In the present study, twenty-seven fungal species were isolated, purified, and identified from five mixed soil samples collected from Tanta City, Gharbia Governorate, Egypt. The isolated fungal species belonging to nine genera i.e. Aspergillus, Cephalosporium, Fusarium, Penicillium, Botritrichom, Trichoderma, Alternaria, Cladosporium and Scopulariopsis, in addition to two white rot fungi Ganoderma lucidum and Lentinus edodes obtained from Mushroom Laboratory Culture Collection (MLCC), El-Giza, Egypt. The ligninolytic activities of the isolated fungi were evaluated on PDA plates containing 0.02% guaiacol as a chromogenic reagent. Out of the twenty-nine fungal species, only three fungi G. lucidum, L. edodes and T. harzianum (isolate 2) showed ligninolytic potential and reddish-brown color zone formed due to guaiacol oxidation. The three positive fungal strains were screened quantitively for Laccase (Lacc), Manganese dependent peroxidase (MnP), and Lignin peroxidase (LiP) activities. The highest total ligninase activity was recorded by G. lucidum followed by L. edodes and T. harzianum, respectively.      

Plastic trash has numerous negative effects on the ecosystem. Plastic's threat to the environment is exemplified by the territories set aside for plastic trash dumps. As a result of the accumulation of vast volumes of waste, the presence of microorganisms that speed up the biodegradation of plastics grows, resulting in the formation of methane, a gas that is a major contributor to global warming. The accumulation of plastic bags, food containers, and empty containers at the bottom of the ocean exposes oceans and aquatic life to the dangers of plastic pollution on the marine ecosystem. Over time, the waste is broken down into smaller pieces, causing further harm to the fish eating it and contaminating their tissues. Plastic is an integral aspect of modern living, despite the negative impacts of plastic trash on the environment and marine life. When compared to current plastic waste management, global plastic output reached 314 million tonnes in 2014 and is anticipated to reach more than 1200 million tonnes by 2050. In the United States, 75% of plastic is discarded in landfills, 16% is burned, and only 9% is recycled. This review focuses on types of waste plastics, the different methods of waste plastic recycling and the harmful and useful impacts of waste plastic recycling. In addition, waste plastics recycling according to sustainable development vision globally. Key words: Waste plastics, Recycling, Environmental impacts, sustainable development.      

Abstract. Nowadays climate change is one of the most important global issues that must be focused on. As the buidings operations and building materials & construction sector represents 39% of global CO2 emmision that causes climate changes. It was necessary to bear these climatic changes in mind when thinking about constructinf different kind of buildings uses. Shippingcontainers is a modular repetitive unit that have many advantages, which qualifies them to become a sustainable, environmentally friendly building unit, which contributes to reducing the negative effects of climate change. The use of shippingcontainers in the field of architectural design and buiding construction for various uses in Egypt, despite its many uses in many different places around the world, is still a new idea that has not been widely spread in Egypt it was only applied on a small scale of some light structures buildings. Hence, it was necessary to draw attention to that repetitive modular unit, as a step on the way for building sustainable Eco-friendly buildings to face climate changes in Egypt. This research tackels the advantages, disadvantages and importance of shippingcontainers, its construction materials, its cost, and mentions the most suitable places in Egypt that shippingcontainers can be built as will be stated in the theoretical part. The analytical part is concerned with presenting experiences and examples of different types of buildings in which shippingcontainers were used as a basic building unit to clarify the extent of their sustainability and advantages. The research concludes with a set of results and recommendations that support the idea of using shippingcontainers as a recycled modular building unit that contributes to reducing climate impacts and construct sustainable, Eco- friendly buildings in Egypt. Key Words: Climate Change, Modular Shipping Containers, sustainability, Eco-friendly Buildings      

