“…Last accessed: April 10 th , 2023). A special type of glossy and durable paper, reusable and photodegradable, has been obtained using small amounts of plastics, even recycled waste, and powdered minerals (up to 80%), by a process having a very low level (if not at all) of water and air pollution (Indriati et al 2020). Recycling and up-cycling in the papermaking are well illustrated by the new 100% recyclable and biodegradable paper made of 10% paper waste, and residues from leather manufacturing that can replace up to 25% wood tree pulp (https://www.favini.com/gs/en/fine-papers/remake/features-applications, accessed: April 10 th , 2023).…”

Paper, which is in fact a very complex cellulose-based product derived from different lignocellulosic resources, is usually regarded as a simple omnipresent commodity in our lives. Wood fibers derived from trees are the most employed sources for papermaking purposes. From an environmental protection perspective, and for their essential role in our life (they give us the life itself through their foliar system supporting the photosynthesis process), trees should not be extensively cut down and they should be used less and less for papermaking. Thus, employment of non-woody alternative sources for papermaking could be exploited more as an attractive and feasible option.

“…The paper being printable, recyclable and water proof is a plastic alternative with good credentials. Stone papers can be used to make certified food-grade packaging, greaseproof paper wraps, ziplock bags etc (Ezcurra et al, 2012;Chu et al, 2019;Indriati et al, 2020).…”

Overuse of plastic that live on in nature has created a global crisis on our ecosystem and environment. Small particles of plastic of diameter upto 5mm called microplastics are found everywhere clogging the arteries of our mother nature. Microplastics absorb organic contaminants and act as vectors of potentially hazardous chemicals in living system. To save the flora and fauna of the earth from hazards of microplastics, the potential sources of microplastics should be identified and use of plastics be controlled and if possible terminated, Plastic litters should be recycled and reprocessed. To decrease our dependency on plastics, alternatives should be found. Research on plastic recycling and finding plastic alternatives should be scaled up. Most importantly common people should be made aware of the hazards of use of plastic. Public opinion in favour of termination of plastic use would be the most powerful weapon in saving the earth from this crisis

Biomedical waste (BMW) incineration is the most used alternative disposal method in developing countries, such as Ghana. The improper disposal of incinerator-generated bottom ash (BA) is a significant concern due to the hazardous nature of waste. A study was conducted at Tema Hospital (TGH) and Asuogyaman Hospital (VRAH) incinerator sites. The BA samples were sent to the Council for Scientific and Industrial Research, Institute of Industrial Research, Ghana. The BA samples were weighed with fisher analytical balance, ground, and sieved with standard grade meshes of 120, 100, and 80 to determine the BA particle size distribution. The chemical composition and heavy metals were analysed using X-ray fluorescence spectrometry (XRF) and atomic absorption spectroscopy (AAS) techniques. The results indicated the chemical composition of the analysed BA samples was CaCO 3 (49.90%), CaO (27.96%) and MgCO 3 (6.02%) for TGH and CaCO 3 (48.30%), CaO (27.07%), and SiO 2 (6.10%) for VRAH, respectively. The mean concentration ( M ) (kg m −3 ) and standard deviation ( SD ) for TGH in the BA were 7.082 ± 0.478 (Ti), 4.657 ± 0.127 (Zn) and 4.271 ± 1.263 (Fe), while that of VRAH consisted of 10.469 ± 1.588 (Ti), 7.896 ± 2.154 (Fe) and 4.389 ± 0.371 (Zn). Therefore, the heavy metals’ mean concentration at the BA is above the WHO permissible limits of soil, i.e., 0.056 kg m −3 (Ti), 0.085 kg m −3 (Pb), 0.100 kg m −3 (Cr) and 0.036 kg m −3 (Cu). Furthermore, the heavy metal mean concentrations of TGH and VRAH present in the BA analysed samples were ranked in descending order: Ti > Zn > Fe and Ti > Fe > Zn, respectively. It is therefore recommended that BA must be properly disposed of because of the hazardous nature of heavy metals present in the analysed samples, which are able to cause environmental and public health issues.
