給同事的電郵,幫忙一下要英文

It has come to our attention that some waste items were found in the back alley (corridor) of the rear door.[假如是在公司內的走廊，如果是公眾的走火通道可以改用fire escape lobby outside the rear door.]

Please take note to handle rubbish disposal properly and do not leave unused items in the passageway.

[你都算有心機使用不同的字眼，不過未識用英文作文，只係把中文變成英文字。好好努力看多些政府或一些品質好的管理公司通告，可能會幫助你處理其他不同的情況。]

您好，我推薦您一個非常不錯的英語學習網站，里面有很多非常不錯的學習資源，您能從中得到不少幫助：

可以這樣寫：

As the recent finding of a number of discards disposed at the corridor nearby the back door, please help to advise the other colleagues do not place any discard there and to suggest the proper way for disposing the garbages.

As the recent discovery of a number of off-site disposal at the door the corridor, please help to my colleagues say this not to place articles and recommended way to dispose of garbage properly.
