Biochar Use Cases: The Middle East

Biochar, a charcoal-like substance derived from organic materials, holds immense potential for sustainable agriculture, environmental management, and industrial applications. In the Middle East, where arid climates and soil degradation pose significant challenges, biochar offers promising solutions across various sectors.

Use Case #1: Enhancing Soil Fertility (Saudi Arabia)

Use Case #2: CO2 Capture and Sequestration (UAE)

Use Case #3: Water Filtration and Desalination (Nigeria)

Use Case #4: Water Purification (The Philippines)

Use Case #1: Enhancing Soil Fertility (Saudi Arabia)

In the Middle East, where fertile, arable land is in short supply, heavy metal-contaminated soils pose a severe threat to the ecosystem, especially since there is limited area available for safe food production. Human activities like mining are the region’s primary source of heavy metal pollution, but nowhere is this more evident than in the Kingdom of Saudi Arabia. To rehabilitate and maintain the viability of land used for crops, it is crucial to limit the accessibility of heavy metals to plants in contaminated soils.

Soil Remediation:Biochar Provides A New Solution For Metal Contamination

In a 2014 study, biochar (produced from pyrolysis of Conocarpus-buttonwood) was added to metal-contaminated soil from the mining area of Mahad Ad’ Dahab, Saudi Arabia, to measure its effects on moisture content, heavy metal concentrations, and soil quality for growing maize plants.

Results showed that biochar improves soil moisture content by 30% at a 75% moisture level and doubled the retained moisture at a 100% moisture level. Biochar reduced bulk density by 12%, improving soil quality. Since high bulk density can halt microbe activity and other biochemical processes needed for plant growth. The incorporation of biochar also significantly reduced the content of heavy metals, with the highest reduction of 51.3% and 60.5% for manganese, 28.0% and 21.2% for zinc, 60.0% and 29.5% for copper, and 53.2% and 47.2% for cadmium at soil moisture levels of 75% and 100% FC, respectively.


Key Points 

  • Biochar improved the soil moisture content of maize plants grown in metal-contaminated soil by 30% at a 75% moisture level and doubled the retained moisture at a 100% moisture level.
  • Biochar reduced soil bulk density by 12%, improving soil quality and plant yield.
  • Most importantly, biochar significantly reduced the plant uptake of heavy metals, with the highest reduction of 51.3% and 60.5% for manganese, 28.0% and 21.2% for zinc, 60.0% and 29.5% for copper, and 53.2% and 47.2% for cadmium at soil moisture levels of 75% and 100% FC, respectively.

Use Case #2: CO2 Capture and Sequestration (UAE)

Biochar offers an innovative solution to both waste management and carbon capture, specifically in the United Arab Emirates and in the greater region. Date palm leaf bio-waste, a different form from the traditional feedstocks usually made into biochar, was studied for its carbon sequestration and C02 capture capacity.

Date Palm Biochar: A Regional Alternative Performs Well Under Pressure

In a study of date palm biochar as a climate change solution, the pyrolysis (heating the biowaste in the absence of oxygen) of the date palm leaf was performed at different temperatures ranging from 300°- 600 °C, with the DPL biochar produced retaining between 7% to 25% of its weight in C02. The biochar’s C02 absorption capacity increased with the temperatures used for the pyrolysis process.

Studies by Sizirici et al. (2021) concurrently revealed that the carbon content of the date leaf biochar was amplified with an increase in the pyrolysis temperature: The carbon content of feedstock was 31 percent, which increased to 47–57 percent in leaf biomass samples.

Date palm leaf biochar production is a sustainable agricultural practice that contributes to waste management and soil enhancement, as date palm leaf bio-waste is common in the Middle Eastern region, with very few helpful disposal alternatives. It can create economic opportunities for farmers and communities by adding value to agricultural residues and developing markets for biochar products.


Key Points 

  • Date Palm Leaf biochar retained between 7% and 25% of its weight in C02.
  • The biochar’s C02 absorption capacity increased with the temperatures used for the pyrolysis process.

Use Case #3: Water Filtration and Desalination (Nigeria)

Studies have shown that biochar can effectively remove contaminants and impurities from water, making it suitable for irrigation and human consumption. It is particularly relevant in water-scarce areas throughout Africa and the Middle East.

Sustainable Treatment of Wastewater with Biochar and Bio-Sand Filtration

A joint experiment between the Federal College of Petroleum Resources in Effurun, Nigeria and Tennessee Technological University in the US, examining the efficiency of biofilters consisting of gravel, cassava-peel biochar and sand to filter oily wastewater, has produced some remarkable results.

The constructed biochar-based filters indicated that the oily wastewater, after being treated by the biofilter, had a percentage reduction of 56.89% – 83.44% in organic pollutants and reduced chemical contaminants by 32.67%.

