“circular Economy And Energy Recovery From Waste In Europe” – The demand for carbon neutral solutions now dominates the energy sector and a host of other industries, so adopting technologies that use waste resources is an important step in the right direction.
Circular energy systems – those that reuse and recycle resources – can increase energy efficiency and reduce carbon footprints. They do this using tools like carbon capture, utilization and storage (CCUS).

The 7-megawatt power plant is powered by wooden beams made from local waste wood. These will release the equivalent CO that is naturally stored
Emissions are separated from the greenhouse gases of the equipment and use. The compact system from the Mitsubishi Heavy Industries Group (MHI) uses a high-efficiency KS-1 amine material to handle emissions.
The system’s modular design minimizes investment, operational and maintenance costs and allows rapid delivery, making it much easier to install than large bespoke containment systems.
From the plant in horticulture, to grow crops on a large scale. There are also many other applications, ranging from cement production to the chemical industry
Basics Of Circular Economy
Bioenergy with carbon dioxide capture and utilization systems like the one in Hiroshima can provide a starting point to support efforts to decarbonize by increasing the area’s size, energy efficiency and heat generation.
Plants like this use local waste materials like wood or agricultural residue as feedstock, which offer clear environmental benefits. Bioenergy does not add CO
Released during energy production with such fuels comes from carbon that is dispersed naturally in the atmosphere through photosynthesis and decomposition.
Emission is the source when energy is generated, and safely store it. A negative emission results if the amount of CO2 stored is greater than the level emitted during the production, transportation, conversion and utilization of bioenergy.
Closing The Loop On The Circular Economy
Local waste wood can be chipped and used as biomass with CCUS to help power a sector economy
While the business case for CCUS has not been proven, scaling technologies should bring down costs and make it more feasible, in the same way that wind and solar costs have fallen in recent years.
But for energy producers and other heavy industries, adopting technology that enhances the energy cycle has economic and environmental benefits. It reduces both costs and electricity consumption and generates additional revenue from selling surplus energy back to the grid.
The real winner, though, is life. As the race to reach net zero accelerates, the ability for the energy sector to focus on negative emissions can make a significant contribution to combating the threats of climate change.
Sustainable Finance For A Zero Waste Circular Economy
Johnny Wood has been a journalist for 15 years working in different parts of the world – Asia, Europe and the Middle East. It specializes in energy transformation, sustainability and innovation. The shared economy aims to reduce the generation of waste and to maintain the value of products, materials and equipment as long as possible in the economy. The transition from a linear to a decentralized economy Chemical (petro) industries in Europe already have a proven track record of strategic commitment (conserve and improve capital, improve resource yields and system effectiveness) as an important pillar of its business models. Cost control is the key to compete in global markets. This drive, along with the environmental benefits of the circular economy, explains why petrochemical producers in Europe see such an advantage in these efficiency steps.
In March 2020, the European Commission adopted a new Environmental Economic Action Plan – one of the main building blocks of the European Green Deal.
A new Action Plan announces initiatives throughout the life cycle of products, aiming to exemplify their design, promote shared economy processes, foster sustainable energy, and aim to ensure that the resources used are we keep in the EU economy as long as possible.
The chemical industry is calling for the right conditions to develop these solutions in Europe with the European Single Market for Waste, and better access to public and private funding for innovative technologies. The chemical industry is committed to further advancing this technology through research and development efforts. We also believe that actions by the Circular Plastic Alliance platform and similar initiatives will create a more dynamic market for recycled plastic, which will also increase demand in chemical recycling. This is why it is important for chemical recycling to remain part of the EU’s recycling program and benefit from Green Recovery investments.

Petrochemicals also enables the resource efficiency of downstream user companies as other consumers, for example by providing essential building blocks for waste reduction (through thin packaging material such as foils), increasing energy efficiency (for example through insulation material ), reducing emissions (through renewable energy devices such as solar panels and wind blades) and fuel consumption (through additives), or improving the convenience of everyday products (for example lightweight plastics instead of heavy components).
Petrochemicals also act as facilitators for the distribution economy driving resource efficiency of downstream user companies as other consumers, for example by providing essential building blocks for waste reduction (through thin packaging materials such as foils ), increasing energy efficiency (for example. through insulation material), reducing emissions (through renewable energy devices like solar panels and wind blades) and fuel consumption (through additives), or improving the convenience of everyday products ( for example lightweight plastics instead of heavy components).How can heat treatment of waste help keep material in the loop? Contrary to popular belief, Waste-to-Energy actively participates in the sharing economy.
In order to be fully sustainable, we have to truly address waste challenges. The ultimate solution is reducing waste at the source, meaning less waste production. However, until we reach that point, it is important to stop the stocks, in the circular cycle before they are lost forever.
Improving and increasing recycling, sorting, and recycling processes will play an important role in improving the sharing economy. However, some remaining waste streams, requiring safe treatment, will persist and may grow worldwide. Even with the best technologies available, recycling will not always be feasible or economically viable for certain wastes. The only seamy method for treating waste of this size is in waste-of-can-waste plants, which press the flow of particles.

Waste-to-Energy offers a comprehensive approach to recovering resources from non-recyclable, non-hazardous waste; it diverts those wastes from landfills, recovers metals and minerals, and produces renewable energy (from the fraction of waste that is non-hazardous), thus becoming an indispensable link of the economy sharing and creating value for society.
Waste-to-Energy plants can recover materials from incinerated bottom ash, including composites, minerals, ferrous and non-ferrous metals (copper, aluminum, zinc) and even precious metals, such as silver and gold.
These materials are also injected into the shared economy with useful and necessary materials. They are truly important to the green and digital transition in Europe as metals are key components in electronics. For example, laptops and smartphones, batteries, solar panels, and wind turbines. Therefore, materials recovered from bottom ash incineration also contribute to avoiding energy-intensive extraction and processing of virgin materials.
Bottom ash is also well suited for construction and can be used as aggregate for foundation layers, for example in roads or parking areas. It can also be used for bridges and sound walls, or in concrete products such as bricks and kerbstones. Many European countries use bottom ash as an alternative to virgin material such as gravel and sand.

By treating non-recyclable waste, Waste-to-Energy plants can generate energy in the form of steam, electricity or hot water.
This energy, known as partial renewables, contributes to the transition away from fossil fuels in electricity, district heating systems, power plants and the transportation sector. In 2019 in Europe, Waste-to-Energy plants produced 43 billion kWh of electricity, which provided 20 million citizens with electricity.
One of the main advantages of energy produced from waste is that it is not subject to price changes of raw materials and fuel, nor is it vulnerable to relative supply problems. In the context of increasing energy prices, energy from waste is financially stable. Furthermore, energy from waste is a secure basic energy giving flexibility and stability to the power grid, due to its complementary effect to central renewable energy sources.
The production of energy from non-recyclable waste is classified, including the generation of renewable and low-carbon hydrogen and synthetic fuels, which are important in reaching the climate goals and the renewable energy goals set .

Waste-to-Hydrogen has many uses. For example, in the production of ammonia and in transport, where you can decarbonise heavy transport by powering, among others, fuel cell buses and build trucks collecting urban waste. A specific example already exists in Wuppertal, Germany where Waste-to-Hydrogen powers 20 public transport buses. It has been estimated that the city of Wuppertal already saves more than 700 tons of CO
The use of carbon capture for utilization or storage (CCUS) technologies in WtE facilities has the potential to reduce the carbon footprint of the sector, while also being another way in which the sector contributes to the Environmental Economy.
Carbon produced from WtE operations can be used in chemical products and plastics, for example windows and others
