“…The mixture of wastes proposed in this paper, in terms of biogas yield, is an alternative to the use of energy crops such as reed canary grass, miscanthus, and Virginia mallow. Moreover, a good yield of energy crops can only be obtained on fertile soils, which de facto should be used for food production (Giovannetti and Ticci 2016).…”

A multi-enzymatic biopreparation of Trichoderma atroviride G79/11 origin was characterized. The fungus showed relatively high cellulase production in a soybean flour-cellulose-lactose medium. Subsequently, based on its post-culture liquid, the biopreparation of the enzyme mixture was developed and characterized. The liquid form of the enzyme mixture reached 22 U cm -3 of cellulolytic activity and its lyophilisate exhibited 1.09 U cm -3 at pH 5.1 and 50 °C. The enzyme mixture was characterized by the following activities: xylanase, β-glucosidase, carboxymethyl cellulase, polygalactouronase, pectinesterase, amylase, lactase, and protease. A method for an efficient conditioning process of organic waste (fruit processing waste, dairy sewage sludge, corn silage, and grain broth) for biogas yield enhancement using the enzyme mixture was proposed. The enzyme mixture increased the efficacy of biogas production by 30% when the lyophilizate (0.5 mg g -1 d.m.) was applied prior to fermentation. A method for conducting the enzymatic conditioning process of organic waste using the enzyme mixture as a pretreatment was proposed. This was part of the optimization of the methane fermentation process to increase the biogas yield. Consequently, after application of the biopreparation, the efficiency of anaerobic digestion of organic waste was improved.

“…(Scoones et al 2013b, Rulli andOdorico 2013). Indeed, several examples exist where the Land Matrix and other similar data have been successfully used to assess LSLA in a number of contexts(Deininger and Byerlee 2011, Rulli et al 2012, Anseeuw et al 2012, Giovannetti and Ticci 2016, Breu et al 2016.…”

Large scale land acquisitions (LSLA), and Reducing Emissions from Deforestation and forest Degradation (REDDþ) are both land based phenomena which when occurring in the same area, can compete with each other for land. A quantitative analysis of country characteristics revealed that land available for agriculture, accessibility, and political stability are key explanatory factors for a country being targeted for LSLA. Surprisingly LSLA occur in countries with lower accessibility. Countries with good land availability, poor accessibility and political stability may become future targets if they do not already have LSLA. Countries which high levels of agriculture-driven deforestation and LSLA, should develop interventions which reduce forest loss driven either directly or indirectly by LSLA as part of their REDDþ strategies. Both host country and investor-side policies have been identified which could be used more widely to reduce conflicts between LSLA and REDDþ. Findings from this research highlight the need for and can inform the development of national and international policies on land acquisitions including green acquisitions such as REDDþ. Land management must be considered with all its objectivesincluding food security, biodiversity conservation, and climate change mitigation-in a coherent strategy which engages relevant stakeholders. This is not currently occurring and might be a key ingredient to achieve the targets under the Sustainable Development Goals 2 and 15 and 16 (related to food security and sustainable agriculture and the protection of forests) among others.

“…Due to the limited land availability in most countries with biofuel technology, there is pressure on sub‐Saharan African land for biofuel development. The debate on food–land–energy nexus upholds that investments for bioenergy feedstock production are likely to be associated with land acquisitions and increasing competition and pressures on water resources . This holds because, unlike petroleum fuels, there is dual land demand in biofuel development.…”

The micro gas turbine (MGT) technology is gaining momentum in distributed energy solutions. Nevertheless, this technology is predominantly fueled by fossil energy resources at present. The use of biofuels to propel micro gas turbines (MGTs) for power generation is one of the most promising ways to reduce greenhouse gas emission resulting from fossil fuel consumption in power plants and to enhance energy security. Herein, various approaches to integrate biofuels into the MGT system for power generation are reviewed. It is found that biogas‐driven MGTs are in the most advanced stage of technological maturity. From an economic perspective, previous works show that combustion of biogas is most viable in a combined heat and power system compared to only power or heat generation. Nevertheless, the deployment of MGTs for commercial generation of power is scarce, which indicates that this sector is encountering some challenges. One of the major concerns about the exploitation of biofuels in gas turbines relates to fuel properties and combustion characteristics. Other challenges are also presented and discussed, and further research on the commercial production and combustion of biofuels in MGT engines is recommended.