The filtration system was also tested for heavy metal filtration, with the results underscoring the potential of cassava peel biochar to effectively mitigate specific heavy metal concentrations, like lead, nickel, copper, iron and zinc.

In the study, lead was reduced by up to 74% nickel and 54%, with copper and chromium being wholly removed from the treated water samples, revealing the cassava peel biochar’s exceptional efficiency in eliminating those two minerals. Iron was reduced by approximately 25%, while zinc was reduced by 50%.

Key Points 

  • Water treated by the biochar/bio-sand filter system had a percentage reduction of 56.89% – 83.44% in organic pollutants and reduced chemical contaminants by 32.67%
  • The cassava-peel biochar-based filter reduced the lead by up to 74%, nickel by 54%, iron by approximately 25%, and zinc by 50%.
  • During biofiltration, copper and chromium were removed entirely from the treated water samples, demonstrating 100% filtration efficiency for those two particular metals.

This biochar application can offer a sustainable solution for resource conservation and land restoration due to the effects of petroleum extraction and refining, which are significant industries throughout Africa and the Middle East.

Use Case #4: Biochar as a Renewable Energy Source )

With the current energy crisis and depletion of fossil fuels, finding sustainable and eco-friendly energy sources is crucial, and there are several biomass conversion pathways for producing bioenergy as a valuable byproduct of making biochar, with the ability to create electricity, biodiesel, and biohydrogen.

Not Just for Agriculture – Biochar Creates Its Own Clean Energy

Biochar from biomass can yield high biodiesel during conversion, ranging from 32.8% to 97.75%.

It can also serve as an anode, cathode, and catalyst in microbial fuel cells with a maximum power density of 4346 mW/m2. Biochar also plays a role in catalytic methane decomposition and dry methane reforming, with hydrogen conversion rates ranging from 13.4% to 95.7%. Biochar can also increase hydrogen yield by up to 220.3%.

In general, biofuels produced from biomass, including biochar pyrolysis, can displace up to 27% of the world’s transportation fuel by 2050, reducing greenhouse gas emissions by up to 3.7 billion metric tons per year.


Key Points 

  • Biochar can yield high biodiesel during conversion, ranging from 32.8% to 97.75%.
  • It can also serve as an anode, cathode, and catalyst in microbial fuel cells with a maximum power density of 4346 mW/m2.
  • Biochar also plays a role in catalytic methane decomposition and dry methane reforming, with hydrogen conversion rates ranging from 13.4% to 95.7% and increasing hydrogen yield by up to 220.3%.
  • Biofuel production (including biochar energy sources) could reduce greenhouse gas emissions by up to 27%, or 3.7 billion metric tons per year.

Biochar Use Cases: Asia

Use Case #2: Pine Tree Reforestation and Inoculation (Japan)

Use Case #4: Water Purification (The Philippines)

Use Case #1: Greenhouse Gas Reduction/ Carbon-Neutral Agriculture (China)

Biochar, a promising solution, can reduce greenhouse gas and increase organic carbon in soil. Recent groundbreaking research from the Center for Landscape Research in Sustainable Agricultural Futures at Aarhus University has unveiled a biomass pyrolysis (biochar) system. This innovative system involves heating biomass, such as straw, without oxygen to produce biochar. The implications are significant: biochar could slash greenhouse gas emissions from Chinese crops and generate biogas and bio-oil as valuable byproducts for electricity production.

An Integrated System to Combat Climate Change

 Applying biochar in rice fields as part of an integrated system offers practical benefits. With its slow decomposition rate, biochar effectively sequesters carbon in the soil for a more extended period. This, along with the displacement of fossil fuels by bio-energy, forms the primary means of reducing emissions. The data suggests this biomass energy system could reduce greenhouse gas emissions from 666.5 Tg to -37.9 Tg CO2-equivalent yr. This integrated system can also increase rice crop yield by 8.3%, significantly boosting agricultural productivity.

 By embracing this innovative solution, China can achieve its carbon-neutral goals and pave the way for sustainable agriculture. The practical benefits are clear: reduced greenhouse gas emissions, increased crop yield, and the potential for bio-energy production, which creates a win-win situation for both the environment and the agricultural sector.

Key Points 

  • Data suggests a widely adopted biomass energy system could reduce greenhouse gas emissions from 666.5 Teragrams (Tg) to -37.9 Tg CO2-equivalent per year. 1 Teragram is 1,000,000 metric tons.
  • The proposed biomass system would also positively affect rice crop yield by approximately 8.3%

Use Case #2: Pine Tree Reforestation and Inoculation (Japan)

This use case involves using biochar powder to help cultivate the edible and dominant mycorrhizal fungus Rhizopogon rubescens associated with pine trees like Pinus thunbergii to promote their growth and inoculation. When small amounts of fertilizer were mixed with bark charcoal powder, and the mixture was applied to pines, fresh roots regenerated inside the charcoal layers three months later.

