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.

<em>The Tourism&rsquo;s capacity to create jobs and stimulate economic development has been especially important for rural areas, where most of the world&rsquo;s poor live and where there are often few other development options.

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:
&lt;p&gt;The increasing focus on sustainability and reducing greenhouse gas emissions presents significant challenges for the flat glass industry. Consequently, research into more sustainable solutions for structural glass construction has markedly increased in recent years. This paper provides an over- view of the current advancements in low-emission technologies within this sector. Thereafter, it examines the potentials and challenges associated with laminated safety glass (LSG) in detail. It is shown that by using liquid cold-poured interlayer adhesives (LCPI), there is significant potentia

Abstract:
The global food system faces environmental, social and legal challenges. Primary production has become increasingly dependent on external inputs from industrial companies, which contribute to the rising cost of nutritious food and decreasing the income of producers, particularly the producers in primary production. Adopting alternative models of short food supply chains can reduces those negative effects and moves the agri-food supply chain towards some Agenda 2030 sustainable developments goals and aims of European Strategies in the agrifood field.

Abstract:
Cabbage (Brassica oleracea var. capitata) is a vital crop for Kenyan smallholder farmers, contributing to food security and income. However, declining soil fertility and reliance on costly synthetic fertilizers pose significant challenges. This study aimed to evaluate the efficacy of OBLIGA BONACRAFT P20S10, a microbiological phosphorus-sulfur fertilizer, as a sustainable alternative. Field trials were conducted in four agroecological zones: Kiambu, Kirinyaga, Machakos, and Murang'a, using a randomized complete block design (RCBD) with three replications per site.

The global reliance on fossil-based solvents has driven the search for sustainable alternatives. This study employs the IBSS� CAMD tool to evaluate building blocks derived, directly or indirectly, from agricultural residues - specifically orange and coffee wastes-, to replace toluene in furfural extraction. A three-stage methodology was implemented: (1) identification of potential building blocks from residues, (2) multi-objective optimization using genetic algorithms and group contribution models for properties calculation, and (3) analysis of the resulting candidates based on performance ind

Renewable carbon sources, such as biomass and waste, are being explored as alternatives for sustainable plastic production. However, the significant uncertainties surrounding the environmental impact of biomass supply processes raise questions about whether these plastics positively contribute to society. Furthermore, the lack of systematic knowledge about plastics and incomplete understanding among stakeholders pose challenges to conducting comprehensive assessments and designing effective plastic life cycle systems.

Many countries in the global South declare regions to be open defecation free (ODF), but they must still address significant sanitation, wastewater, and faecal sludge management challenges. Climate uncertainty, water shortages, and weak infrastructure mean that ‘flush and forget’ systems are not always possible or desirable. This briefing describes how art interventions can help people reimagine alternative sanitation futures.
