“By controlling the temperature during the pyrolysis process [when the waste is being burned], we get a good charcoal that is adapted to the soil of Morocco — we cannot import a product like this,” El Hemer explains.
Biochar is becoming an increasingly popular solution worldwide. The International Biochar Initiative estimates the market will grow at a rate of 14.5% until 2025. It says the increased need for organic soil enhancement, government rules over the preservation of soil, the growing biofuel sector, and other factors will contribute to this growth.
Composting not an option:
Reclaiming organic waste as compost is not an option for Agadir’s farmers. Agricultural techniques are to blame: as tomato plants grow taller and taller in the greenhouses, farmers fasten the vines to plastic sticks using plastic ties. “After that, you can’t separate the plastic from the plant, so it’s difficult to compost,” El Hemer says. “There is also bacteria in the plant that causes a big problem when composting.”
To transform this pile of organic leftovers and plastic into something usable, El Hemer invented a mechanical chopper that shreds the greenhouse waste. “It’s quick, and the job is done in one day,” explains El Hemer, adding that the fee he charges farmers is less than the cost of clearing the greenhouse and burning what remains. Once shredded, El Hemer takes the waste to a site near his family home where it is heated and transformed into biochar.
Bringing biochar to the market:
Until the PEPS partnership comes through, El Hemer admits he is still at the beginning of his entrepreneurship journey. He currently collects waste from two small-scale farmers, and has already been in talks with bigger agricultural players, ones with more than 200 hectares (two square kilometers) of greenhouses. With social responsibility and environmental mandates, and the ongoing desire to reduce the cost of biomass disposal, El Hemer says big companies are the ideal customer.
Producing more biochar fertilizer will also depend on building more mechanical choppers, and constructing a green kiln where the biochar can be carbonized. He is particularly interested in building a kiln that would collect the smoke used in the waste pyrolysis process. By doing so, El Hemer says the smoke could be reused in the combustion chamber, thereby recycling the emissions it takes to create biochar. El Hemer expects the kiln to be built by the end of the year, around which time he also plans to formally register the business as a start-up.
An upcoming partnership could be a way to improve this technique: El Hemer has been in talks with PEPS, a Moroccan-French company based in Marrakech that uses solar energy to power the pyrolysis process. By using the sun to heat the 600° reactor chamber, PEPS’ process is entirely green and can transform biomass into biochar at a much higher rate.
“El Hemer knows the system of artisanal pyrolysis very well, and he knows all about the finished product and the local market,” says Hamza El Baroudi, the CEO of PEPS. “He has an interesting view of the potential of the Agadir market, and we want to learn more from him. In turn, we will come with the technology to transform the biggest amount of waste possible — up to 800 tons a year.”
Just as he promoted his green charcoal briquettes and biochar during COP22, El Hemer is hustling his biochar fertilizer now. With little market competition, high demand, and promising partnerships on the horizon, El Hemer says he thinks 2018 will be his best year yet.
