AbstractDepletion of world recourses, increasing pollution, and climate change make us shift from linear economy to system economy - an economy of technologies integrated to reach a non-polluting zero emissions production system. Transition to renewable resources requires replacement the present crude oil refinery by biomass refinery. Along with conventional biomass refinery technologies bioengineering and nano-technologies become significant players of systems in the design of clusters of integ...

Biomass is a very interesting natural source to obtain renewable energy as well as chemical products based on a renewable feedstock. Fuel produced from renewable resources is widely regarded as an option to substitute traditional fossil fuels and thus to answer to the adjunct climate debate. For the production of chemical substances from renewable substrates many process options are in investigation worldwide at the moment. However the ecological benefits of these technological options have to b...

The book edited by Haibo Xie and NicholasGathergood focuses on one of the most importantscientific issues of the 21 century which is thereplacing fossil fuel with sustainable alternatives suchas biomass. Fossil fuels are conventional rawmaterials for many industrial sectors includingchemical and energy production. Usage of fossil fuelis limited by their availability, price and carbonfootprint. Biomass is a renewable resource globallyavailable, cheaper and carbon sequestering. Step bystep shiftin...

Abstract Solid digestate (SD) represents an environmental problem due to the continuous increase of biogas production. In the present study four white-rot fungal strains were screened for their ability to grow on two different SD samples, obtained from industrial biogas plants, using wheat straw (WS) as a control medium. Results show that i) the feedstock used in the biogas plant influences the time required for the colonization of the corresponding SD and ii) different fungal strains have d...

Biofuels and biochemicals are currently centre stage in the on-going scientific and political debate. The prevalent opinion is that their use can significantly reduce the greenhouse gases (GHGs) emissions and primary energy demand along their whole value chain. This study aims at evaluating the environmental impact in terms of GHGs related to carbon dioxide (CO2) of secondgeneration sugars (2GSs) production from cardoon residual biomass. Cardoon is a favourable crop in Mediterranean areas for...

The study provides information about separation and identification of natural bioactive compounds from beech (Fagus sylvatica L.) bark with potential therapeutic applications such as antibacterial activity against human pathogens. Beech is a common material used in the wood industry, but its bark is separated from the wood and is considered a by-product. In this study, natural compounds with biological activity were obtained from beech bark by hot water extraction. The high-performance liquid ch...

In this paper, the typical measurement techniques and production procedures defined in the UNI-EN guidelines for ceramic manufacture are taken into consideration to evaluate the properties and the characteristics of the bricks produced by using a mixture containing cubilot slag. The results of the experimental tests demonstrate that these measurement techniques are not enough to define the safety of the waste bricks. Up to now, UNI-EN guidelines for ceramics do not define crystallinity measureme...

Car fluff is an important problem for the industrial compartment, especially for Italy, considering the huge amount of waste produced by the automotive sector, approx. 180.000 ton/year. Although car fluff (CER 191004) is suitable for CSS-Combustible production, with destination to cement factories, a very low amount of it reaches this destination. An alternative way to transform this problem into an opportunity consists into the transformation of bioliquid after its thermochemical transformati...

Citrus is one of the most important fruit tree crops worldwide, with respect to both total production and economic value. About 80% of the world production is destined to the fresh market, the remaining is processed to obtain various products (juices, jams, etc.). Citrus processing residues account for about 50-60% of processed fruits; their huge amounts and peculiar characteristics need a correct management that imply cost for producers and processors. If not well managed, they can represent an...
