Metro Cebu is the largest urban area in the Visayas and considered as an important technology hub to serve the southern part of the Philippines. This is underlined by the presence of export processing zones, numerous call centers and booming IT sectors. Metro Cebu includes the component cities Mandaue, Lapu-Lapu, Cebu and Talisay. With a total population of around 1.6 Mio inhabitants in these 4 cities, the amount of potential e-waste generation from the households is not known at the moment. Up to date, there is no state of the art recycling facility for EWM established in Metro Cebu to handle the growing volume of e-waste.

RESULTS AND DISCUSSION Based on this survey a significant high E-waste generation potential of 34,600 tons/year is estimated for Metro Cebu alone from households, which translates to 95 tons/day respectively 21.6 kg/cap/year. The result of the survey also showed that households generally tend to dump materials if reuse or recycling options are not available as a common mode of solid waste management. So far, E-waste is regarded as Special Waste in most LGUs and hence regarded as a minor waste fraction of far less than 1,200 US-$ [2]. For the households, it was assumed that various equipments are ubiquitous such as small and large household appliances, television sets and computers, telecommunication equipment, electronic tools, lighting equipment, electronic goods for entertainment, toys and leisure, medical devices, monitoring and control instruments and automatic dispensers. Available official information from various governmental agencies that regulate imports and exports, such as the Bureau of Customs (BOC), the Environmental Management Bureau (EMB) and the National Statistics Office (NSO), were also utilized during the survey.

To support this process, further research should be conducted by local academe to develop needed monitoring tools and to support joint learning for involved stakeholders. Results of the E-Waste Assessment of various household groups in Metro Cebu, 2010 * Average household size for all household categories is 5.1
