宜蘭地區垃圾燃燒後的飛灰殘餘，透過穩定固化處理，目前都謹慎地堆放在沙丘背後的儲存場地。近年縣政府決定將露天開放式的飛灰掩埋場改進為倉儲披覆式，以降低汙染環境的可能性。
倉儲基地與焚化爐位在利澤工業區，多年前這裡也曾是多脊沙丘。設計將縣政府初步規劃的掩埋區轉九十度與海岸沙丘方向平行，讓過去保護蘭陽平原不被海嘯侵襲的沙丘，透過掩埋區的堆置設計一道一道「長」回來。
倉儲廠像是抽象的局部沙丘，大頂棚的支撐利用組合的角鋼取代慣用的H型鋼，組構成大跨距的桶狀超大空間；南北側的混凝土牆是曲折錯落的型抗結構，拆模後形成自然的崩角，配合錯落有機的紋理與陰影，像是海岸沙丘上自然崩落的沙丘斷面。倉儲廠的任務是階段性的，盡可能用較少的物質和可拆解回收的材料，讓基地保留未來的彈性。
隨著時間推演，儲存進暫存場的固化物，在空間滿載前，將利用非雨季的時間，搬運至倉儲廠西側的掩埋區。掩埋區為了減少混凝土的使用，以特殊的不透水HDPE布，像包包子一樣將飛灰固化物堆成金字塔狀的單元封存。透過謹慎地監測與看顧，避免污染到土地與地下水；同時也保有未來取出固化物再利用的可能性。掩埋區的堆放過程設計了堆置的秩序，邀請植被與活動進入。隨著每一年不同的變化，地形、植栽和新的故事將順著古地圖中記載的溪南多道沙丘以及史詩般的海岸地景一起成長。化危機為轉機，這裡將是可以真實體驗的大尺度環境教室，讓來訪的每個人思考廢棄物處理與資源再生的永續問題。
The fly ash wastes produced by incineration in Yilan undergo a process of solidification and are placed carefully in the storage arenas behind nearby dunes. In recent years, the government decided to move the fly ash from open landfills to covered warehouses, reducing the possibilities of environmental contamination.
The project site and the incinerator are located within the Lize Industrial Area. This area was once covered by multiple layers of dunes. The proposed design turned the original planned landfill 90 degrees, making it parallel with the seaside dunes. Using a designed sequence of stacking, layer and layers of dunes will “grow” back to protect the Lanyang Plain from tsunami.
The Storage Warehouse was conceived as an abstract sand dune. The roof is supported by a combination of steel angles, instead of commonly used “H” beams, to form a long span mega space. The zigzag concrete walls on the north and south sides form resistant structures. During the removal of formwork, parts of the concrete will fall off. The texture and shades of raw concrete look like a cross section of a naturally collapsed sand dune. The warehouse provides temporary storage for the solidified ash, so the construction material used are minimal and recyclable. This allows the site to be use flexibly in the future.
Before the storage warehouse reach full capacity, the solidified ashes will be transported to the landfill west of the warehouse during the non-rainy season. In order to reduce the use of concrete in the newly designed landfill, impervious HDPE blankets are used to mold the solidified ash into pyramid-shaped units. Sewage pipelines are installed at the bottom of the landfill to intercept possible pollution seepage in order to avoid contaminating the land and groundwater with careful monitoring. This also allows for the removal of the solidified material for reuse in the future. The landfill storage sequence is designed to allow vegetation and human activities to enter. With changes every year, the terrain and the vegetation will grow with the coastal landscape. They are like the multiple layers of sand dunes recorded on ancient map creating fresh stories. By turning an environmental crisis into a design opportunity, the project becomes a large scale environmental classroom encouraging visitors to reflect on sustainability issues like waste treatment and recycling.
