Cashew shell for CNSL

 

The global cashew nutshell liquid market was valued at USD 393 million in 2022 and is projected to reach USD 564 million by 2027, growing at 7.5% cagr from 2022 to 2027. Increasing demand from the chemical and petrochemical industries, the rising demand for natural resources for various applications are significantly driving the market globally. 

 

 

The cashew shell accounts for 70% of raw cashew nut (RCN) weight. The shell contains cashew nut shell liquid (CNSL), which accounts for 0.2 kg per kg of RCN, and the shell’s dried husk, which accounts for 0.5 kg per kg of RCN. Approximately 110K MT of shell were generated from cashew kernel processing in Africa in 2017. After extracting cashew kernels from RCN, processors typically discard the shells as a waste product. While small volumes of shells are burned to generate steam needed in kernel processing, the majority of shells (~75- 95%) are disposed of. Shells are commonly disposed of in one of two ways: shells are either dumped in designated waste sites offsite from the factory or burnt in open pits at the factory site or in neighboring areas. Both methods of shell disposal come at an economic cost to kernel processors and environmental cost to surrounding communities. In Cote d’Ivoire, kernel processors pay disposal costs of ~2K FCFA (~3 USD) per MT of shell. Moreover, once dumped, cashew shells have adverse environmental effects. As shells decompose, they release methane and carbon dioxide into the atmosphere (0.1 tCO2eq per MT of shell), and CNSL leaks out of the shells and into the ground, compromising soil fertility and polluting surface water. The alternative solution to dumping—burning the discarded shells—not only creates added energy costs for processors, but also generates carbon emissions that fuel climate change. While some processors valorize shells by extracting CNSL for sale to export markets, the remaining de-oiled shell “cakes” still pose an environmental burden. Grand Standard assist to install CNSL processing operations. CNSL is a viscous and caustic substance that can be used in the production of industrial inputs (e.g., resin, paints, varnishes, and brake fluid) as a bio-alternative to chemicals. CNSL has been shown to improve processor competitiveness, with a direct impact of ~9% on a processor’s bottom line. However, shell disposal remains an inconvenience and environmental burden: CNSL processing yields a de-oiled shell cake that must be disposed of in the same way as the raw shells. Moreover, the majority of African processors are not equipped with CNSL processing equipment, and so still face the full economic burden of shell disposal.

 

As the demand for renewable energy sources grows, businesses and individuals alike are seeking alternatives to traditional fuels that not only meet energy requirements but also align with environmental goals. We sell cashew husk pellet, a sustainable and efficient biomass fuel that is perfect for those looking to reduce their carbon footprint while maintaining high energy output.    

Grand Standard is also developing a CNSL production plant for the international market, specializing in the processing and production of cashew nut by-products. Located in the heart of a region rich in cashew cultivation, our plant is dedicated to the extraction of cashew nut shell oil, also known as cashew nut shell liquid (CNSL). This natural raw material has unique properties that make it valuable for a variety of industrial applications. Our factory project aims to maximize the use of local resources while respecting environmental standards. Using state-of-the-art technologies, we plan to optimize the CNSL extraction process, guaranteeing superior quality. Our aim is to produce pure CNSL, which can then be used in the manufacture of automotive parts, coatings and cosmetics. At the same time, we will be implementing a recycling system to reduce the waste generated by our production. Grand Standard's commitment to sustainability is reflected in our choice of materials and environmentally friendly working methods. 

Our team, with its diversified expertise, is determined to build an ethical and responsible company. We will also consider partnerships with local farmers to ensure a regular and ethical supply of cashew nuts. By aligning our business objectives with the region's economic development, we hope to contribute to improving the living conditions of the surrounding communities. With the right marketing strategy, we will position Grand Standard as a leader in the CNSL sector. This plant project represents not only a growth opportunity for our company, but also a chance to reinvigorate the local economy and promote sustainable practices. In short, Grand Standard's ambition is to become a global reference in the production of cashew nut shell liquid, while promoting social and environmental progress.
