal sequestration is an important aspect of biochar for soil
fertilisation and environmental remediation which are encountered in wastewater streams
from industries.
