“…Both pressed samples have higher amounts of C-C/C-H groups compared to the unpressed powder (7 and 18% higher respectively for the 60 and 140 °C). The spirulina cells used in this study are comprised of 54.2-63.1% protein as measured by elemental analysis (CHN), 15% saccharidic carbohydrates and 15% acid-soluble phenolics as determined by high-performance liquid chromatography (HPLC), [30] 1.9-7.8% lipids, [46][47][48] and 1-10% PHA. [15,49] We first consider the dominant biopolymer components (proteins, glucose-based carbohydrates and phenolics) [30] to understand the possible changes in bonding.…”

Since the 1950s, 8.3 billion tonnes (Bt) of virgin plastics have been produced, of which around 5 Bt have accumulated as waste in oceans and other natural environments, posing severe threats to entire ecosystems. The need for sustainable bio‐based alternatives to traditional petroleum‐derived plastics is evident. Bioplastics produced from unprocessed biological materials have thus far suffered from heterogeneous and non‐cohesive morphologies, which lead to weak mechanical properties and lack of processability, hindering their industrial integration. Here, a fast, simple, and scalable process is presented to transform raw microalgae into a self‐bonded, recyclable, and backyard‐compostable bioplastic with attractive mechanical properties surpassing those of other biobased plastics such as thermoplastic starch. Upon hot‐pressing, the abundant and photosynthetic algae spirulina forms cohesive bioplastics with flexural modulus and strength in the range 3–5 GPa and 25.5–57 MPa, respectively, depending on pre‐processing conditions and the addition of nanofillers. The machinability of these bioplastics, along with self‐extinguishing properties, make them promising candidates for consumer plastics. Mechanical recycling and fast biodegradation in soil are demonstrated as end‐of‐life options. Finally, the environmental impacts are discussed in terms of global warming potential, highlighting the benefits of using a carbon‐negative feedstock such as spirulina to fabricate plastics.

“…Bioethanol production involves two main processes: hydrolysis and fermentation. There are many methods for hydrolysis: enzymatic, acid, and base hydrolysis (Kusmiyati et al, 2016;Adekunle et al, 2016). In conventional SHF, hydrolysis is initially performed to convert cellulose into sugars for subsequent fermentation.…”

Bioethanol from agricultural waste is an attractive way to turn waste into added value that will solve the problem of food competition and waste management. Napier grass is a highly productive and effective lignocellulosic biomass, which is an important substrate of the second-generation biofuels. In addition, several processes are required in the production of ethanol from lignocellulosic materials; thus, co-culture fermentation can shorten the production process. This experimental research utilizes Trichoderma reesei and Saccharomyces cerevisiae co-culture fermentation in the bioethanol production of Napier grass using simultaneous saccharification and fermentation technology. To improve ethanol yield, Napier grass was pretreated with 3% (w/w) sodium hydroxide. An orthogonal experimental design was employed to optimize the Napier grass content, mixed crude co-culture loading, and incubation time for maximum bioethanol production. The results showed that pretreatment increased cellulose contents from 52.85% to 82%. The optimal fermentation condition was 15 g Napier grass, 15 g mixed crude co-culture, and 7 days incubation time, which maximizes the bioethanol yield of 16.90 g/L. Furthermore, the fermentation was upscaled 20-fold, and experiments were performed with and without supplemented sugar using laboratory-scale optimal fermentation conditions. The novelty of this research lies in the use of a mixed crude co-culture of T. reesei and S. cerevisiae to produce bioethanol from Napier grass with the maximum bioethanol concentration of 25.02 and 33.24 g/L under unadded and added sugar conditions and to reduce operational step and capital costs.

“…In 2015 the average pineapple production in South Sumatra province was in the range of 59,433 tons / year [6]. With such a large annual pineapple production, it has the potential to produce large amounts of waste from pineapples and can be used as raw material for making bioethanol.…”

The availability of energy from fossil fuels is gradually decreasing. Bioethanol is one of the biofuels which is an alternative energy that can be used as a substitute for petroleum. In Indonesia, in general, the manufacture of bioethanol uses raw materials that compete with foods such as cassava, sugar, and tubers. however, in this research the raw material used is derived from lignocellulosic biomass from pineapple peel. Therefore, this research aims to utilize pineapple peel which is its waste as raw material for making bioethanol through a fermentation process. The fermentation process uses yeast mass and fermentation time as variables where the yeast mass used is 20, 25 and 30 g. while for the fermentation time for 5 and 9 days. In the distillation process, the operating conditions are 78.4 °C for low pressure temperature, and the next step is to analyze the bioethanol produced. Based on the research that has been done, the highest bioethanol content was obtained at 70% with the addition of 25 g of Saccharomyces cerevisiae with a fermentation time of 9 days. From these operating conditions, obtained bioethanol with a concentration of 70%, with a density of 0.8438 gr/mL, and a refractometric index of 9.581.