Integrated water management aims to promote water supply not only from conventional sources but also from wastewater reuse in part to address issues such as water scarcity. The positive input from collection and reuse of water for household purposes has not often seen assessments of the impact of climatic change, water resource availability and water deprivation in several countries. If the source water comes from a clean water source and was first used to wash or bathe it is commonly referred to as "graywater." Grey-water is an abundant resource generated throughout the life of people. Grey-water can be used for domestic cleaning, flushing toilets, washing vehicles, washing kitchen gardens, clothes washing and washing before rinsing. The main objective is development of an experimental system for greywater treatment with the optimum cost and reuse it in the buildings facilities. This study shows that the presented experimental study, that uses a conventional process of treatment built with existing systems, can achieve relatively good results of greywater treatment, particularly in filtration by mixture between screen filter and gravel filter.      

Root-knot nematodes (RKNs) (Meloidogynespp) is the most economically destructive species. A pot experiment was conducted to assess the suppressing potential of three vermicompost types of different plant residues origin on (RKNs) (Meloidogyne incognita) in tomato cultivar by inoculation in prepared soil. Three vermicompost types CD (Cow dung) alone; CD mixed with either Taro Leaves (TL) or Saw Dust (SD) as carbonaceous sources were prepared for this study. Results revealed an overall significant increase in RKNs infected plants growth parameters in the vermicompost (SD + CD and TL+ CD) inoculated soil. Whereas, markedly increments were observed in root, shoot length and number of lateral roots besides their marvelous effect on controlling the RKN infection and blocking it to be restricted to the outer layer of vascular bundle. Our findings elucidated that different plant wastes origin vermicompost types have noticeable effects on RKNs infected tomato plants. The applied vermicompost (CD with either SD or TL) is serving not only as bio-organic fertilizer but also as effective bio-controlling treatment for root-knot nematodes and has no negative effect on the environment      

As a result of the increase in population, many areas face serious and fundamental problems in the availability of water and water quality. Besides the industrial progress, this led to multiple sources of contaminants, so it is necessary to treat polluted water with low cost/safe way. On the other hand, the environment is deteriorating due to the increasing density of solid industrial waste and municipal waste produced from many purposes. It is essential to meet the goals of sustainable development which it is a plan for a better and more sustainable future for all. These goals address the global challenges we face, including the challenges of environmental degradation and prosperity. It is important to achieve goals of Egypt’s vision 2030, to provide a safe and sustainable environment for future generations through the implementation of development policies and capable of stopping the degradation of the environment. The main purpose of this project is to reduce the density of textile solid waste generation and to raise the efficiency of water productivity through eco-friendly, environmentally, safely, economically, and scientific disposal of fiber waste, and glass waste. All of which will be applied for wastewater treatment. As well the use of non-conventional methods in the treatment of water to obtain water for drinking or agriculture or for other purposes will be applied as follows: • The use of fabric waste for the production of flat membranes and also the preparation of photo catalysts for the treatment of wastewater. • The necessary characterization and tests will be carried out on the prepared membranes and photo catalysts.      

Agricultural and industrial wastes (AIWs) have pulled a lot of attention because of their significant environmental, economic, and social impacts. Waste recycling into high-value products is of particular importance. In this context, AIWs have been considered a crucial link of a closed loop for the fabrication of nanomaterials (NMs) and composites wherein they replace traditional resources with sustainable waste in waste management. One of the major problems in the 21st century is the continued energy demand. This report aims to investigate the technical feasibility of using innovative AIW resources and various strategies for the fabrication of carbon-based NMs for improving energy storage and conversion applications. First, the utilization of AIWs is classified comprehensively. Second, key technologies of the production of carbon-based NMs are reviewed. Third, the potential of fabricated carbon-based NMs in energy storage and energy conversion are investigated. We discussed the energy storage potential of these materials in detail by reviewing the most recent literature available regarding batteries and supercapacitors. In addition, we highlighted the promising applicability of waste recycled carbon-based NMs in energy conversion applications by summarizing three different forms in which they are applied: fuel cells, solar cells, and photocatalysis. Finally, conclusions and future perspectives are presented.
