Trinidad and Tobago generates the most trash per capita in the world

Trinidad and Tobago is said to produce 14.4 kilograms per capita per day of municipal solid waste (MSW). The amount of MSW produced by Trinidad and Tobago is 150 per cent more than second place Kuwait.

Repeating Islands


Joel Julien (Trinidad Express) writes that, according to a report by Worldatlas—“Countries Generating The Most Trash Per Capita”—Trinidad and Tobago generates the most trash per capita in the world. Besides Trinidad and Tobago, the Bahamas, St. Lucia, Barbados, Guyana, St. Kitts and Nevis, and Antigua were among the top ten. Here are excerpts:

[. . .] Sadly, Trinidad and Tobago came out in first place. According to Worldatlas “a lack of recycling facilities” contributed to Trinidad and Topbago’s “dire waste management issues”. We were also slammed for our “pervasiveness of littering”.

Trinidad and Tobago is said to produce 14.4 kilograms per capita per day of municipal solid waste (MSW). The amount of MSW produced by Trinidad and Tobago is 150 per cent more than second place Kuwait. Kuwait is said to produce 5.72 kilograms per capita per day of MSW. The worldwide average for MSW production is 1.2kg.

The Impact of Lead

The greatest environmental downside towards utilizing lead for lead acid batteries is the waste produced in processing lead and the damage created in the mismanagement of lead that is being recycled (as lead still is a toxic material to deal with). Our greatest priority moving forward with lead should be to utilize research efforts into producing cleaner processes for handling lead, and researching stricter procedures for the recycling of lead.


It’s no stretch to say that electricity powers our world. A wide variety of appliances serve critical purposes in ensuring the health, efficiency, and security of the human race. From automobiles to medical appliances, it is no stretch to claim that batteries serve a critical role in society to power crucial portable appliances.

As discussed in my previous blog post, Lead Acid batteries firmly stand as the industry standard to power our heaviest appliances, mainly due in part to it’s economic advantage over alternatives on the market. However, there do exist alternatives. From older batteries, such as Nickel Cadmium, to more modern batteries, such as Lithium-ion, Lead Acid batteries fall short in smaller devices due to the energy and weight efficiency exhibited by  the newer Lithium Ion battery.

Generating Energy from Aquarium Guck

Algae are capable of producing biodiesel, a type of biofuel that is produced by chemically reacting fats (called lipids) with an alcohol (a compound that contains –OH—known as hydroxyl—in their chemical structure). Biodiesel production through algae initially requires the organisms to produce lipids, molecules that are essential for maintaining their cellular activities. Many (but not all) lipids cannot dissolve in water, and typically contain hydrogen and carbon in their structure.

It turns out that all that green guck that built up in your aquarium was capable of doing more than you ever thought: Generating fuels that can potentially replace fossil fuels in the distant future.

Human factors (anthropogenic activities) such as burning fossil fuels are increasing the concentrations of CO2 into the atmosphere, causing a climate warming (global warming).

In an attempt to decrease the amount of atmospheric CO2, algae are considered an alternative solution. Algae are microorganisms that are capable of harnessing solar energy, nutrients, and CO2 to produce compounds for their own survival (i.e. carbohydrates, fats, proteins, pigments). Some species of microalgae may also grow in the absence of light, while different species require either inorganic (CO2) or organic carbon…

Codigestion: A Developing Trend and Market

One reason for the increased interest in codigestion is the creation of opportunities for the use of biodegradable wastes due to the tremendous number of AD plants online and currently being constructed

Applied Technologies, Inc.

by Dennis Totzke

Codigestion is a term heard often these days, and a concept that will likely increase in popularity as we move through the current tense times towards a friendlier, more renewable economy.

In general, codigestion refers to the anaerobic digestion (AD) of multiple biodegradable substrates (feedstocks) in an AD system. The more contemporary definition refers to the digestion of a combination of select biodegradable feedstocks with a base substrate that an AD system was designed to handle. The general idea is to maximize the production of biogas in an AD plant by adding substrates that produce much more biogas per unit mass than the base substrate. Two readily available substrates – municipal biosolids and agricultural manure – are the base substrates most often utilized and are located near the bottom of the “biogas per unit mass” scale. However, the benefits that can be realized from codigestion, as well…
