Qatar Science & Technology Park (QSTP), along with its anchor partner ExxonMobil Research Qatar (EMRQ), held a workshop to highlight research initiatives focused on the use of biochar and its potential to unlock various agricultural and environmental gains.
The workshop aimed to share EMRQ’s initiative in developing and using biochar – a carbon-rich form of charcoal that can be generated from different waste resources, such as municipal solid waste, food waste, or industrial waste – for industrial wastewater treatment, and to highlight its potential to improve soil quality and sequester carbon, explained Dr Suhur Saeed, Water Management Lead, EMRQ.
Researchers at ExxonMobil have been examining a variety of organic materials, including biochar – which, when added to soil, can improve soil productivity, encouraging plant life and crop cultivation, among other benefits – to identify ways to drive sustainability across diverse geographical and agricultural settings, for over two decades now.
Speaking at the workshop, Dr Asfaw Bekele, research advisor, Technology and Engineering, Imperial Oil, Canada, drew attention to the value of biochar in land reclamation (converting barren land into a productive state) and land remediation (removing harmful materials from the soil). “For countries like Qatar that happen to have arid, sandy soils and experience comparatively less rainfall, biochar holds tremendous potential. Especially, in relation to food security, as biochar boosts the nutrient potential of soil, providing a healthier and more nourishing home for plant growth,” Dr Bekele explained.
Another speaker at the workshop, Mohamed Gamal El-Din, professor, Department of Civil and Environmental Engineering, University of Alberta, Canada, also highlighted the significance of biochar to Qatar’s self-sufficiency efforts and shed light on biochar’s use to treat oil and gas wastewater and its contribution to supporting the circular economy – a sustainable model focused on repairing and reusing materials as long as possible to reduce the consumption of natural resources.
“Not only does biochar bring nutrients to improve soil fertility, but its physical structure increases the water holding capacity of soil. Simply put, this offers a more sustainable way of growing crops and also has a bearing on water conservation, which is another major priority area for Qatar,” he said.
The workshop also saw Dr Mohammad Alherbawi, Postdoctoral Fellow, Sustainable Development Division, Hamad Bin Khalifa University (HBKU), present an overview of the university’s research on biochar production and usage.
Researchers at HBKU have worked intensively on this aspect, Dr. Alherbawi pointed out.
According to Dr Alherbawi, the university is setting up a pyrolysis (biochar production process) pilot plant at Qatar Foundation’s Green Island, which will generate more than 100kg of biochar a day when operational. The plant will also produce fuel gas that will be used to power an on-site charging station for electric vehicles.
