This blog explains how Wet Umbrella calculates the plastic bag waste saved by using Wet Umbrella Dryers when compared with Wet Umbrella Bagging Machine. It is intended for clients who need to estimate bag savings for both cost reduction and waste prevention. The calculation shows how much waste each machine can prevent when using one microfiber pad per day. Additional capacity can be achieved by keeping extra microfiber pads on hand, which may be helpful where storage space is limited by machine size. For example, a machine with capacity for 2,000 wet umbrellas can handle up to 4,000 wet umbrellas per day with one additional pad, provided the microfiber pad is changed during the day.
For Extra Large, WUDA-1100, WUDAPR-1100, WUDAWF-1100.
Assume one out of five has wet umbrella to dry, for any day over 5mm of rain estimation of 30 days per year (check your local annual rainfall).
10000 wet umbrellas per day, can cover up to 50000 in foot traffic.
This is 10 boxes of 1000 bags saved at 3kg each.
30kg of bags per day x 30 days.
900 Kg of bags or HDPE. The bags will expand and take up a lot of space. Also, if recycled not all can be recycled. Biodegradable is there microplastic waste involved?
For  Large, WUDA-900, WUDAPR-900, WUDAWF-900.
Assume one out of five has wet umbrella to dry, for any day over 5mm of rain estimation of 30 days per year (check your local annual rainfall).
5000 wet umbrellas per day, can cover up to 25000 in foot traffic.
This is 5 boxes of 1000 bags saved at 3kg each.
15kg of bags per day x 30 days.
450 Kg of bags or HDPE. The bags will expand and take up a lot of space. Also, if recycled not all can be recycled. Biodegradable is there microplastic waste involved?
For Medium, WUDA-500, WUDAPR-500, WUDAWF-500.
Assume one out of five has wet umbrella to dry, for any day over 5mm of rain estimation of 30 days per year (check your local annual rainfall).
