What is the temperature required to form vermicompost?
It depends on the different conditions of compost production. Still, usually, the appropriate temperature for the maximum activity of worms in the vermicompost production process is 35 degrees Celsius, but this varies depending on the type of compost because, for example, in the process of thermophilic compost production, the temperature may be between 60 and 70 degrees. Usually, after preparing the bed with the appropriate temperature, the creams are placed on the production bed.
What are the types of worms active in the formation of the vermicompost process?
Eisenia foetida, Lumbricus rubellus
Generally, the above two species are used to produce vermicompost. Reproduction of these species in the production medium is very suitable, and the culture medium is a more suitable environment for the reproduction of these two species.
What are the most important environmental benefits of vermicompost?
Vermicompost improves soil structure, texture, porosity, water holding capacity, drainage, and aeration and reduces erosion. Moreover, vermicompost enhances plant blooming, suppresses plant diseases, increases porosity and microbial activity in the soil, and improves water retention and aeration. In addition, vermicompost helps improve plant growth by enabling the development of new shoots and leaves, thereby increasing productivity. It helps to neutralize the pH of the soil. Vermicompost also benefits the environment by reducing the need for chemical fertilizers and decreasing the amount of waste going to landfills.
What are the most important economic benefits of vermicompost production?
Vermicompost production can be an "economically productive" process because it reduces a large amount of food waste, contributing to sustainable agriculture and organic production. Vermicompost production is an effective process in reducing recycling and waste collection costs and saving landfill space.
What can be the role of the circular economy in the food production industry?
Circular food economics uses the natural cycles of materials produced and consumed. The routine is that the waste generated at the end of the cycle is cleaned through biological processes and instead used as a raw material for the production cycle of new natural products. The organic product is obtained from food by-products, is free of contaminants, and can be returned to the soil through an organic process.
How can a circular economy pave the way for sustainable development?
The circular economy in sustainable development can be understood as a sustainable economic system. One of the essential features is that it can be considered economic growth through the reduction and re-circulation of natural resources consumables. It is a kind of use of resources and its revival. The main goal of this approach is to maintain the natural cycle of recycling, products, materials, and resources to reduce waste in nature. This will lead to less extraction of natural resources and reuse of a product in different forms. One of the essential advantages of this system is that optimization and productivity are formed to reduce raw materials, and finally, we will have sustainable development based on sustainable growth.
What are the most important challenges of the circular economy?
Some materials fit more easily into the circular economy than others. Nearly all food and drinks cans and other steel packaging, for example, are recycled. But some materials present a much tougher challenge. (Source)
How can a circular economy in the digital context contribute to sustainable development?
At the same time, there are two ongoing transitions: the creation of a circular economy and the digital transformation that could provide the means to address these challenges, if they are managed well. (Source)
What are the most important environmental benefits of a circular economy?
Moving towards a more circular economy could deliver benefits such as reducing pressure on the environment, improving the security of the supply of raw materials, increasing competitiveness, stimulating innovation, boosting economic growth (an additional 0.5% of gross domestic product), creating jobs (700,000 jobs in the EU alone by 2030).

According to statistics, what is the amount of food waste in the EU?
In the EU, around 88 million tonnes of food waste are generated annually with associated costs estimated at 143 billion euros (FUSIONS, 2016). While an estimated 20% of the total food produced is lost or wasted, 33 million people cannot afford a quality meal every second day (Eurostat, 2018). (Source)
What is the difference between food waste and food loss?
Food Loss is that gets slopped, corrupted or otherwise lost, or incurs lessening of quality and value during its process in the food supply chain before it gets its final product phase. Food loss commonly takes place at production, post-harvest, processing, and distribution stages in the food supply chain. Food waste refers to food that is fit for consumption but purposefully abandoned at the retail or consumption stages.
How is food waste measured in a restaurant?
Industry leaders have agreed there are three principles of food waste measurement: (1) Food waste measurement and reduction should focus on farm to fork in pursuit of SDG Target 12.3. (2) The framework of the Target, Measure, Act represents the best way to make progress on food waste measurement and prevention. (3) Consistent definitions of food, food waste, and inedible parts, must be adopted by every organization which commits to measuring and reducing food waste. (Source)
What is the possible ways to manage food waste at home?
(1) Planning meals and shopping smartly. (2) Storing and saving food properly. (3) Organizing the fridge and pantry. (4) Memorizing expiration dates. (5) Eating the leftovers. (6) Getting creative with scraps. (7) Starting a composting process. (8) Donating to food banks.
What are the important effects of increasing food waste on the economy?
The bottom line is that wasted food is an environmental concern. Food wastage is observed in all stages of production up to the supply of goods and consumers. When we waste food, we also waste the energy and resources needed to grow, harvest, transport, and package. And the resulting loss leads to increased levels of methane and greenhouse gases, especially carbon dioxide. On the other hand, if we add the costs of food waste, we will see a decrease in profits, an increase in commodity prices, and a decrease in production in the economy. Secondary economic effects can reduce productivity, and food insecurity, increase commodity maintenance costs and ultimately reduce the productive force in economic production.
What are the most important ways to avoid food waste?
(1) Reducing Stage: Using less of or doing without unneeded components and cooking fewer pieces to avoid extreme scraps. (2) Reusing Stage: Repurposing food leftovers instead of tossing them out and using reusable receptacles to purchase foods in proportions. (3) Recycling Stage: Composting portion food wastes.
What are the innovative solutions to reduce food waste?
Shelf-life extension technologies reduce food waste at the consumption stage by allowing perishable foods to last longer. Some examples are: (1) Making garbage optional (2) Fruit natural coating (3) Online Marketplace from farm to home directly (4) Smart diverse fruit boxes (5) Getting wasted food off the shelves (6) Getting food off the shelves (8) Getting food off the shelves
How can reducing food waste contribute to sustainable development?
SDG 12.3: "By 2030, halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses." Reducing food waste provides multifaceted gains for people, the planet, and prosperity. It improves food security, addresses the global problems of climate change, biodiversity loss, and pollution, and reduces the burden on waste management systems. The UN Sustainable Development Goals (SDG) aim to halve food waste by 2030. (Source)
How does food waste produce methane?
