When you finish that bottle of lawn treatment you could recycle it....or
Wash it out dry it and keep your grass seed in there. The yellow spout gives a good spray scatter to the
fertilser - just as good for grass seed, or maybe salt to keep your paths ice free this winter.
Consider that in raw materials and energy, it takes 1.75 kilograms of petroleum to make 1 kilogram of HDPE.
Refill please :)
