“…If the proportion of the size of the installation is not adjusted to the possibility of obtaining the raw material, the capital costs are too high, which reduces the profitability of the investment and extends the payback period [54,56]. The rate of return determined in some studies for commercial biogas plants varied from 10 to 60% under the same external conditions [57], and for very small household biogas plants in Bangladesh, it was on average around 40% [58]. The results that present the profitability of biogas plants operated by enterprises are not clear.…”

Determinants of Return-on-Equity (ROE) of Biogas Plants Operating in Poland

Poland has a large potential for biogas production from agricultural sources and food waste. This potential is still poorly used. There are many reasons for this state of affairs. We can indicate both the policy of the state towards renewable energy sources (RES) with a small amount of energy from biogas contracted at auctions, investment risk, and especially low return on investment in the absence of investment support. An important reason is also the limited state budget. The purpose of this work was to determine the endogenous factors that determine ROE, the direction of the impact of these factors, as well as the strategy of biogas plants in shaping the ROE level. The DuPont model was used in the analysis of ROE changes. We used the deviation method to determine the impact of the various factors on ROE. Against the background of the energy sector in Poland, the value of ROE in the examined biogas plants should be considered satisfactory, and in 2020 it was, on average, 13.9%. The decrease from 17.2% in 2019 occurred despite the increase in energy prices and the increase in the net profit margin (NPM). It resulted from the reduction of ROE’s financial leverage through external capital. A high level of debt characterized the examined biogas plants, and the pursuit of risk reduction and debt reduction negatively impacts on ROE. This may indicate the need for state investment support at the plant construction stage or low-interest investment loans to develop biogas plants. In addition, using only price guarantees under the feed-in tariffs, with dynamic changes in costs, may bring the industry a relatively high investment risk compared to other RES, where the operational costs during the lifetime are low, as it is in PV or wind systems.

“…The largest waste from cocoa bean processing is the cocoa husk or cocoa pod, which accounts for 75% of the total fruit [3]. Many cocoa pod husks will be advantageous if used as raw material to synthesize ethanol or biogas [4], [5]. The most significant component of the cocoa rind is carbohydrates.…”

Cocoa-producing nations, including Indonesia, play a pivotal role in global cocoa production, with cocoa beans as a primary agricultural commodity. Despite this, cocoa pod husks (CPH) have historically been dismissed as household waste. This study investigates the untapped potential of CPH for bioethanol production, focusing on the influence of fermentation duration on hydrolysis products. Using 1.5 N sulfuric acid, cocoa pods underwent a 120-minute hydrolysis with a 1.9 g/mL concentration/solvent ratio. Subsequent fermentation involved a 10% Saccharomyces cerevisiae starter culture at 30°C and pH 5 under anaerobic conditions. Mass chromatography spectroscopy revealed a progressive ethanol increase, peaking at 4.21% volume on the seventh day, and a substantial reduction in remaining sugar content from 18.45% to 5.53%. These findings underscore the correlation between prolonged fermentation and enhanced ethanol production. The study highlights CPH's potential as a valuable resource for sustainable bioethanol production, reducing waste and offering a renewable energy source. Emphasizing resource optimization and environmental stewardship in agriculture, this research aligns with the global demand for eco-friendly alternatives in the energy sector.
