Kemin Industries, together with its partners Adesco Nutricines and Dow, a global leader in materials science, has performed a life cycle assessment of Kemin's Myco CURB® ES Liquid on stored grains, demonstrating that treatment with this solution is more environmentally sustainable than drying or aerating stored grains.

The company's Animal Nutrition and Health – EMENA (Europe, Middle East, North Africa) business used the United Nations' Sustainable Development Goals to help determine its focus areas and responsibilities. Kemin guides its sustainable action using a triple-bottom-line approach that encompasses three overlapping areas: Healthy People, Healthy Planet and Healthy Business.

"These three lenses provide the framework we use to measure the impact of our efforts. Each lens includes both an internal and external scope," said Stefaan Van Dyck, president of Kemin Animal Nutrition and Health – EMENA. "The internal scope addresses, for example, how we can improve our internal operations, sourcing and production processes. The external scope looks at how our solutions (products and services) can sustainably transform lives, animal welfare, the environment and our customers' operations, to name a few."

One of Kemin's suppliers, Dow, has set its own ambitious Sustainability Goals for 2025. Dow is working with like-minded partners to help lead the transition to a more sustainable planet and society. "As we advance our third set of 10-year sustainability goals, our sustainability journey has evolved from focusing on operational efficiency (our footprint), to product solutions and world challenges (our handprint), to recognising that only through collaboration can we accelerate our positive impact (blueprint thinking)," said Andrea Blanco Acuña, marketing manager of Dow's Feed & Food industries – EMEAI.

A crucial step for Kemin, Adesco and Dow is carbon footprint analysis of stored grains preserved with Kemin's Myco CURB ES Liquid, compared to other grain storage methods.

Life cycle impact assessment should be viewed as a holistic approach in which solutions contribute to sustainability by reducing the CO2 equivalents (CO2-eq) per kilogramme of food and improving animal productivity, welfare and profitability, Kemin said.

"Life cycle impact assessments must look at the complete value chain, from raw materials to the end-product contributing to a "healthy business". At Kemin, we want the impact of our solutions to enhance the marketability of food produced, and we cannot do this exercise without our suppliers," said Van Dyck.

"This project is an example of Adesco's commitment to helping the industry adopt commercially insightful practices that enable carbon reduction across the feed and food chain," said Jack O'Hare, managing director of Adesco. "Good data drives good decisions, and by providing customers with accurate and externally validated information, we can help accelerate adoption of solutions that make a sustainable difference."

"Transitioning to a sustainable future is a business imperative for Dow. As a materials science company, we play an important role in providing scientific expertise and encouraging the incorporation of sustainability principles in our customers' business plans," said Blanco Acuña.

Kemin, Dow and Adesco jointly conducted a gate-to-gate life cycle assessment study to investigate the greenhouse gas emissions in CO2-eq of barley and wheat using three different methods of grain storage: aeration, drying and preservative addition. The study, which began in July 2019, was conducted based on data compiled by Adesco in Ireland during harvest. The extended storage period is applicable to typical Atlantic climate conditions (West North Europe) with a high average rainfall throughout the year and wetter harvests.

"The results from this study demonstrate that drying and aerating grain create a bigger carbon footprint than treating grains with Myco CURB ES Liquid," said Carmen Coetzee, product manager of Kemin Animal Nutrition and Health – EMENA. "The addition of a mould inhibitor – a preservative based on propionic acid and a synergistic combination of other organic acids, their salts and surfactants – enables a reduction of approximately two to three times the carbon footprint in kilogramme CO2-eq per tonne of grain stored, compared to aeration and drying methods, respectively. This information is critical to our customers, who can immediately use these insights to optimise their sustainability impact. For Kemin, this study and its results are a decisive step in defining the life cycle impact assessment of our entire value chain."

For all the partners involved in this life cycle assessment, external validation was crucial to the study. Blonk Consultants granted certification attesting that the life cycle assessment of this study, in which Myco CURB ES Liquid was used to treat stored grain, meeting the requirements of ISO 14040 and 14044.

"The results of this groundbreaking life cycle assessment demonstrate that treatment of grain with Myco CURB ES liquid offers the industry an immediate, significant and practical means to reduce the carbon footprint of grain processing and feed production," said Sean O'Hare, engineering and sustainability manager of Adesco. "Our customers are reassured by recent animal performance studies indicating that using treated grain in their feeds enables them to cut their carbon emissions without loss of feed efficiency or reduced animal performance."

The joint study carries importance for the food and feed industry.

"Together, we could quantify the positive impact of a technical solution in terms of environmental metrics, and this encourages us to keep using data and science in our activities across the value chain," said Inge Hageman, global account manager of Dow.
