Abstract:

Solid waste disposal, particularly of plastic and rubber, significantly impacts the environment and human health; thus, encouraging consumers to u sustainable alternatives is essential to ensure a resilient future. In recent decades, bio-based material research has primarily focused on bioplastics and, accordingly, current knowledge of alternative sustainable materials (such as biorubber) is fragmented, with consumer misconceptions posing a key challenge. This paper provides a comprehensive overview of the fundamentals of bio-based materials, in addition to common misconceptions about them. Th

<em>The Tourism’s capacity to create jobs and stimulate economic development has been especially important for rural areas, where most of the world’s poor live and where there are often few other development options. Nevertheless, as is the case for any economic sector, tourism brings certain challenges and responsibilities that must be addressed if it is to grow sustainably. As is the case for all economic sectors, if not properly planned and managed, tourism growth entails certain risks and challenges for the environment within which it operates.

Abstract:

This paper explores the viability of sustainable materials as alternatives to traditional metals like aluminium in aircraft manufacturing. Aluminium, widely used due to its lightweight and corrosion-resistant properties, poses significant environmental and structural challenges, including greenhouse gas emissions and susceptibility to thermal expansion. Composite materials, such as bio-based composites and natural-fiber reinforced composites, offer promising solutions by reducing weight, fuel consumption, and greenhouse gas emissions, while also being more cost-effective.

Abstract:

The growing urban population and increased use of healthcare services have brought significant attention to the safe and sustainable management of medical waste. Selecting the proper technology in medical waste management (MWM) represents one of the most critical challenges for decision-makers to ensure public health. In order to evaluate and choose the best MWM methodology, the current research provides a novel multi-criteria decision-making (MCDM) strategy for a variety of social stakeholders, to compute criteria weights, decision-making weights, and alternative ranking algorithms.

Abstract:

Plant-based diets have become popular as a means of reducing the environmental footprint of the diet and promoting human health and animal welfare. Although the percentages of vegetarians and vegans are low compared to omnivores, their numbers have increased significantly in the last years. The use of non-animal food products other than meat alternatives is also increasing and this tendency constitutes an opportunity for the food industry. In this review, we present that plant-based meat and milk alternatives are consolidated but that there is a niche for egg, seafood alternatives, and new pro

Abstract:

Pigment production has a substantial negative impact on the environment, since mining for natural pigments causes ecosystem degradation, while synthetic pigments, derived from petrochemicals, generate toxic by-products that accumulate and persist in aquatic systems due to their resistance to biodegradation. Despite these challenges, pigments remain essential across numerous industries, including the cosmetic, textile, food, automotive, paints and coatings, plastics, and packaging industries.

Ammonia is one of the most important industrial chemicals in the world. The availability of an inexpensive and environmentally sustainable supply of ammonia which is an important ingredient in fertilizer is important for the security of the world food supply. Asia is one of the biggest consumers of ammonia. The Haber-Bosch process makes ammonia widely available now but it requires high temperatures and pressures, consumes large quantities of fossil fuels and releases large amounts of greenhouse gases. Sustainable ammonia is also important because it may make biomass-based alternatives to fossi

Bast fibres, derived from the inner bark of plants such as jute, flax, hemp, and kenaf, play a significant role in various industries, including textiles, composites, and bioplastics. The extraction of these fibres is a crucial step that affects their quality and sustainability. However, traditional extraction methods, such as water and dew retting, while cost-effective, pose environmental challenges and yield inconsistent fibre quality. More advanced methods, including enzymatic, biological, and mechanical extractions, offer promising alternatives but come with their own set of challenges, su
