... 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]. ...

... 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]. ...

... consecuente reducción en los precios de venta, lo cual a su vez afecta la economía del proceso de producción de biodiésel (Kumawat et al., 2024;Sandid et al., 2024). Con la finalidad de reducir las grandes cantidades de glicerol producidas, se han buscado alternativas para el uso de este subproducto (Tomatis et al., 2024). Entre los usos directos del glicerol crudo (de baja pureza) se incluyen su combustión directa para la generación de calor y energía; y su utilización como alimento de rumiantes debido a su aporte energético (Zacaroni et al., 2022;Zhang et al., 2022). ...

... 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). ...

... The use of conventional non-biodegradable polyesters such as polyethylene (PE) [1], polypropylene (PP) [2], polystyrene (PS) [3], and polyethylene terephthalate (PET) [4] are used worldwide for a wide variety of applications due to their low price [5], high mechanical properties [6] and good barrier [7]. Especially singleuse plastics for packaging of food [1] and pharmaceutical [8] products, etc. have become a major concern due to their impact on the environment. ...
