Is Waste Management a sector with growth potential?

My thought process was that there is and will always be demand for waste management, waste processing, waste recycling. Is this sector in fact cyclical, opposite to my understanding of the sector? Is it a sector that is considered future-proof and worth investing in? Is my thought process wrong? How does the market view the waste management sector? I have a small share of my portfolio in the sector but the movements recently have rather been disappointing I would say. I had significant profits a few months ago, but recently it's been going down. I'm personally not aware that the waste management sector works in cycles like other sectors do, so that's why I held and holding onto my waste management segment within my portfolio, currently 4-5 positions, other 2 I had usually in the rotation as well. Do you have waste management sector in your portfolio? Are you holding, buying or selling? Looking forward to your insights! Thanks in advance!
