The world generates 2.01 billion tonnes of municipal solid waste annually, with at least 33 percent of that—extremely conservatively—not managed in an environmentally safe manner. Worldwide, waste generated per person per day averages 0.74 kilogram but ranges widely, from 0.11 to 4.54 kilograms. Though they only account for 16 percent of the world’s population, high-income countries generate about 34 percent, or 683 million tonnes, of the world’s waste.
When looking forward, global waste is expected to grow to 3.40 billion tonnes by 2050, more than double population growth over the same period. Overall, there is a positive correlation between waste generation and income level. Daily per capita waste generation in high-income countries is projected to increase by 19 percent by 2050, compared to low- and middle-income countries where it is expected to increase by approximately 40% or more. Waste generation initially decreases at the lowest income levels and then increases at a faster rate for incremental income changes at low income levels than at high income levels. The total quantity of waste generated in low-income countries is expected to increase by more than three times by 2050. The East Asia and Pacific region is generating most of the world’s waste, at 23 percent, and the Middle East and North Africa region is producing the least in absolute terms, at 6 percent. However, the fastest growing regions are Sub-Saharan Africa, South Asia, and the Middle East and North Africa, where, by 2050, total waste generation is expected to more than triple, double, and double respectively. In these regions, more than half of waste is currently openly dumped, and the trajectories of waste growth will have vast implications for the environment, health, and prosperity, thus requiring urgent action.
Yard debris and food waste combined account for nearly 30% of the materials disposed in UK landfills. These materials can be easily composted in municipal and backyard composting systems and fortunately, composting collection programs have been increasing with increasing waste generation. However, backyard composting may not be an option for many individuals that wish to divert their materials from the landfill because they lack yard space, time or energy or else live in a rental unit; therefore, vermicomposting becomes an attractive alternative.
Vermicompost is the product of earthworm digestion and aerobic decomposition using the activities of micro- and macroorganisms at room temperature. Vermicomposting, or worm composting, produces a rich organic soil amendment containing a diversity of plant nutrients and beneficial microorganisms.
There are several benefits for vermicomposting but the two most popular are
(1) diverting organic residuals from the landfill and reducing trash collection fees and
(2) creating resources from waste materials.
Vermicomposting can be a fun activity for school children, and vermicompost can be utilized in gardens to promote plant growth. Vermicompost can be mixed with potting media at a rate of 10% by volume or else added directly into your soil; both options will provide plants with valuable organic matter, nutrients, and a diversity of beneficial microbes.
