The typical uses of Low Density Polyethylene (LDPE) are the following:(I) Food wrapping (II) Trash bag (III) Grocery bag (IV)diaper

I, II, III
I and IV
I, II, III, IV
II, III, IV

Correct Answer

A. II, III, IV

Explanation

The correct answer is II, III, IV. LDPE is commonly used for trash bags, grocery bags, and diapers. These products require a material that is flexible, durable, and resistant to tearing, which are properties of LDPE. LDPE is also safe for food contact, making it suitable for food wrapping. Therefore, options II, III, and IV are the correct choices as they include all the typical uses of LDPE.

The feasible options for achieving reduced material use and generation are the following: (1) Reduction (II) Reuse (III) Recycling (IV). Restore

I, II, III
I, II, III, IV
II, III, IV
III, IV

Correct Answer

A. I, II, III

Explanation

The correct answer is I, II, III. The options given are Reduction, Reuse, Recycling, and Restore. Reduction refers to minimizing the amount of material used or generated. Reuse involves using a material or product multiple times before discarding it. Recycling is the process of converting waste materials into new products. Restore, although not explicitly defined, can be interpreted as a form of recycling or reusing to bring something back to its original condition. Therefore, options I, II, and III all contribute to reducing material use and generation.

Wastes made of Polyvinyl chloride (PVC) needs recycling due to its typical uses such as the following: (I) Gas container (II) Food packaging (III) Wire insulatio (IV) Pipe

I, II, III
I and IV
I, II, III, IV
II, III, IV

Correct Answer

A. II, III, IV

Explanation

Polyvinyl chloride (PVC) is a type of plastic that is commonly used in various applications such as gas containers, food packaging, wire insulation, and pipes. These uses make PVC waste materials potentially harmful to the environment if not properly recycled. Therefore, recycling is necessary for PVC wastes that are generated from gas containers, food packaging, wire insulation, and pipes.

Code number for PETE-, PVC-, PP-type of plastic, respectively:(I) No. 1 (II) No. 3 (III) No. 4 IV. No. 5

III, IV, II
II, III, IV
I, II, III
I, II, IV

Correct Answer

A. I, II, IV

Explanation

The correct answer is I, II, IV. This is because the code number for PETE-type plastic is No. 1, the code number for PVC-type plastic is No. 3, and the code number for PP-type plastic is No. 5. Therefore, the correct order of the code numbers for PETE-, PVC-, and PP-type plastic is I, II, IV.

The strategic collection of wastes of the community should be through the following:(I) House-to-house (III) Self-delivered(II) Community bins ( IV) Contracted service

I, II, III, IV
I, II, III
I, III, IV
I, II, IV

Correct Answer

A. I, II, III, IV

Explanation

The correct answer is I, II, III, IV. This means that the strategic collection of wastes should include house-to-house collection, community bins, self-delivered waste disposal, and contracted services. This comprehensive approach ensures that waste is collected efficiently and effectively from all sources within the community, whether it is delivered directly by households or through designated community bins. The inclusion of contracted services further enhances the waste management system by outsourcing collection to specialized companies or organizations.

None of the above

Correct Answer

A. None of the above

Explanation

The correct answer is "None of the above" because the Environmental Education and Awareness Act of the Philippines is not represented by any of the given options (RA 9521, PD 984, PD 1096). Therefore, none of the options provided is the correct answer for this question.

The Hazardous Waste number for Busted Fluorescent Lamp?

J201
B206
D407
I101

Correct Answer

A. D407

Explanation

The correct answer is D407 because D codes in the hazardous waste classification system are used for specific types of wastes, including mercury-containing lamps. D407 specifically refers to fluorescent lamps that are intact or broken. This waste must be properly managed and disposed of due to the potential release of mercury, a toxic substance, if mishandled.

The typical concentration (% by volume) of Methane Gas in Sanitary Landfill

30-50
50-70
20-25
10-25

Correct Answer

A. 50-70

Explanation

The typical concentration of methane gas in a sanitary landfill is 50-70% by volume. This is because methane is a byproduct of the decomposition of organic waste in landfills. As the waste breaks down, it produces methane gas, which is highly flammable and contributes to climate change. Landfills are designed to capture and control this methane gas through systems such as gas collection wells and covers. The concentration of methane in a landfill can vary depending on factors such as the age and composition of the waste, as well as the efficiency of the gas collection system.

Within 5 years upon the effectivity of the ESWMA (by year 2006), the LGU should divert at least _________ of the waste from disposal facilities through re-use, recycling, composting and other resource recovery activities.

10
15
25
30

Correct Answer

A. 25

Explanation

The correct answer is 25. Within 5 years of the ESWMA taking effect in 2006, the local government unit (LGU) should divert at least 25% of waste from disposal facilities through re-use, recycling, composting, and other resource recovery activities. This means that the LGU should actively promote and implement waste management practices that reduce the amount of waste sent to disposal facilities, and instead focus on methods that can recover resources from the waste, such as recycling and composting.

True (Both statements are correct)
False (one or both statements are incorrect)

Correct Answer

A. True (Both statements are correct)

Explanation

The explanation for the given correct answer is that the statement correctly identifies the three major categories of technologies for solid waste management, which are bio-processing, thermal processing, and sanitary landfill. Additionally, the statement accurately defines source separation as the sorting of solid waste into its component parts at the point of generation. Therefore, both statements are correct.

A soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. This refers to:

GC-ICP
AAS
Jar Test
TCLP

Correct Answer

A. TCLP

Explanation

The correct answer is TCLP, which stands for Toxicity Characteristic Leaching Procedure. This method is used to simulate leaching of chemicals from a soil sample through a landfill. It is an analytical method that helps determine the potential for hazardous waste to leach into the environment. The TCLP test involves subjecting the soil sample to specific conditions, such as acidic pH and agitation, to assess the release of toxic substances.
