... Coffee is amongst the most widely consumed beverages around the world, with annual consumption figures reaching approximately 10 Mt [1]. Hence, the coffee industry plays a major role in the global market, offering a variety of products, including regular instant coffee, standard fresh ground coffee, coffee pods, and their decaffeinated counterparts to meet diverse consumer preferences [2]. ...

Enhancing Environmental Sustainability in the Coffee Processing Industry via Energy Recovery and Optimization: A Life Cycle Assessment Case Study

... In 2022, coffee became one of the main food products exported in the world, with a total volume of 8,466 million tonnes, which generates a value of 46,397 million USD [Laos-Espinoza et al., 2024]. This product continues to be actively popularised around the world, with North America being the leader in coffee consumption, followed by Europe, for example, the UK consumes coffee significantly less than other countries in the region, with 2.9 kg of products per capita (approximately 98 million cups per day or 175,000 tonnes per year) [Gosalvitr et al., 2024]. Approximately 650 kg of SCG is produced from 1 tonne of green coffee beans [Kim et al., 2024]. ...

... With recent expansions in global biodiesel production, there has been an excess of crude glycerol which is typically classified as waste. Consequently, various approaches for its utilization are currently under investigation [3]. Currently, 1 ton of glycerol is generated for every 10 tons of biodiesel produced. ...

... For the temperature variable, tests were carried out with a temperature range of 150-450 • C with a temperature increase of 50 • C. That is, controlled temperature tests were carried out at 150 • C, 200 • C, 250 • C, 300 • C, 350 • C, 400 • C, and 450 • C. The 50 • C increase in the temperature variable was justified because, for temperature increases below 50 • C, the differences between the results were not sufficiently significant. These test temperature values were within the pyrolysis temperature ranges [31]. If the carbonisation process was carried out at low temperatures (~200 • C), the charcoal yield was higher than the dry mass in the kiln. ...

... This is expected because Malaysia produces a vast amount of solid wastes. For instance, each hectare of palm oil produced alone emits about 50-70 tons of biomass waste (Saharudin et al. 2023). Lignocellulosic biomasses generated from these agricultural wastes from oil palm plantations include oil palm shells, coconut shells, palm kernel shells, and empty fruit bunch shells (Oyekanmi et al. 2021). ...

... Poly(mandelic acid) (PMA) represents a biodegradable polymer that shares structural and property similarities with polystyrene (PS) but offers the additional benet of environmental sustainability. [1][2][3] Traditionally, PMA synthesis via bulk ringopening polymerization of mandelide lacked control over its molecular weight and distribution. High-temperature ROP led to stereocenter epimerization and racemization. ...

... One key issue with the latter two approaches (i.e., blends and composites) is the recyclability of the recycled products. Composite materials and polymer blends often exhibit higher degrees of complications in recycling due to more complicated chemistry and composition and difficult separation of constituents (Tomatis et al., 2023). Depending on the blend and its characteristics, specialized processes may be necessary for their effective recycling (Dorigato, 2021). ...
