Is the Coke bottle worth the money?

Is it worthwhile to save energy and reduce emissions in the cola bottle of garbage classification?
Waste products are sold and made on Saturday, and energy conservation and emission reduction are supported.
Calculate the benefit cost:
The waste revenue of a large cola bottle is 0.1 yuan (0.05 yuan or 0.1 yuan) (S1) yuan, with a base area of about 0.01 (S2) square meters, which is sold once a month on average, house Price: RMB 5000 (X)/square meter,
Average investment income: 4% (y)/year (deposit interest: 2%, mortgage: 4% ~ 6%, gdp8 %); 15 + 10/3 .24 + 10/7 .1 = 20

The 70-year income of the cola bottle is 20 yuan, and the cost is 50 Yuan. If the labor cost is not calculated, it is already at a loss.
The average investment income is 0% (y)/year. The annual income of selling a big cola bottle for 70 years is 0.1*12*70 = 84 RMB, and the cost is 50 RMB.
Labor cost calculation: Income is not equal to Labor Cost
The monthly income is RMB 700/month. waste is collected once every February. It takes more than 15 minutes to collect waste products. The labor cost is RMB 1, which does not cover the income from waste products (reluctant to drink cola, no waste paper );
In other income groups, the waste products are large, but the labor cost is higher.
My family gave the job to a child, and his income also exists, but the child is not active.
My family can only sell one or two yuan at a time, and all kinds of bottles, paper and shells also disrupt the family environment.
Conclusion: when there is no waste storage area in the residential area, the waste (cola bottle) model is almost impossible.
SIGHS: I think of the old man who turned the garbage and looked at me when I lost a Coke bottle a few years ago...
