Due to high competition in the available space, most cities, including Nairobi, do not have enough space for landfills. Therefore, there is a need for efficient ways to manage the generated waste. Developed countries have embraced Waste-to-Energy technologies, minimizing waste generation and converting generated waste into energy and other resources. Waste characterization is a key element in the energy generation process not only to identify important parameters but also to guide biomass source segmentation. In this study, food wastes were collected from 21 hotels within Nairobi City County, in different mixed ratios and subdivided into five samples for investigation and analysis. The average feedstock characteristics were observed to be moisture content (6.0%, <em>p</em> &lt; .001, <em>R²</em> = 90.70 %), total solid (93.7%, <em>p</em> &lt; .001, <em>R²</em> = 99.97 %), volatile solid (84.3%, <em>p</em> &lt; .001, <em>R²</em> = 99.80 %), ash content (4.2%, <em>p</em> = .005, <em>R²</em>= 48.54 %), fixed carbon (5.4%, <em>p</em> &lt; .001, <em>R²</em> = 88.61%), nitrogen (3.6%, <em>p</em> = .04, <em>R²</em> = 36.81 %), carbon to nitrogen ratio C/N (4.0), crude protein (22.4%, <em>p</em> = .004, <em>R²</em> = 49.36 % ), crude lipids (12.1%, <em>p</em> &lt; .001, <em>R²</em> = 89.06 %), total organic carbon (44%, <em>p</em> &lt; . 001, <em>R²</em> = 94.70%), potassium (0.6%), sodium (1.2%), calcium (0.2%), and phosphorus (0.4%). The potassium, sodium, calcium and phosphorus <em>p</em> and <em>R²</em> values all calculated together were p &lt; .001 and <em>R²</em>= 72.35%. The results showed a significant difference in the means of the samples with the majority of the parameters registering a strong positive correlation of above 50%.

Focusing on cooking and crop production, it examines their contributions to land use changes, mainly deforestation, and emissions. We evaluate three scenarios—BAU, SC1, and SC2- that target clean cooking transitions and reduced crop imports, covering seven crops representing 72 % of Kenya's cultivated area. We detail the challenges of gathering data to populate such a model through document examination and literature review, and we identified uncertain input parameters. Results show that forest loss from cooking varies with the fraction of non-renewable biomass (fNRB). Under BAU, forest cover loss could range from 300 km² at an fNRB of 0.3 to 900 km² at 0.9. Scenarios SC1 and SC2 mitigate these impacts through cleaner cooking solutions. By 2050, under the clean cooking scenario (SC2), LPG stoves could achieve up to 96 % penetration, reducing CO₂ emissions to 8.3 MTon and PM_2.5 to 0.8 kTon, compared to high emissions in the BAU scenario dominated by wood and charcoal stoves. In agriculture, land use expands by 56 %, 69 %, and 33 % across the scenarios, while fossil fuel use rises from 2.46 PJ to 5.9 PJ by 2050, increasing CO₂ emissions, from 183 kTon to 436 kTon.

These fuels can deal with the concerns about energy security through the diversification of the energy mix and mitigation of dependence on expensive imported fossil fuels. Given the ongoing energy shortages, inadequate policy frameworks, and escalating energy demands prompted by population growth and industrial expansion, biofuels have emerged as a sustainable solution. Therefore, this study tries to investigate the biofuel production and adoption drivers employing an integrated multi-criteria decision-making (MCDM) approach. Specifically, it combines the interval-valued type 2 intuitionistic fuzzy (IVT2IF) theory and the decision-making trial and evaluation laboratory (DEMATEL) method to determine, rank, and assess the correlation among the drivers that affect the sustainable production and adoption of biofuel in emerging economies like Bangladesh. The drivers were initially extracted through a systematic literature review of the existing literature. Followed by expert validation, 17 drivers were chosen for analysis utilizing the IVT2IF-DEMATEL technique. The findings suggest that \"facilitating advanced R&amp;D and efficient training regimen\", \"promoting technological advancements\", \"enhanced energy security and resilience,\" and \"development of the diversified renewable energy mix\" are the most significant drivers, with prominence values 15.616, 15.467, 15.164, and 15.067, respectively. Furthermore, \"streamlining bio-waste management processes\" holds the highest significance as a causal driver (with a causal weight of 1.290), which is trailed by \"commercialization of biofuel retrofits\" and \"efficient agricultural resource management\" (which have causal weights of 0.696 and 0.505, respectively).

RE faces multiple risks and challenges, so these risks need to be evaluated and mitigated such as technical risks, environmental risks, security risks, policy risks, and technological risks. This study proposed a multi-criteria decision-making (MCDM) method for assessing RE risks. The MCDM method is integrated with neutrosophic sets (NSs) to deal with inconsistent data in the evaluation process. Two MCDM methods are used in this study: Entropy and Ranking of Alternatives with Weights of Criterion (RAWEC). The neutrosophic entropy is used to compute the criteria weight, and the neutrosophic RAWEC method ranks the alternatives. This study applied the proposed method to two case studies. In the first case study, the RE risks are ranked. In the second case study, various strategies are proposed by blockchain, artificial intelligence (AI), the Internet of Things (IoT), big data, and zero-trust to reduce RE risks. There are six main factors; 31 sub-factors and 19 risks are used in the first case study, and 19 factors and 20 strategies are used in the second case study.

The regression cluster analysis reveals significant differences in the impact of these energy sources on emissions across the EU. In particular, gas, coal and oil all have positive and significant coefficients, with coal having the largest impact on CO₂ emissions across all clusters.

Seven salinity indices (SI-1 to SI-7) were derived from the 10m to 20m wavelength bands of Sentinel-2, along with vegetation and topographic covariates. Initially, Recursive Feature Elimination was implemented as a feature-selection method to select the most effective predictors.

Three fertilizer rates and five bioinoculants were evaluated in a split-plot design with three replications. The result revealed that, application of recommended rate of fertilizer (RRF) recorded ∼22.13 % and 82.49 % higher yields than 75 % and 50 % RRF, respectively. The highest gross returns (₹ 80,412 ha^-1), net returns (₹ 50,511 ha^-1) and benefit-cost ratios (2.68) were also found higher with RRF. Likewise, plots applied with RRF even increased the seed oil content (50.9 %), oil productivity (722 kg ha^-1), and rain-water use efficiency (1.60 kg ha^-1 mm^-1). The plots treated with RRF required in 8.12–18.64 % higher energy input (12,275 MJ ha^-1) over 75 % and 50 % RRF, respectively.

Using a technological readiness perspective, the current study evaluates its technological maturity and potential to achieve full commercialization. Based on a structured literature review including 70 recent publications on the topic, the current study identified four main techno-economic barriers that stand in the way of this eco-innovation progressing to wide-scale adoption: (1) a low power density and energy efficiency; (2) a high levelized cost of energy; (3) technological immaturity; and (4) a lack of competitiveness. The technological immaturity of combined seawater desalination and reverse electrodialysis technology is one of the prime reasons for the low power density and energy efficiency, which in turn has a causal relationship with the high costs associated with the technology. Additionally, the high costs may contribute to the lack of competitiveness. It is concluded that these main barriers might cause the eco-innovation to fall victim to the so-called \"Valley of Death,\" a funding gap between the proof of concept within academia and the adoption of the technology by the industry on a commercial scale.
