The global economy requires a large and uninterrupted flow of energy daily. In the context of the gradual depletion of non-renewable resources, I propose a new landscape form - the energy production park. At the same time, this landscape form is becoming more critical within the global energy crisis exacerbated by the conflict between Russia and Ukraine. The international price of natural gas is soaring, and the price increase will hit lower and middle-class families hard. The idea is based on the site's history, the poverty level in Croydon, and a response to the reuse of abandoned resources and land within site. The ultimate goal is to continue providing energy for the community and the park and suitable habitats for people and wildlife. I have proposed different landscape elements, such as biofuel farms and algae ponds. In the design, I divided the site into three main areas: wetland, landfill, and algae farms. The combination of wastewater treatment and algae farming could amplify energy production, while clean water could be used for wetland water and urban water supply. At the same time, the landscape could offset Carbon emissions. Landfill areas are transformed into water storage wetlands and future fuel farms. The potential leachate from the waste could accelerate the growth of algae and fuel crops and clean up landfill pollution through Thesevegetation.three designs are integrated through the design of the water system. In summary, the project envisages the development of a consistent alternative landscape energy approach for the site, building on existing renewable energy sources and through larger-scale bioenergy recovery, simultaneously promoting an ecological corridor within the Wandle Valley. The project has the potential to help tackle climate change, responding to the call for 'Croydon City Council to declare a climate emergency. At the same time, it aims to create a biodiversity park for wildlife, particularly birds, and to increase public participation.

The industrial area is on the east side of the site. The local access from west side. And there are 4 large structures (power towers) on the site.
The plant is pumping out three times as much CO2 as other, similar facilities. Because of too much greenhouse gas produced by the incinerator, many passive voices has opposed the development. Dark Jungle Area
There are two reasons for the high level of contamination of the site. One is due to the discharge of wastewater from the industrial area into the site, and also the erosion of the soil by the landfill itself. Those two reasons lead to severe soil contamination on the site. And it ultimately affected water quality.

The Sewage Ponds
The restoration of the landfill site is not well done. There is still a lot of rubbish on the surface that has not been removed. It is easy for birds to accidentally eat it leading to death. Many landfill sites are not publicly available to Viridor and information on the protection measures below is not known. However, judging from the sharp decline in bird numbers, there is possibilities that landfill leachate seepage might leads wetland water pollution.
Industrial area Power tower Power tower Residential area Residential area
The landfill site occupies an area of 42.84 hectares. The landfill is generating electricity from biogas. The huge waste is covered with a shallow green area. And a large number of oak trees have been cut down around the site to make way for underground water pipes.
The site is inhabited by a large number of birds, but the number of bird species is decreasing every year. This site used to attract many birdwatchers and has several existing bird watching points. Fense The company has fenced off the site, making it impossible for people to get a closer look or get close to the site. The company does not want people to enter the site because of the high level of contamination on the site.
"Alfrey says he has no doubts that some of the activity in the area has broken wildlife and planning laws, in an effort to degrade the habitat and therefore make justification for the land’s development all the easier" (Insidecroydon, 2019).

There are many jungle-dense grey spaces along the side roads. The neighbourhood has a high crime rate and the bush spaces are more likely to increase crime. Bird Watching Point
The current state of the site has different functions. But most of the sites are off-limits to people. Beddington Sewage farm was once an important habitat for birds and the site is now used for industrial units. Because the site is huge, so on this page I have combined all the analysis with photos. The story of beddington will be told more clearly.
Understanding the current water system of the site is important for the design. The current water systems on sites are not circulating and some sites are prone to stagnant water, which might leads to odours and reduced biodiversity.

Water level seasonal change The Beddington farmland has seasonal water level changes. This can provide a variety of habitats for birds. But Viridor deliberately destroys the ecology of the wetland (by not releasing the water when the water level is too low, causing the birds to be eaten by other animals) to create the illusion of ecological collapse.

There are also seasonal variations in water quality in the older sewage ponds. From June to September, the entire sewage ponds are subject to a massive growth of algae. This is not only unsightly but also causes a bad smell. Wetland lake The negative impact of landfill and sewage ponds on wetlands (bird habitats) is significant in certain seasons. Birds simultaneously spread the algae brought in from sewage ponds. It might lead to a massive algal bloom in the wetlands. -0.9m -1.1m -3.3m

The flue gases may contain particulate matter, heavy metals, dioxins, furans, sulfur dioxide, and hydrochloric acid. Biogas collection system mainly can produce energy like methane. But in the meantime, a fraction of the methane in the gas is oxidized microbially to CO2

* Using landfill-generated energy to power the site and addressing soil issues through sustainable landscaping measures such as fertiliser from algae farms.
SOLUTION 2 * LANDFILL CLEANING
* In exchange for sufficient funding for the pre-park study, viridor could negotiate with the government for roughly 10 years of use of the power plant.
Essential funding requirements for this project include algae research and the construction of primary roads. However, the design of this project respects the original topography and function of the Beddington farmland. The cost of the project is, therefore, meagre. At the same time, the use of recyclable construction materials, taking advantage of the site's characteristics, has resulted in cost savings. The primary maintenance of the site relies on Viridor's self-monitoring and volunteer supervision.
These are the companies that may sponsor beddington energy park. They are all environmentally and eco-friendly companies and are committed to creating a green wandle valley area.

Algae farms and biofuel farms are also starting to bring biodiversity to the site and provide habitat for different bird species. Biodiversity is already thriving at this stage in the Bioenergy Park.
After the success of the Beddington bioenergy park, elements of the energy Wandlegraduallylandscapespreadtovalleyahundred years later. Algae farms are located close to the industrial area and rely on chemical gases produced by the factory. At the same time, the wastewater is purified by the algae farm and provides water for the biofuel farm. Biodiversity has increased significantly in the wandle valley through ecological corridors.
People can only visit 2 bird watching sites, there is no extra programme for people to play or view, except walking along the road.
In the first phase of the park, the green areas of the park are transformed into different functions, such as, playground and plaza.

When the algae season comes, the reeds will be harvested and transported to the wetlands to be used as nesting material (floating islands) for the birds.
Microalgae culture offers tertiary biological treatment and the production of potentially valuable biomass. Because of their ability, microalgae cultures provide an elegant solution for tertiary and quaternary treatment using inorganic nitrogen and phosphorus to promote their growth. And because of their ability to remove heavy metals and some toxic organic compounds, algal farms can prevent secondary pollution.

EXPANSION STRATEGIES. Furture growth (100 years later)
There are certain particularities in the choice of locations to create energy landscapes. Algae farms are selected near industrial areas and rivers, which ensure a large amount of carbon dioxide for algae growth. At the same time, there is a water supply. Algae farms can purify water for re-discharge into rivers or provide water for biocrop farms to grow plants.
