Know Your Enemy—
SARS-CoV-2 Risk Of Exposure Via Organics Recycling Pathways, Part II

The virus that causes COVID-19 is SARS-CoV-2. In Part I, I discussed that much of what we know about COVID-19 centers around the behavior of viruses from the same family as SARS-CoV-2, and increasingly some of it from the virus itself. The last section of Part I explained how this virus is wrapped up in an envelope and that outside of your body, enveloped viruses, almost certainly including SARS-CoV-2, are frail and delicate things.

That knowledge informs the focus of Part II — putting SARS-CoV-2 in the context of municipal wastewater treatment and composting. The first thing to consider is whether there is a real possibility that any of the virus, let alone a gang of these hijackers, could make it into the wastewater plant or the compost feedstocks. We know that there is some fecal shedding of SARS-CoV-2, so the answer there is within the realm of possibility on the wastewater.

Disintegration Rate Of Compostable Products At Industrial Facility, Part II

By Maarten van der Zee and Karin Molenveld
Part I of this article summarized the scope and research methods for a recent study at Wageningen University & Research in the Netherlands that analyzed the fate of compostable packaging in an industrial composting plant. The central aim of the study, “The fate of (compostable) plastic products in a full scale industrial organic waste treatment facility,” was to gather more empirical data on whether the disintegration rate of compostable products is sufficient to be compatible with current organic waste treatment practices in the Netherlands. 

2,900 Commercial Organics Customers
In Massachusetts

RecyclingWorks Massachusetts, managed by the Center for EcoTechnology (CET) for the Massachusetts Department of Environmental Protection (MassDEP), collects annual data from organics haulers on the number of commercial entities in the state contracting for organics hauling services. In 2019, the number of reported commercial customers increased by 26% to 2,900 from the previous year, representing an additional 600 businesses and institutions source separating and diverting organics. At least 40 companies are offering organics hauling services for commercial entities. Massachusetts’ commercial organics disposal ban went into effect in October 2014; businesses and institutions generating >1 ton/week of food waste are required to divert it from disposal.

Financing AD Biogas Development In Quebec

A $20 million fund for anaerobic digestion (AD) projects that produce renewable natural gas (RNG) was launched in Quebec, Canada on June 1. The GNR Québec Capital L.P. investment fund was created by Xebec Adsorption, Inc., a global provider of clean energy solutions that include biogas conditioning, and Fonds de solidarité (the Fonds), a capital development fund that channels the pension savings of Quebecers into investments. Xebec and the Fonds each invested $10 million initially into the partnership. Financing will be directed to the agricultural and municipal sectors, providing access to the capital and expertise needed to develop and operate efficient AD facilities to treat organic waste. Creation of a fund of this type for RNG projects is a first in Québec.

Wastewater Based Epidemiology

An article by Dr. Ian Pepper, University of Arizona, in the May 29 edition of the Northwest Biosolids newsletter, discusses Wastewater Based Epidemiology (WBE), a rapidly expanding new discipline formerly known as Sewage Surveillance. “The concept behind WBE is that the concentration of specific microorganisms and/or chemicals in sewage is a reflection of the total inputs of these constituents from a given community,” writes Pepper. “For SARS-CoV-2 and wastewater treatment plants, the concentration of coronavirus in the sewage is a reflection of the total virus load resulting from members of the community served by the plant. Critically important is the fact that the total virus load reflects viruses shed by infected individuals with symptoms, as well as infected individuals who are asymptomatic.
