Compared to terrestrial biomass, marine algae have a major potential to become a renewable resource of raw material for biofuels and bioproducts. Through their diverse chemical composition, marine algae can be the source of bioproducts for many industries. For the implementation in practice of the marine algae capitalization, it is necessary to obtain supplementary information from scientific research and solving some technological aspects for obtaining bioproducts under efficient economic conditions.]]>

The pulp and paper industry is based on the use of renewable and recyclable raw materials. At the same time, this industry has begun to implement biotechnological processes alongside the chemical ones, increasing also the degree of computerization. Concerns about increasing economic efficiency and increasing yield of valorisation have led to the idea of applying the principles of biorefining. Under these conditions, the pulp and paper industry can offer alternative sources of energy and bio-products. In this paper are presented some directions in which by the recycling of the waste paper results secondary products that can be used as sources of energy, materials and bioproducts]]>

One of the great challenges to our society in the future is to find a sustainable manner to obtain bio-based products biofuels and chemical products) from renewable resources. From this point of view, biomass resulted in silviculture, agriculture from cultivation or as by-products from processing industries, wastes from exploitation or municipal wastes may be considered. The use of biomass as energy and chemicals source has the following advantages: (1) is an indigenous source and therefore it assures reducing dependency on import and increasing security in supplying (most of the resources there are in the political instability zones); (2) as in the case of other renewable sources, the biomass offers a great potential to create new jobs in agriculture, silviculture and environmental protection. (3) the technologies used to obtain renewable carriers of energy ofers promising opportunities for businesses because it is expected the increasing consumption of energy an chemical products; (4) in many industries biomass is a by-product resulted in the processing and its use will can solve the problem of wastes and energy or chemical products. In this paper a model is presented which allow both assurance and development of resources, and their valorization by biorefining, which can be translated at the level of small and medium enterprises.]]>
