Abstract:

Microemulsions were used to develop a catalyst with high selectivity towards ethylene and ethane while maintaining considerable methane (CH4) conversion. The use of this technique to produce lanthanum nanoparticles was studied under different conditions. Temperature was shown to have the most significant effect on the final material properties providing a minimum crystallite size at 25°C. The morphology observed for all the samples was flake or needle like materials containing nanocrystallites. To obtain the catalytically active materials a thermal treatment was needed and this was studied usi

Abstract:

The uptake of innovative technologies and practices in agriculture aimed at the valorisation of natural resources can be scant in Low and Middle Income Countries (LMICs). Integration of financial viability assessments with farmers and environmental evaluations can help to understand some aspects of the low uptakes of innovations. Using the case study of Cocoa Pod Husk (CPH) valorisation in Indonesia, we provide insights into (i) a choice modelling method to assess the economic viability of CPH valorisation and (ii) an agronomic trial assessing the consequences on soil quality of diverting CPH

Abstract In recent decades, from a global scale aspect, tourism demand is becoming more differentiated.

In order to compete in the world tourist market, an area must possess various and extensive resources. Therefore, new destinations that, above all, have a rich original tourist offer are required.

The utilization of lignocellulosic biomass in various applications has a promising potential as advanced technology progresses due to its renowned advantages as cheap and abundant feedstock. The main drawback in the utilization of this type of biomass is the essential requirement for the pretreatment process. The most common pretreatment process applied is chemical pretreatment. However, it is a non-eco-friendly process. Therefore, this review aims to bring into light several greener pretreatment processes as an alternative approach for the current chemical pretreatment.

Aqueous extraction of EOP under optimised conditions (10% solids, 85 ºC, and 90 min) yielded an extrac

Abstract:

The evolution of the proportion of hardwood – and especially that of beech – in Swiss forests, as evidenced by the national forest inventories in 1982–1986 and 1993–1995, is confirmed for single regions and forest enterprises. The last two forest inventories show that hardwood produced a higher increment than softwood. The average volume of each standing tree also increased. Not only will it become possible to harvest more hardwood, but the opportunity is offered to process them into end products with a higher added value. But, in fact, the harvested hardwood volumes vary widely from year to y

Abstract:

This Special Issue wants to outline the role of Geoheritage and Geotourism as potential touristic resources of a region. The term “Geoheritage” refers to a peculiar type of natural resources represented by sites of special geological significance, rarity or beauty that are representative of a region and of its geological history, events and processes. These sites are also known as “geosites” and, as well as archaeological, architectonic and historical ones, they can be considered as part of the cultural estate of a country. “Geotourism” is an emerging type of sustainable tourism, which concent

Abstract:

Intensive rearing of different animals has led to significant amounts of farming animal derived wastes, such as chicken manure, an important biodegradable waste that is still frequently applied in direct land fertilization as a method of disposal. Unfortunately, this is not a sustainable treatment option for chicken manure due to its intrinsic properties. In line with the waste management hierarchy options and with circular economy principles, chicken manure valorisation is possible after biological or chemical treatment, the first being even more desirable because it mimics the natural cycles

Growing interest in biomass valorisation in recent years has led to an increasing research focusing on its high content in phytochemicals showing high potential health benefits related to their antioxidant, anti-inflammatory and antibacterial properties, among others. On the other hand, the demand for natural antioxidants in industry is continuously increasing to avoid the harmless character of some chemical additives and, also, to limit oxidation processes in the final material, such as in food and cosmetics; increasing consumer acceptance. However, the majority of them are usually sensitive

Innovation in the circular economy (CE) and the deployment of effective circular business models (CBM) have attracted significant attention in times of growing natural resource scarcity. Despite this widespread interest, significant challenges remain between theoretical innovations and effective CBM implementation in any industrial sector where companies pursue cost-saving opportunities through waste valorisation strategies. Since current methods mislead in terms of the real limitations to designing feasible novel products and services under a circular economy, this study proposes exploring de

The sugarcane industry generates huge amounts of sugarcane bagasse ashes (SCBA). This work investigates the incorporation of a SCBA waste as an alternative raw material into a clay body, replacing natural clay material by up to 20 wt.%. Clay ceramic pieces were produced by uniaxial pressing and fired at temperatures varying from 700 to 1100 ºC. The technological properties of the clay ceramic pieces (linear shrinkage, apparent density, water absorption, and tensile strength) as function of the firing temperature and waste addition are investigated. The phase evolution during firing was followe

Phytopathogenic fungi are among the main causes of productivity losses in agriculture. To date, synthetic chemical pesticides, such as hydroxyanilides, anilinopyrimidines and azole derivatives, represent the main treatment tools for crop plant defence. However, the large and uncontrolled use of these substances has evidenced several side effects, namely the resistance to treatments, environmental damage and human health risks. The general trend is to replace chemicals with natural molecules in order to reduce these side effects. Moreover, the valorisation of agri-food industry by-products thro

Abstract:

From now on, the waste issue belongs to the problem of environmental degradation and that of the scarcity of natural resources. In this context, it’s unavoidable to move from the concept of draining waste to the one of rating them. Therefore, the waste becomes a resource.In order to take part in this new trend, since the 2000s, Algeria has engaged in a public waste management policy with different ambitious action programs. Moreover, the government has devoted institutional, financial and human means, but despite of that, the set aims are far from being achieved.This article shows us that, was
