Rising energy prices and depleting reserves of fossil fuels continue to renew interest in the conversion of biomass to biofuels production. Biofuels derived from renewable feedstocks are environmentally friendly fuels and have the potential to meet more than a quarter of world demand for transportation fuels by 2050. Moreover, biofuels are expected to reduce reliance on imported petroleum, redu...

Palm oil solid wastes consist of cellulose, hemicellulose and lignin. In this study, a single stage of acid hydrolysis process of palm oil empty fruit bunch (EFB) for production of fermentable sugar was carried out under moderate temperature (45°C) and ambient pressure. The effect of four different process variables such as solid size, HCl concentration, solid percentage and temperature were in...

Background With growing concern in obtaining clean and renewable energy, many works in bioenergy has been developed in order to obtain substantial gains for the environment. Due to the large environmental impact associated to the use of fossil fuels, ethanol production from lignocellulosic materia lhas been widely explored, aiming environmental, economic and social benefits. Lignocellulosic bio...

Renewable and low-cost lignocellulosic wastes have attractive applications in bioethanol production. The yeast Saccharomyces cerevisiae is the most widely used ethanol-producing microbe; however, its fermentation temperature (30-35°C) is not optimum (40-50°C) for enzymatic hydrolysis in the simultaneous saccharification and fermentation (SSF) process. In this study, we successfully performed an...

background and purpose: it is extremely important to recognize the qualitative and quantitative characteristics of this type of waste before any planning on them due to the lack of the prepared program in the field of household hazardous waste (hhw) management in the country. this research has been done in babol, iran, in order to achieve this important goal. materials and methods: the cross-se...

BACKGROUND The aim of the study was to design and implementation of integrated solid wastes management pattern in Shahroud industrial zone, evaluates the results and determine possible performance problems. This cross - sectional study was carried out for 4 years in Shahroud industrial zone and the implementation process included:1- Qualitative and quantitative analysis of all solid waste gener...

Plasma pyrolysis integrates thermo-chemical properties of plasma using pyrolysis process for safe disposal of solid wastes. It is an environment friendly technology to generate valuable byproducts by converting municipal solid waste, biomedical waste and hazardous wastes at 800-1000°C. Plasma Pyrolysis of plastic wastes generates pyrolysis gas, which can be utilized for energy recovery via diff...

Improper disposal of lignocellulosic wastes may produce a large quantity greenhouse gases and pollute the environment. Through anaerobic digestion processes, can be recycled to clean renewable biogas. However, lignin in lignocellulose limits its potential as such biomass resource, efficacy biogas production is not satisfactory although recent research efforts have attempted address this issue. ...
