Coastal countries have traditionally relied on the existing marine resources (e.g., fishing, food, transport, recreation, and tourism) as well as tried to support new economic endeavors (ocean energy, desalination for water supply, and seabed mining). Modern societies and lifestyle resulted in an increased demand for dietary diversity, better health and well-being, new biomedicines, natural cosmeceuticals, environmental conservation, and sustainable energy sources. These societal needs stimulated the interest of researchers on the diverse and underexplored marine environments as promising and sustainable sources of biomolecules and biomass, and they are addressed by the emerging field of marine (blue) biotechnology. Blue biotechnology provides opportunities for a wide range of initiatives of commercial interest for the pharmaceutical, biomedical, cosmetic, nutraceutical, food, feed, agricultural, and related industries. This article synthesizes the essence, opportunities, responsibilities, and challenges encountered in marine biotechnology and outlines the attainment and valorization of directly derived or bio-inspired products from marine organisms. First, the concept of bioeconomy is introduced. Then, the diversity of marine bioresources including an overview of the most prominent marine organisms and their potential for biotechnological uses are described. This is followed by introducing methodologies for exploration of these resources and the main use case scenarios in energy, food and feed, agronomy, bioremediation and climate change, cosmeceuticals, bio-inspired materials, healthcare, and well-being sectors. The key aspects in the fields of legislation and funding are provided, with the emphasis on the importance of communication and stakeholder engagement at all levels of biotechnology development. Finally, vital overarching concepts, such as the quadruple helix and Responsible Research and Innovation principle are highlighted as important to follow within the marine biotechnology field. The authors of this review are collaborating under the European Commission-funded Cooperation in Science and Technology (COST) Action Ocean4Biotech – European transdisciplinary networking platform for marine biotechnology and focus the study on the European state of affairs.
For the next century to come, one of the biggest challenges is to provide the mankind with relevant and sufficient resources. The recovery of secondary resources plays a significant role. The industrial processes developed for regaining minerals for production of commodities in a circular economy become ever more important in the European Union and worldwide. Landfill mining (LFM) constitutes an important technological toolset of processes that regain the resources and redistribute them with an accompanying diminishment of hazardous influence of environmental contamination and other threats for human health hidden in former dump sites and landfills. 'Classical LFM' is a useful technology to discover hidden resources and look at the big picture of resources in the local, regional and global perspective. Therefore, this paper considers development of paradigms and attitudes to LFM as the technology for regaining calorific value; the furthering of deposited material valuable to more advanced concepts of enhanced LFM (ELFM); the recovery of landfill space and land value, and, finally, the possibility of full ecosystem services revitalization. The future of our civilisation depends on our wise use of commodities. Thus, waste operations beyond the Zero waste concept must be applied if mankind is to conquer space and the abyssal plains to conduct mining in the deepest oceans on the Earth. Other research areas feasible for LFM in terms of the environmental rehabilitation are given in the review. This compilation summarises the previous, current and future trends of LFM 2 technology regarding the paradigm developments that are influencing the attitude of scientists, industry and society to LFM as a complex tool for implementing the circular economy in practice. This review paper is based on a historical overview of global case studies and explores the methodology of waste management as regards the different tools for geochemical, geophysical and remote sensing that are used for field studies prior to the decisions whether LFM will be successful in an individual case. New technological developments of ELFM for the energy industry is described combined with a review of innovative material production. One chapter is dedicated to the Efficient Use of Resources and Optimal Production Economy (EUROPE) estimation model. The hazardous impacts of landfills, such as greenhouse gas emission and pollutants, are discussed. Throughout history, the major part of the 'LFM economy' has been viewed from a point of view of recovery of natural resources. Therefore, our main philosophy was to provide a historical experience linking with modern ideas of LFM to the increasingly relevant concept of a circular economy. The world is heading towards a restricted access to key resources. However, humanity should not limit itself to frame these restrictions but should also have a profound view on the global economy and life styles for future generations from an environmental and non-material resource standpoint. It is concluded that the big ...
For decades, significant work has been conducted regarding plastic waste by dealing with rejected materials in waste masses through their accumulation, sorting and recycling. Important political and technical challenges are involved, especially with respect to landfilled waste. Plastic is popular and, notwithstanding decrease policies, it will remain a material widely used in most economic sectors. However, questions of plastic waste recycling in the contemporary world cannot be solved without knowing the material, which can be achieved by careful sampling, analysis and quantification. Plastic is heterogeneous, but usually all plastic waste is jointly handled for recycling and incineration. Separation before processing waste through the analytical approach must be applied. Modern landfill mining and site clean-up projects in contemporary waste management systems require comprehensive material studies ranging from the macro-characterization of waste masses to a more detailed analysis of hazardous constituents and properties from an energy calorific standpoint—where, among other methods, thermogravimetric research coupled with life cycle assessment (LCA) and economic assessment is highly welcomed.
