Abstract:

As the fossil energy decrease such as petroleum and natural gas, that are encourages a lot of research to develop new sources of energy from renewable raw materials. One of the source is through reducing sugar (glucose and xylose) obtained from coffee pulp waste; this is due to abundant production of coffee pulp every year reaching 743 kg/ha. In addition, this waste has not been used optimally and the cellulose and hemicellulose content of the coffee is high. The purpose of this study is to get the optimal operating condition for reducing sugar production from coffee pulp waste. The method use

Abstract:

Polyhydroxyalkanoates (PHA) are biodegradable polymers that are considered able to replace synthetic plastic because their biochemical characteristics are in some cases the same as other biodegradable polymers. However, due to the disadvantages of costly and non-renewable carbon sources, the production of PHA has been lower in the industrial sector against conventional plastics. At the same time, first-generation sugar-based cultivated feedstocks as substrates for PHA production threatens food security and considerably require other resources such as land and energy. Therefore, attempts have b

Abstract:

Plant oils represent one of the most energyrich sources of renewable fuels available in Nature. Most of these oils occur in the form of triacylglycerols (TAGs) that can be transformed into biodiesel by conversion of their acyl chains into fatty acid methyl esters. In 2009, 14 billion litres of biodiesel were produced worldwide from plant oils (largely in the EU). This compares with 70 billion litres of ethanol (largely from Brazil and the USA). Both of these fuels now depend on land and crops (e.g. oil seeds, palm trees, maize and sugar cane) that are also used for foods. To meet growing deman

Bioenergy refers to renewable energy produced from biomass. Biomass is any organic material which has stored sunlight in the form of chemical energy. Depleting fossil fuel reserves and growing demand for energy has necessitated the renewed search for alternative energy resources such as plants. Biofuels are an alternative to fossil fuels, which are liquid or gaseous fuels that are derived from biomass sources. Biofuels can be used alone or in combination with other fossil fuels such as petrol. Biofuels are classified into first, second and third generation biofuels. In this review paper, empha

Yeasts were isolated from four potential sources, sweet sorghum juice, sugar cane juice, grapes and rambutan. The 27 yeast isolates were tested for their ethanol tolerance (15% v/v of ethanol) and ethanol fermentation performance in a synthetic ethanol production medium (200 g/L of total sugar). Only five isolates, SCJ04KKU, SCJ07KKU, SCJ09KKU, SCJ14KKU and SSJ01KKU could tolerate 15% ethanol and produce ethanol at levels higher than 55 g/L.

Abstract:

Access to clean and non-polluting energy has been defined as a Sustainable Development Goal (SDG). In this context, countries such as Colombia have promoted policies and incentives for the implementation of energy projects with non-conventional sources of energy. One of the main energy alternatives available is related to the use of residual biomass left by agribusiness supply chains, such as sugarcane. In Colombia, sugar cane is grown and harvested all year round, due to the local tropical climate. The model we propose addresses the question of the selection of the plots whose crop residue wi

Fossil fuels are included as non-renewable energy sources, so its presence in Indonesia is decreasing. One of the renewable energy sources that can be obtained easily is bioethanol, this energy is obtained from organic materials containing cellulose fibers. Cellulose is hydrolyzed on a catalyst and fermented to obtain bioethanol. The aim of this study was to determine the effect of variations in the concentration of catalysts in the production of bioethanol from market organic waste (fruit peels and vegetables).