Regrowing Roots

 After a year of implementing the biochar system, the results were impressive. The amount of pine root and mycorrhiza in the charcoal increased significantly, improving the growth and colour of pine shoots. These seedlings’ survival rates and growth were consistently higher than those without mycorrhiza and charcoal. This is believed to be due to the enhanced uptake of nutrients and water absorption from increased mycorrhizal formation. The water content of the pine roots in the biochar was also considerably higher (40%) than that of a control group placed in sand (5%), simulating the dry season (Ogawa 1992).

Key Points 

  • The growth and colour of pine shoots and the amount of pine root and mycorrhiza in the presence of biochar considerably improved during biochar treatment.
  • The water content of the pine roots in the biochar was considerably higher (40%) than that of a control group simulating the dry season.

Use Case #3: Biochar Used as Vapor-absorbent Materials for Construction Materials and Explosives (South Korea)

South Korean commercial wood chip (WC) and biosolid (BS) biochars were used to make biochar-mortar composites tested for their carbon sequestration and absorption capacity. The biochar-mortar composites retained their engineering properties, including flowability, compressive strength, and thermal conductivity, with 3-5 wt.% biochar.

Clearing the Air

 As the biochar content increased, the concentration of benzene and toluene in the air decreased, indicating that biochar inclusion can remove volatile toxic contaminants that cause sick building syndrome. Bioassay tests confirmed that the biochar-mortar composites were not harmful, suggesting they could be environmentally friendly carbon-sequestering construction materials. The biochar composites were also evaluated to be useful as a sorbent (vapor-absorbing material) for nitro explosives, blocking a proportionate amount of nitroglycerin fumes from being inhaled by workers, a necessary safety component for many commercial explosives.

Key Points 

  • Adding 3-5% biochar to biochar-mortar composites reduced benzene and toluene concentrations in the air, preventing Sick Building Syndrome from phenol-based construction materials.
  • Biochar composites effectively block a proportionate amount of nitroglycerin fumes from entering the air, making them a valuable sorbent for worker safety in commercial explosives.

Use Case #4: Water Purification (The Philippines)

The CRZ or Clean River Zones project is a partnership between the Philippine Biochar Association, Philippine Mining Safety and Environment Association, and GMA7, a central television station in Manila, and aims to clean up Diliman Creek, located in Quezon City, Philippines, using Bokashi Balls.
Bokashi Balls, initially developed in Japan, contain a mixture of rice-hull biochar, soil and molasses, with the soil and biochar containing lactobacillus bacteria and other microorganisms that cleanse pollutants, eliminate foul odours and reoxygenate small bodies of water.

Clean River Zones – The Differences Are Visibly Clearer

 Another similar project was launched at Maningning Creek in Santa Ana, where upstream factories had turned the creekwater black and caused several severe outbreaks of dengue fever. In both Diliman and Maningning, the result has been visibly clear water, elimination of the creek’s once-noticeable odour and a more solid river floor, plus the absence of any further dengue outbreaks in Santa Ana in particular. Diliman and Maningning serve as a model for rehabilitating waterways, an example to be replicated to save other creeks and rivers in other ASEAN countries.

In another concurrent study conducted at the Turawa reservoir (Poland), evaluating effective microorganisms in the form of Bokashi balls, the analysis showed that it could be one of the most effective methods for cleaning water from unfavorable microorganisms (HBN22, HBN36, CBN, FCBN, FEN). After applying the Bokashi balls, their average concentration was reduced (from 46.44 to 58.38%). The duration of their effect ranged from 17.6 to 34.1 days. Using other water purification methods alongside the bokashi balls, like constructing wetlands, floating beds, or intermittent aeration, only increased the purification effect and improved the trophic status of the Turawa reservoir, expressed by the Carlson index, by 7.78% overall.

Key Points 

  • Bokashi Balls, containing a mixture of rice-hull biochar, soil and molasses, along with lactobacillus bacteria and other beneficial microorganisms, have been shown to cleanse river pollutants, eliminate foul odors and reoxygenate small bodies of water, returning river water that was visibly black back to clear.
  • Analysis showed that after applying the Bokashi balls, the concentration of harmful organisms in river water was reduced by 46.44 to 58.38% on average.
  • The duration of their effects ranged from 17.6 to 34.1 days but was prolonged when used with other purification methods like constructing wetlands, floating beds, and intermittent aeration.
