“…There is no question about the importance of irrigation technologies in relation to economic management of natural resources due to climate change, especially drip irrigation is increasing resource efficiency significantly [67].One big problem of this system is the high use of different types of plastic, the short life of the material and difficulties to retreat all materials and parts of the system from the cropland after the end of the production cycle [70]. Furthermore, plastic products require an accurate storage to avoid different tips of contamination and degradation in rivers, lakes and the ocean to microplastics [71]. Therefore, materials for drip irrigation systems require also accurate storage to avoid soil contamination by damaged and degraded system parts, which could be blown away by wind and be mixed with soil during cropland preparations [72].…”

The expansion of food production is getting more important due to a rising world population, which is relying on food security on a regional and local scale. Intensive food production systems create a negative impact on the regional ecosystem because of agrochemical pollution and nutrient rich water discharges into nearby rivers. Furthermore, these systems are highly depending on regional water resources causing water scarcity and soil erosion due to the overexploitation of natural resources in general. The objective of this article is to review the water usage in the two most water intensive food production systems, agriculture and aquaculture showing lacking areas, like system management and climate change, which must be considered in the implementation of sustainable water footprint. In addition, the review includes an analysis if the combination of both production system into aquaponic food production and the possibilities of water saving. There are a variety of water footprint analyses for crop and aquatic animal production, but there is also a lack of information about the system management including irrigation systems, system cleaning processes, water substitution, pond removal, evaporation due to climate change and especially in aquaculture, the water footprint of industrial elaborated fish feed.

“…However, the use of plastics is associated with many environmental impacts related to their production and poor waste management practices [2]. It is important to find a new way to recycle and reuse these plastics, as there are millions of tons of used plastics accumulating in the natural environment [3,4]. Plastic pollution damages the environment, human health, and the economy of various countries.…”

The recycling of waste materials is a way of limiting over-consumption and optimizing the value of resources. Within the framework of a circular economy, this can be applied to post-consumer plastic wastes, but also to biobased by-products. Hence, this work deals with the design of composite materials by combining recycled high-density polyethylene (HDPE) and polypropylene (PP) coming from bottle caps and virgin cork of insufficient quality for cork stoppers. Different fractions (0, 5, 10, 15, and 20 wt%) of virgin cork were incorporated into recycled polymers (HDPEr and PPr). These composites were prepared without a coupling agent or fire retardant. The morphology and mechanical properties of the different conditionings were studied and compared. The thermal decomposition and the fire behavior of the composites were also investigated. Microscopy revealed the poor adhesion between the cork particles and polymer matrices. However, this limited interaction affected only the tensile strength of the PPr composites, while that of the HDPEr composites remained almost constant. The addition of cork was shown to reduce the time to ignition, but also to promote charring and reduce the heat released during the composite’s combustion. The feasibility of composites based on cork and HDPEr/PPr waste opens the way for their reuse.
