Climate Change Education in Finland
The climate change education (CCE) is understood as a component of environmental education and education for sustainable development. Its core concept is CC literacy, which means that students understand the scientific concepts related to CC and the relationships between them, as well as the effects of CC and their own activities on the environment. CCE is multidisciplinary and interdisciplinary. Multidisciplinarity means that knowledge of various individual sciences is needed. Interdisciplinarity, on the other hand, incorporates elements from a variety of disciplines and also integrates environmental, economic, social and political issues.

Applications of Polysaccharide Stalks in Didymosphenia geminata Diatom
Didymosphenia geminata is a species of freshwater diatom that is known as invasive and is propagating quickly around the world. The polysaccharide-based stalks of D. geminata enable versatile potential applications and use as a biopolymer, in drug delivery and wound healing, and as biocompatible scaffolding in cell adhesion and proliferation. Furthermore, the polysaccharide nature of stalks and their metal-adsorption capacity allow them to have excellent wastewater remediation potential.

Lemongrass Essential Oil
Cymbopogon spp. are fast-growing C4 perennial sedges from the grass family Poaceae and are primarily cultivated for their essential oils. The genus lemongrass comprises about 180 species, such as Cymbopogon citratus, Cymbopogon flexuosus, Cymbopogon winterianus, Cymbopogon martinii, Cymbopogon nardus, and Cymbopogon refractus. Lemongrass (Cymbopogonspp.) oil is a cocktail of various terpenes and terpenoids, out of which the major components belong to cyclic and acyclic monoterpenes. The monoterpenes are derived from geranyl diphosphate (GPP).

Carbon Dioxide Capture
Carbon capture is among the most sustainable strategies to limit carbon dioxide emissions, which account for a large share of human impact on climate change and ecosystem destruction. This growing threat calls for novel solutions to reduce emissions on an industrial level. Carbon capture by amorphous solids is among the most reasonable options as it requires less energy when compared to other techniques and has comparatively lower development and maintenance costs. In this respect, the method of carbon dioxide adsorption by solids can be used in the long-term and on an industrial scale. Furthermore, certain sorbents are reusable, which makes their use for carbon capture economically justified and acquisition of natural resources full and sustainable. Clay minerals, which are a universally available and versatile material, are amidst such sorbents. These materials are capable of interlayer and surface adsorption of carbon dioxide. In addition, their modification allows to improve carbon dioxide adsorption capabilities even more.

Construction Waste Recycling
Construction waste is an issue that has attracted increasing worldwide attention recently. With the rapid development of socioeconomic and urbanization in China, the building industry has emerged as a pillar of the national economy. In particular, a large number of raw materials are used and massive construction waste is generated along a gradient of increasing urbanization, resulting in environmental pollution and scarcity of nature resource. At present, construction waste recycling has been proven to be the most effective method of managing construction trash.

Textile Recycling
Textile reuse consists of the various methods of prolonging the useful service life of textile products from one owner to another. Renting, trading, swapping, borrowing, and inheriting are commonly practiced, which are facilitated by second-hand stores, garage sales, online stores and flea markets, and charities. On the other hand, textile recycling refers to reprocessing pre-consumer and post-consumer textile waste for use in new textile or non-textile products. Various textile recycling technologies such as fiber regeneration, conversion of textile waste into insulation/building materials, fermentation, anaerobic digestion, composting, and thermal recovery are available and progressively improved. Textile reuse and recycling offer environmental sustainability and can reduce environmental impact by reducing the use of virgin textile fiber and avoiding processes further downstream in the textile product life cycle.

Evaluation Index System for Mine Ventilation System
The mine ventilation system is an indispensable component to improve coal mining efficiency and ensure the safety production. Only by clearly grasping the comprehensive evaluation quality of ventilation system can effective countermeasures be formulated. This paper establishes an evaluation index system for mine ventilation system by combining qualitative survey with quantitative research. Specifically, the primary indicators are screened through R-type clustering and coefficient of variation method. The weight of each index is determined by the entropy weight method. Moreover, the TOPSIS method are used to evaluate the quality of the mine ventilation system. Finally, this evaluation system is used to evaluate the ventilation renovation project in the production mining area of the Sihe mine. The evaluation results verify the effectiveness of the establishment of mine ventilation evaluation index system and evaluation methods.

Durability of Recycled Fine Aggregate Concrete
In recent years, scholars around the world have worked on improving recycle aggregates in concrete and broadening the scope of applications of recycled concrete. The findings of research on the effects of recycled fine aggregates (RFAs) on the permeability, drying shrinkage, carbonation, chloride ion penetration, acid resistance, and freeze–thaw resistance of concrete has been reviewed. The results show that the content of old mortar and the quality of recycled concrete are closely related to the durability of prepared RFA concrete.

A city Multi-Floor Manufacturing Cluster
Multi-floor manufacturing cluster (MFMC) comprise production and service enterprises of various types of ownership, mainly SMEs, with different production orientations, with the presence of small-scale in-house equipment. This feature of MFMC promotes business competition, allowing for creating collaborative and networked organizations that can happen at some stages of development and can reach a level of a virtual manufacturing network based on Digital Twins models to fulfil customer orders.
