Abstract:

Abstract Biomass conversion methods represent bioeconomic solutions for the sustainable production of value added commodities (chemicals and materials) as well as for energy purposes, either in solid (pellets), liquid (transport fuels) or gaseous (combustion gases e.g. biomethane) form. Lignocellulosic biomass as a renewable source available in immense quantity, is considered to be one of the most promising natural sources, with high potential in the replacement of conventional transportation fuels and reduction of greenhouse gas emissions. This thesis provides new insights into mechanocatalys

Abstract:

Barley straw, an agricultural byproduct, was identified as a potential adsorbent material for wastewater treatment as it offers various advantages such as abundant availability at no or very low cost, little processing cost and ability to biodegradation. The raw barley straw, however, needs to be modified as a preliminary study showed less favorability of the raw barley straw in removing oil and anionic dyes. Barley straw was chemically pretreated with sodium hydroxide and modified using a cationic surfactant, hexadecylpyridinium chloride monohydrate (CPC).Generally, the treatment with NaOH in

Abstract:

Algal and cyanobacterial1 blooms are increasingly becoming a problem to water utilities in the UK and around the world. Conditions such as increasing eutrophication and poor management of water bodies are consequently leading to increases in the number and severity of algal bloom events. These blooms present serious issues to both utilities and the environment; problems include deoxygentation of water bodies leading to fish kill and rapid algal growth leads to overgrowing of other plant species in the water, while blooms of toxic cyanobacteria can lead to the closure of reservoirs and a number

Abstract:

In the world today there is a massive dependency on fossil fuels as they are currently used to provide around 80% of the world’s energy. This is hugely detrimental to the environment and is a major contributory factor in climate change. Biofuel is a renewable energy source that is already being used to lessen some of the fossil fuel dependency. 2nd generation biofuels, by using non-food parts of plants, circumvent the food vs fuel argument, and by using farming waste or surplus can also avoid changing land use problems. Additionally liquid biofuels can use existing infrastructure for storage a

Abstract:

Experiments were conducted in Avra Valley, Arizona, to study the use of digested liquid sewage sludge as a source of plant nutrients in the commercial production of grain and straw from wheat. Wheat grown with the recommended amount of plant -available nitrogen from sewage sludge produced the same grain yield as wheat grown with the same amount of nitrogen from inorganic fertilizer. Wheat grain and straw grown with sewage sludge and inorganic fertilizer had similar livestock feeding qualities. Fertilizing wheat with sewage sludge delayed maturity.

Abstract:

The incorporation of cereal straw/stubble often immobilises nitrogen (N). This can help conserve N in soil in organic forms, thus reducing loss through leaching over dormant winter periods. However, N-depressions that arise during decomposition can reduce crop yield. The inclusion of a legume green manure can supply fixed-N, thus alleviating the low N availability to crops. In this study, the effect of lupin (Lupinus angustifolius L.) green manure incorporation on barley (Hordeum vulgare L.) straw/stubble decomposition, and N availability was investigated.

Abstract:

Cyanobacteria are present in most water bodies and sometimes grow to large populations known as blooms. Some of these cyanobacteria are also capable of producing toxins which can be fatal to livestock and humans. The production of cyanobacterial toxins is not specles-, but gene-specific, so the prediction of toxicity based on identification of the cyanobacteria using morphological characteristics is unlikely to be reliable. A better way to predict the likely toxicity of a bloom is the use of molecular techniques to detect the genes for toxin production and this was the approach taken in the fi

A large part of energy carriers and chemicals of our society come from fossil fuels; due to their critical exploitation and environmental concerns, alternative solutions should be promoted. The goal of this work is to understand the environmental impacts of different supply chains of levulinic acid production. To enable this comparison, a cradle-to-gate LCA was conducted on different kinds of biomasses, under an innovative thermochemical process called Biofine.

Abstract:

The energy requirements of the world has accelerated search for new fuels or new sources of fuel. Ethanol or butanol production from lignocellulosic biomass is one example of this. As lignin constrains the access of cellulose or hemicellulose to enzymes for their hydrolysis, it is necessary to remove the lignin. Various pretreatment methods are used before going for the hydrolysis of cellulose present in biomass followed by hydrolysis. In this work, barley straw is chosen as the lignocellulosic biomass and production of butanol has been carried out using steam explosion and acid hydrolysis fol
