英國開放大學（The Open University，簡稱OU）是一所公立研究型大學，也是國際知名的遠程教育大學。OU大學的環(huán)境、地球和生態(tài)系統(tǒng)科學學院擁有7套獨立的16通道SSI模塊式堆肥/土壤呼吸測定系統(tǒng)（相關鏈接參見https://www.open.ac.uk/stem/environment-earth-ecosystem-sciences/research/analytical-facilities/ecosystems-laboratories）, 可處理和分析一系列環(huán)境材料，包括土壤、水、大氣氣體、植物、堆肥和可生物降解廢物等。       該高通量土壤呼吸測定系統(tǒng)允許在特定環(huán)境條件下(如處理溫度和曝氣)在線記錄和測定二氧化碳、氧氣和甲烷。作為歐洲領先的呼吸測量設施之一，用于研究廢物和塑料材料的生物降解性測定（例如：用于機械分揀生物處理（Mechanical Biological Treatment，MBT）評估的持續(xù)4天動態(tài)呼吸（Dynamic respiration over 4 days,DR4）測試，堆肥質(zhì)量標準PAS100穩(wěn)定性測試，用于塑料的BS14855生物降解標準等）。       180天后，纖維素的降解率為100%，PVOH的降解率為7%。結(jié)果表明，在模擬工業(yè)堆肥條件下，本實驗所測試的PVOH薄膜材料不能進行生物降解。
