In August 2005, the 10-Year SWM Plan was finalized and submitted to the DENR-EMB 6/NSWMC for approval. Since most of the waste is organic, a MRF for biodegradable materials was established in November 2005, which is called the Dunang Manggad compost demonstration center using vermicomposting technology. Since then, the center has trained already about 2,000 farmers, 1,000 students and 36 barangays on organic farming and application of the vermi-composting technology.
In December 26, 2007, the municipality enacted its Municipal Ordinance No. 194-2007 on the Comprehensive Ecological SWM Ordinance. The following year, the municipality organized the Barangay Ecological SWM Committees through Executive Order 03-2008, and at the same time, reactivated its Municipal SWM Board through E.O. 14-2008.
With support from GIZ/AHT SWM4LGUs, an updated Waste Analysis and Characterization Study (WACS) was conducted in July 2008 in urban barangays of the municipality (Please see Table). The average waste generation rate is 0.36 kg/capita/day and as per census 2007, the estimated waste generation is 17 tons/day.
The existing collection system covers 7 urban, and 3 rural barangays out of 36 barangays. The collection rate is only 20% out of the 17 tons per day waste generation. The municipal government utilizes 1 garbage truck of 4.0 tons capacity with specific route. Garbage collection is done 2 times daily including Saturdays and Sundays.
The municipality submitted a Closure and Rehabilitation Plan for its existing 1.75-hectare controlled dumpsite at Sitio Kalalan, Brgy. Piña and was granted an Authority to Close (ATC) in June 2006 by EMB-Region 6. The controlled disposal facility (CDF) is still utilized by the municipality for its waste disposal but recommended measures stipulated in the ATC are being followed.
The LGU is again updating its 10-Year SWM Plan based on NSWMC's annotated outline. The planning for strategies to enhance the municipality’s SWM system and to fully implement its SWM Ordinance and other related ordinances are continuously pursued.
Material Resources Recovery, Recycling and Composting. The recycling activities of 10 junkshop owners in the municipality and the informal sector, especially the women recyclers, are recognized by the municipality and partly integrated into the waste management system since they have also significantly contributed to an increased waste diversion rate.
The WACS 2008 revealed that 72% of the municipal solid waste is biodegradable, Since the present collection covers only 20%, households from rural barangays were trained on composting. Farmers also from rural barangays were organized into informal associations and they conduct their own composting of agricultural waste.
Bio waste from the urban center and market are composted at the Dunang Manggad compost demonstration center.
Dumpsite Closure and Rehabilitation. The current controlled disposal facility located at Brgy. Piña (10° 39' 03” N Latitude and 122° 38' 59” E Longitude) will be in operation until such time the common sanitary landfill (SLF) for the Province of Guimaras is established.
Sanitary Landfill Establishment. Presently, the Municipality of Buenavista had already acquired a 4-hectare lot at Sitio Kalalan, Brgy. Piña for its proposed sanitary landfill (10° 39' 10.2” North Latitude and 122° 39' 02.0” East Longitude). However, in order to complement with the present strategy of the Province of Guimaras for a common SLF for the whole Guimaras province, the identified SLF site of the municipality is proposed as the Municipal Eco-Waste Processing Center that will include material recovery facility, composting area, office/training center and temporary residual and special/hospital wastes containment area.
