Overview of valorisation routes of Spent Coffee Grounds (SCG): pathway towards integrated bio-refinery & circular bioeconomy
The circular bioeconomy (CB) plan is an innovative research-based scheme intended for augmenting the complete utilization and management of bio-based resources in a sustainable route. A biorefinery can be defined as the optimised use of these bio-based resources including biomass and bio-waste for materials, chemicals, fuels and energy applications, where use relates to costs, economics, markets, yield, environment, impact, carbon balance and social aspects. Recycling of bio-waste to biofuels and value-added products through bio-refineries is a promising way to solve the problem of many countries that face daily challenges and heavy cost in waste disposal. Various kinds of bio-waste can be valorised through cutting-edge technologies for biorefineries. It is well-known that coffee is a global and popular drink with refreshing properties that is consumed in huge amounts daily. It is the second largest traded commodity after petroleum and the second most popular beverage after water. During the brewing process, millions of tons of a valuable organic waste known as Spent Coffee Grounds (SCGs) are generated representing one of the main by-products of coffee industry. SCGs stand among the most potential waste for recycling. Due to their high organic content, SCGs has been considered as a potential feedstock to develop coffee–based biorefinery through various biotechnological processes. SCGs based biorefinery is the emerging aspect promoting the global CB. The maximum energy recovery can be obtained by process integration. The sustainable CB by utilizing SCGs is achieved by the cascade approaches and the inclusion of many biorefinery approaches to obtain many bio-products. This talk aims to shadow the light into innovative processes and technologies used to recycle SCGs. Considerable developments have been reported on emerging SCGs-based processes/products in various environmental fields including production of biofuels such as biodiesel, biogas, bioethanol, bio-oil and fuel pellets besides value-added products such as bioactive compounds, nutrients, polysaccharides, bio-plastics, adsorbents, soaps & detergents, bio-polymers, nanocomposites, and compost. It is obvious that recycling of SCGs offers many worthwhile options for policy makers that can contribute towards huge financial saving on taxpayers of running and maintaining landfills besides saving the environment from harmful emissions. The economic analysis of the biofuel production from SCGs is dependent on the cost of raw material, transportation, the need of labour and energy, oil extraction operations and biofuel production. The inclusion of value-added products from already established product can minimize the investment cost when related to the production cost. A positive net present value can be achieved via SCGs biorefinery which indicates the profitability of the process. In conclusion, this talk emphasizes that SCGs-integrated biorefineries to produce different types of biofuels and value-added products are a very promising approach that shall be economically more scrutinized in the foreseen future.
