Description and Codes
Recoded Variables: Waste segregation at source, type or location of waste
collection and mode of payment
Level 1: segregation required, modified pick-up and pay as you throw
WTL1 = 1; WTL2 = 0 (dummy codes)
Level 2: segregation not required, modified pick-up and pay as you throw;
WTL1 = 0; WTL2 = 1
Level 3: segregation not required, curbside and pay to the barangay
treasurer; WTL1 = 0; WTL2 = 0
Socio-Economic Variables Interacted with Attributes
Environmental Knowledge, Attitudes and Perceptions:
Summation of scores from A1, A2, A3, and A4; divided by total number of
items
If respondent’s household practices recycling or re-use of waste materials
Yes = 1 Otherwise = 0
If respondent’s household practices composting
Yes = 1 Otherwise = 0
Estimated biodegradable waste disposed by the respondent’s HH, in kg
Estimated non-biodegradable, residual waste disposed by the respondent’s
HH, in kg
Presence of Indigenous Beliefs on Solid Waste Management
x WTL2 Yes = 1 Otherwise = 0
7. EDUC x P Years of formal schooling
8. GENDER x P Gender of respondent ; Male = 1 Female = 0
9. HHSIZE x P Number of HH members
10. DECI x P If respondent is sole decision maker Yes = 1 Otherwise = 0
11. HHINC x Total Household Income
12. HOUSE x F Ownership of house; Yes= 1 Otherwise = 0
x P
13. ROOMS x P Number of rooms in the house (if owner of house)
14. ASSETS x P No. of assets, e.g., house appliances, vehicles
15. LAND x F Ownership of land; Yes= 1 Otherwise = 0

3.2.2 Ecological Solid Waste Management (ECOSWAM) Services
Preferences of Business Establishments
3.2.2.1. Attributes and Levels of the Proposed ECOSWAM Services for
Business Establishments
The attributes and levels of the proposed ECOSWAM services for business
establishments are similar to those of the households except that the garbage fee is per
sack (volume) and that the type and location of waste collection is modified pick-up.
Since the latter attribute is the same for all business establishments, this was no longer
included among the alternative specific attributes.
